Habitat and Cultural Demands It needs very sunny exhibitions all year round. Irrigations should be measured, waiting for the substrate to dry before watering again. In winter you don't have to water it. It should be borne in mind that in its natural occur sparsely and rarely. Uses It is grown in gardens in isolation. Its striking staff and the thorns that are arranged along its stem attract the attention of visitors to these gardens. Observations You have to be very careful in your handling for its impressive spikes, which can really do a lot of damage.

Synonyms: procera Drake. descoingsii is a of aloe native to Madagascar. It is the smallest aloe plant in the world and is a set of rosette-shaped succulent leaves with a long stem. It is 4-6 cm in diameter. Its state of conservation is disputed, although it appears to be in danger.2 [edit] Aloe descoingsii was described by Gilbert Westacott Reynolds and published in the Journal of South African 24:103, in 1958.3 Etymologaloe: generic name of very uncertain origin: it could be derived from the Greek "als, alós", "salt" - giving ,aloé, oés that designated both the plant and its juice - due to its flavor, reminiscent of the water of the sea.4 From there it went to Latin . , s with the same acceptance, and which, figuratively speaking, also meant "bitter". An Arabic origin, alloeh, has also been proposed, meaning "the bright bitter substance"; but it is most likely of complex origin through the hebreo: ahal, often cited in biblical texts.5 6 ALOE DESCOINGSII descoingsii: epithet awarded in honor of the French botanist specializing in Madagascar; Bernard Descoings (* 1931).7 Aloe rauhii, is a species of in the family . It is native to Madagascar. Aloe rauhii grows without a very short stem or trunk and then forms dense clugs. The up to 20 lanceolate and deltoid leaves form dense rosettes. They are grey-green, sometimes dyed brown 7 to 10 cm long and 1.5 to 2 cm wide. In it are numerous and scattered H-shaped spots. It has white teeth in the cartilaginous margin, approximately 0.5 millimeters in length and is 1 to 2 millimeters away. The are simple or rarely branched and reach a length of 30 centimeters. They are composed of twelve to 18 scarlet pink flowers and brighter at the mouth and 25 millimeters long and at the base narrow. It is a plant with succulent leaves forming a rosette found in Madagascar in the Province of Toliara. Aloe rauhii was described by Gilbert Westacott Reynolds and published in the Journal of South African Botany 29:151, in 1963.3 Etymologaloe: generic name of very uncertain origin: it could be derived from the Greek "als, alós", "salt" - giving ,aloé, oés that designated both the plant and its juice - due to its flavor, reminiscent of the water of the sea.4 From there it went to Latin . , s with the same acceptance, and which, ALOE RAUHII figuratively speaking, also meant "bitter".

It is native to Madagascar. It is a plant with succulent leaves; which is located in sub-humid, sub-arid in the scrub, in on the face with rocks, at an altitude of 0-499 meters, in Madagascar in the provinces of Fianarantsoa provinces and Toliara. Aloe vaombe was described by Decorse & Poiss. and published in Recherches sur la Flore Méridionale de Madagascar 96, in 1912.3 Etymologaloe: generic name of very uncertain origin: it could be derived from the Greek "als, alós", "salt" - giving ,aloé, oés that designated both the plant and its juice - due to its flavor, reminiscent of the water of the sea.4 From there it went to Latin . , s with the same acceptance, and which, figuratively speaking, also meant "bitter".

It is a thorny shrub that can reach 150 cm in height. Shrub native to Madagascar, which develops abundantly in ravines, slopes and terraces in half shade and in full sun mainly. For ornamental use, its name refers to the crown of thorns that was imposed on Jesus Christ before his execution. Shrub that can exceed 150 cm in height whose stems end in a terminal rosette of leaves. Its inflorescences are pedunculated that have several blood-red flowers. It differs from similar species because large bracts, 1 to 2 cm long, are fused two-thirds of their length. The flower glands are toothed. Like other euphophobias, Euphorbia milii has a very irritating and caustic latex (milky juice). Avoid contact with skin and eyes. Symptoms of ingestion with scorching abdominal pain, mouth and throat irritation, vomiting. Poisonous, contains 5-deoxyingenol. Its flowering period covers all year round. It is used as an ornamental garden plant for its colorful porte and flowering. This plant requires little care, but needs heat and good drainage. Euphorbia milii was described by Charles des Moulins and published in Bulletin d'Histoire Naturelle de la Societe Linneenne de Bordeaux 1(1): 27–30, pl. 1. 1826.1 EtymologyEuphorbia: generic name derived from the Greek doctor king Juba II of Mauritania (52 to 50 BC - 23), Euphorbus, in his honor – or alluding to his large belly – since he medically used Euphorbia resinifera. In 1753 Charles Linnaeus named the whole gender.2 milii: epithet given in honor of Commander Pierre Bernard Baron Millius (1773 - 1829), governor of Reunion Island.3 EUPHORBIA MILII RED Varieties It is a very variable species, and various varieties have been described; some of these are considered by some authors to be distinct species. Euphorbia milii var. bevilaniensis (Croizat) Ursch - Leandri Euphorbia milii var. hislopii (N.E.Br.) Ursch - Leandri Euphorbia milii var. milii Euphorbia milii var. splendens (Bojer ex Hook.)

Ursch - Leandri (1954 publ. 1955).4 5 Euphorbia milii var. volcanoes Vernacular name[edit] Spanish: crown of thorns, thorns of Christ, crown of Christ, thorn of the lord (Canary Islands). Euphorbia milii , the crown of thorns, plant of Christ or thorn of Christ, called Crown of Christ in Latin America (coroa-de-cristo in Brazil), is a species of in the family Euphorbiaciae, native to Madagascar. The species name commemorates Baron Milius, once governor of Reunion, who introduced the species to France in 1821. [2] It is imagined that the species was introduced to the Middle East in ancient times, and legend associates it with the crown of thorns, used by Christ. It is a succulent shrub or shrub growing to 1.8 m (5 feet 11 inches) tall, with densely thorny stems. Straight, thin spines, up to 3 cm (1.2 inches) long, help you stir over other plants. The leaves are mainly found in the new growth, [2] and are up to 3.5 cm (1.4 inches) long and 1.5 cm (0.59 inches) wide. The flowers are small, supported by a pair of petal-like conspicuous bractes, red, pink or white, up to 12 mm (0.47 inches) wide. [3] The sap is moderately poisonous and causes irritation in contact with the skin or eyes. If swallowed, it causes severe stomach pain, throat and mouth irritation, and vomiting. Poisonous ingredients have been identified as forbol esters. [4] Wat Phrik in Thailand claims to be home to the world's tallest Thorns of Christ plant. [5] Euphorbia milii can spread from cuttings. E. milii is a variable species, and several varieties have been described; Some of these are treated as distinct species by some authors. [3] E. milii var. splendens (syn. E. splendens ) is considered the living incarnation of the supreme deity in Bathouism, a minority religion practiced by the Bodo people of EUPHORBIA MILII WHITE eastern India and Nepal E. milii is non-resistant and does not tolerate temperatures below 10oC (50oF). In temperate areas, it should be grown under glass in full sun. During the summer, it can be placed outside in a protected place, when all the risk of frost is absent. The species [7] and the variety E. milii var. splendens [8] have won both the Royal Horticultural Society's Garden Merit Award. Euphorbia stenoclada is a species of plant in the family . It is endemic to Madagascar. Its natural are subtropical or tropical dry forests and rocky areas, and are threatened by habitat. It is also appreciated as an ornamental plant. Euphorbia stenoclada fue descrita por Henri Ernest Baillon y publicado en Bulletin Mensuel de la Société Linnéenne de Paris 1: 672. 1887.2 Etymology Euphorbia: generic name derived from the Greek doctor king Juba II of Mauritania (52 to 50 BC - 23), Euphorbus, in his honor – or in reference to his large belly – since he medically used Euphorbia resinifera. In 1753 Charles Linnaeus named the whole gender.3 stenoclada: Latin epithet Varieties Euphorbia stenoclada subsp. ambatofinandranae (Leandri) Cremers Euphorbia stenoclada subsp. stenoclada SinonimiaTirucalia stenoclada (Baill.) P.V.Heath The genus Euphorbia (from the family Euphorbiaceae) consists of some 2,000 species of succulent plants, and herbaceous plants from , America and Madagascar. Some species of this genus are: Euphorbia stenoclada, Euphorbia cap-saintemariensis, Euphorbia suzannae, Euphorbia horrida, Euphorbia enopla, Euphorbia resinifera, Euphorbia canariensis, Euphorbia candelabrum, Euphorbia royleana, Euphorbia trigona, Euphorbia bivonae, Euphorbia anachoreta, Euphorbia aphylla, Euphorbia echinus, Euphorbia lambii, Euphorbia rigida, Euphorbia coerulescens, Euphorbia dendroides, Euphorbia balsamifera. It receives the scientific synonym of Tirucalia stenoclada and is native to Madagascar. In English it is known by the vulgar name "Stiver Thicket". They are succulent, bushy (sometimes arboreal), slow-growing plants that reach several meters in height. The stems branch profusely, have tubers and spines and are green and light grey. They do not have leaves but they do have small flowers that EUPHORBIA STENOCLADA are not very decorative although it is not usual for them to flower in pots. They are usually used for cultivation in pots for patios and interiors but are also interesting to form impenetrable barriers. The Stenoclada Euphorbia needs full sun exposure or at least very bright (indoors) and high temperatures. In winter it is better not to suffer temperatures below 6 oC. It can't resist frost. A good for these plants can be a commercial substrate for cacti or a mixture of garden soil and thick sand silica in equal parts. Water moderately in spring and summer waiting for the substrate to dry well; resist the prolonged very well. In winter it is better not to water them. They don't need special subscribers or pruning. They do not usually present serious pest and disease problems, although it is advisable to monitor piglet attacks. The best form of multiplication is from cuttings about 15 cm long taking great care with the irritating latex that these plants give off. The Cuba2 disciple (Euphorbia tirucalli) is a species in the euphorbiaceae family. It is endemic to the dry tropical regions of Africa to India.3 The species is present in all tropical regions of the world and is common throughout its range. The modern distribution of this species seems to be confused by the introduction and subsequent naturalization, so it is difficult to know which countries are part of the range. It is a perennial shrub species with a cylindrical and fleshy stem. Densely branched shrub, often dioeic, reaches a size of 4 meters or a 12 to 15 m tall, with fragile succulent twigs of 7 mm thick, often produced in whorls, longitudinally, finely striated. It is a very hiveping plant, since when coming into contact with the skin, eyes or if it is ingested it can cause a scorching sensation, so it is recommended not to approach this plant. It is toxic, sap can cause sores on the skin, and in the eyes can cause irreversible visual damage. It is suggested to wear glasses and gloves for handling, and keep it away from the usual places where children play. It is found in grasslands and forests forming scrub in the ravines, forests on black clay , at an altitude of 0-2000 meters. E. tirucalli also has uses in traditional medicine in many cultures. It has been used to treat cancer, excretion, tumors and warts in places as diverse as Brazil, India, Indonesia and Malaysia.7 It has also been used as for asthma, cough, ear pain, neuralgia, rheumatism, toothache, and warts in India and Malaysia.8 E. tirucalli has been promoted as an anti-cancer agent, but research shows that it suppresses the immune system, promotes tumor growth, and leads to the development of certain cancers.9 Euphorbia tirucalli has also been associated with tumor lymphoma Burkitt and is thought to be a cofactor of the disease rather than a treatment.10 Milky latex of E. tirucalli is extremely irritating to the skin and mucosa and is toxic.9 Contact with the skin causes severe irritation, redness and a burning sensation; contact with the eyes can cause severe pain, and in some cases temporary blindness for several days. Symptoms may get worse for more than 12 hours. For eye exposures, wash your eyes with fresh, cold water for at least 15 minutes and repeat after a few minutes. Seek medical attention if there is no relief. Antihistamines may provide relief for some people. If swallowed, it can cause burns EUPHORBIA TIRUCALLI to the mouth, lips and tongue. Some deaths have been recorded from ingestion of latex, and anyone after swallowing it should seek medical attention. Euphorbia tirucalli was described by Carlos Linnaeus and published in Species Plantarum 1: 452. 1753.11 EtymologyEuphorbia: a generic name derived from the Greek doctor king Juba II of Mauritania (52 to 50 BC - 23), Euphorbus, in his honor – or alluding to his large belly – as he medically used Euphorbia resinifera. In 1753 Charles Linnaeus named the whole genre. tirucalli: epithet More than 100 species of succulent plants from Asia, Africa and Europe form the genus of the family. Some species of the genus are: Kalanchoe longiflora, Kalanchoe thyrsiflora, Kalanchoe tomentosa, Kalanchoe beharensis, Kalanchoe daigremontiana, Kalanchoe gastonis-bonnieri, Kalanchoe blossfeldiana, Kalanchoe uniflora, Kalanchoe manginii, Kalanchoe Pinnata, Kalanchoe fedtschenkoi, Kalanchoe pumila, Kalanchoe marmorata. It is known by the vulgar name of Long Flower Calanchoe. This species is native to . They are succulent plants of relatively fast growth that reach 60 cm in height and width. Its fleshy toothed leaves are bright green with reddish tones if they receive enough light. They produce floral stems above leaves filled with yellow flowers. They bloom during the summer. They are ideal for use in rock rocks, dry slopes, tassels or pots and planters. The long flower Calanchoe prefers a full sun exposure but can also live in semi-state. It tolerates the heat of the Mediterranean summer but not the cold so the winter safety temperature is at 5 oC. The best soil for these coves would be a garden land with plenty of thick silica sand or a commercial substrate for cacti and succulents. Although they resist drought they will grow better with regular irrigations waiting for the soil to dry between water intakes. In winter reduce the irrigation up to once a month at most. One subscriber will suffice at the start of spring with a little compost. KALANCHOE LONGIFLORA Pruning is only necessary to remove flowers and leaves that have withered. The greatest enemy of these plants is the over-watering that causes fungal diseases (fungus). The best form of multiplication is from cuttings planted in their final place because they with great ease. Kalanchoe orgyalis is a small shrub of the family Crassulaceae very popular for the typical coloration of its leaves. This plant fails to exceed 120 cm in height and develops woody stems (over time) with abundant branches. Unlike other species in the genus, it has a fairly slow growth reaching its maximum proportions in some years. In this species a central stem is always observed much thicker than the branches, managing to maintain the erect porte of the plant throughout its life. It is very common that during the growth of the species only leaves are observed in the apical areas of the stems leaving the rest bare with scars of the ancient leaves. The fleshy leaves are the main attraction of the species for its large size and coloration. Opposite the stem is arranged as are most species in the genus, each pair of leaves forms a 90-degree angle to the previous pair. In this species there is a very conspicuous coloration change during the development of the leaves; in the early stages of development they have a reddish coloration (very similar to the color of the copper metal) on the beam and green-grey on the underside. After developing the leaves, the beam takes on a very striking grey color that contrasts with the copper color of the younger leaves. In all the leaves a groove is formed that folds the through its central region; sometimes this folding is similar to the shape of a spoon calling the copper spoon plant. The flowers are very striking too and appear mainly in large plants. These appear at the apex of the stems in clustered inflorescences. The flowers are small, cylindrical and very striking yellow. This color causes a very attractive contrast with the grayish and copper coloration of the leaves. It usually blooms in spring seasons. KALANCHOE ORGYALIS Within the genus Kalanchoe is one of the species most resistant to drought and extreme heat. It tolerates direct sun exposure without problems if the plant is of considerable size. It is advisable to expose plants of smaller sizes to semi-shade to avoid accelerated dehydration problems. This species also accepts cultivation in illuminated indoors although it is rare to flower. Be very careful in winter with temperatures below 5oC because they cause the root to rot and the fall of the foliage. It is a plant capable of tolerating temperatures above 35oC without problems. The panda plant belongs to the Crasulaceae family and does not usually exceed 50 cm tall. The stems branch from the base and have oval-shaped sessile leaves (no peduncles), covered with fine hairs that give it a velvety feel. These leaves also have a strong, dark- colored border, which has given it the name Panda Plant. It does not flower, although its flowers are very small and sparsely decorative. This Kalanchoe is commonly known as Panda Plant, Velvety Calanchoe or Cat Ears and is native to Madagascar. They are used in pots for terraces and balconies. It's a good place to change the land every 2 years. They need exposure to full sun and, thanks to their hairs, resist heatstroke well. It does not suit temperatures below 8 oC, being its ideal temperature in winter of about 10 oC. The velvety calanchoe will be grown in a soil formed, in equal parts, of peat, sand and mulch. KALANCHOE TOMENTOSA They are drought-resistant plants that only need a moderate weekly irrigation throughout the year, less in winter than it will be every 2 weeks. They do not need a subscriber, it is enough with the mulch that we will include in the renewed substrate every 2 years. Panda plants are not usually attacked by pests and diseases, they only fear over-watering. The best way to multiply them is by cutting stem or leaf, as the are very small and difficult to handle. DECARYI Other names: fake Japanese pepper, Japanese pepper. The genus Operculicarya belongs to the family Rutaceae (rutáceas) and is represented by a few species, currently only 5 have been described, all of which originated in Madagascar. is sometimes confused with the Zanthoxylum piperitum, also from the rubaceous family, because in shops and nurseries both are referred to as a Japanese pepper, so you have to look closely at the characteristics of the rutáceas, Operculicarya decaryi, and they are: Tree native to Madagascar, small to medium sized, which behaves like deciduous during the cold season when grown outdoors or perennials if the winter is mild or grown in a greenhouse. Trunk with rough, light-colored bark that has small spines on the branches, usually at the base of the leaf birth. compound leaves (pinnate) with an odd number of small oval and opposite leaflets (7 to 11), alternate, intense dark green, aromatic and turned yellow in autumn. Very small flowers, greenish yellow, very aromatic, fruity, located in the axillary areas of the new branches that appear in spring. There are male , that is, with stamens in the flowers, and female trees, that is, with pistils in the flowers, so if we want it to bear fruit, we must grow trees of different sex or they will not fruit. Its fruits are round and pink or reddish, spicy flavor and also very aromatic. It should also not be confused with the trees of the genus Osteomeles, of the rosacea family, since its leaves and general appearance bear a certain resemblance to the genus Operculicarya, although its flowers are completely different. Although this genus is used as a bonsai very recently, at least in Europe, but it may spread quickly, at least among beginners, due to its resistance, easy and tendency to develop a good trunk and nebari base of a relatively quickly. The small size of its pinnate leaves, the brightness of its leaves and the aroma of its flowers make it a real delight. Although it withstands the cold well, it is advisable to protect you from intense cold, especially you have to watch for strong frosts and cold, dry . A cold greenhouse could be a good solution for the harshest winter areas, trying to put it back outdoors when conditions permit. In this situation it could be preserved all or almost all leaves. Once you have found your most suitable location, you should not move it because you resent the transfers, especially if they are frequent. Irrigations should be every time the surface of the earth is dry, doing so thoroughly, that is, until abundant water comes out through the drainage holes, avoiding permanent watering of the soil to avoid an excess of moisture that rots its . It prefers very well drained soils. However, it does not withstand drought and its roots need regular and permanent moisture so it is necessary to prevent the soil from being completely dry and is very sensitive to excess heat and dry air, which quickly causes the leaves to wither. Frequently pay for a quality organic fertilizer, especially during the time of vigorous growth, i.e. from spring to autumn. During the winter and the hottest time of summer, the amount of fertilizer should be reduced because they are times with little or no growth. We can help reduce the size of the leaves, as well as with good outdoor exposure in full sun with the supply of fertilizers richer in phosphorus (P) and potassium (K) than in nitrogen (N) so as not to encourage the development of its leaves, in addition we encourage fruiting. We must not forget that we cannot: fertilized a transplanted tree, you have to wait for it to sprout. Water a tree grown outdoors after frost or when there is a risk of frost. During the beginning of spring, every 2 or 3 years due to the large number of roots it develops, just a little before the sprouting of the year begins, when the shoots are swollen, although in the old specimens can be transplanted every 3 years and in the young can be annually. Operculicary tolerates any type of soil, although it does not withstand soils that are too alkaline (PH greater than 7.5). A good mixture of substrate for an operculicary could be a mixture of soil with 35% coarse grain sand or equivalent material (volcanic earth, etc.) and 65% mulch, or any of the prepared mixtures that we can find in stores such as the bidama. In any case, it has to be a mixture with excellent drainage. It should not be forgotten that the land used must always be new and clean and never reused from other crops in order to avoid contamination (fungus, diseases, pests, etc.) that could have affected other trees. It is advisable to protect the tree after transplantation for a couple of months, placing it in a very well-lit place but avoiding direct exposure to the sun. Wilted leaves should be removed to prevent the appearance of fungi and unwanted or dry branches can be removed at any time. You should never prune drastically, if the tree is not healthy and vigorous. In addition to pruning for modeling, you have to prune to get a structure that allows the arrival of light to all branches and all sheets can perform photosynthesis. In general, we should remove: all the shoots of the base of the trunk, the branches that cross, the opposite branches, the branches that grow very vertical or that do so into the trunk. Although its branches are relatively flexible, it is advisable to protect the bark of the trunk and branches as it is damaged very easily. You should keep an eye on the wire marks on the bark because of how quickly they fatten and grow, usually the wire should be removed at the time the appearance of marks on the bark will begin. It is advisable not to water the day before wiring. Operculicary is quite resistant and hard to pests and diseases, but in any case, we must remember that if we need to use some phytosanitary treatment, it must be specific against the pest or disease and constant in time until eliminate it completely. geayi is a species of Pachypodium that originated in southwestern Madagascar. It has a pachycaul gris untroncometallic and the leaves are thin and greyish green, with a bright pink rib. The plant has white flowers. is one of the largest species in Madagascar.

PACHYPODIUM GEAYI

FLOR PACHYPODIUM GEAYI The genus Pachypodium, from the family , is composed of about 25 species of succulent trees and shrubs, mostly from Madagascar. Some species are: , Pachypodium ambongense, Pachypodium geayi, Pachypodium baronii, . It is known by vulgar names of Palma or Palm of Madagascar. It is a succulent plant with thick columnar stem covered with spines about 3 cm in length, branched only at the tip and that can measure up to 3 meters in height. It has leaves very similar to those of the Nerium oleander (Adelfa) plant, bright green. The flowers appear at the apex of the plant and are usually white or reddish. They bloom during the summer. They produce curious fruits in the form of small bananas. They are slow-growing plants that are used as isolated specimens in the garden (weather permitting) or to create impenetrable barriers, although it is most common to grow them in pots such as indoor or outdoor plants in patios and terraces. The Madagascar Palm requires a sunny or well-lit exposure (indoors) and high temperatures; you don't want temperatures below 10 oC. It is very important that the soil is well drained as it does not like excessive moisture (neither does high ambient humidity). A good mixture would be 50% leaf mulch and another 50% silica sand. Water moderately, about 2 times a week in summer and never water. In winter it is convenient to stop watering. We can pay monthly with a fertilizer for cactus in spring and summer. PACHYPODIUM LAMEREI These plants are resistant to common pests and diseases and only fear excess water. They can be multiplied from seeds sown in spring that germinate within a few days but that it is important to soak a day before planting.
