Alaribe et al Tropical Journal of Pharmaceutical Research April 2018; 17 (4): 741-749 ISSN: 1596-5996 (print); 1596-9827 (electronic) © Pharmacotherapy Group, Faculty of Pharmacy, University of Benin, Benin City, 300001 Nigeria. Available online at http://www.tjpr.org http://dx.doi.org/10.4314/tjpr.v17i4.25 Review Article Possible roles of Eucomis autumnalis in bone and cartilage regeneration: A review Franca N Alaribe, Makwese J Maepa, Nolutho Mkhumbeni, Shirley CKM Motaung Department of Biomedical Sciences, Tshwane University of Technology, Pretoria 0001, South Africa *For correspondence: Email: [email protected]; Tel: +27-123826265/6333; Fax: +27-123826262 Sent for review: Revised accepted: 23 October 2017 Abstract In response to the recent alarming prevalence of cancer, osteoarthritis and other inflammatory disorders, the study of anti-inflammatory and anticancer crude medicinal plant extracts has gained considerable attention. Eucomis autumnalis is a native flora of South Africa with medicinal value. It has been found to have anti-inflammatory, anti-bacterial, anti-tumor/cancer, anti-oxidative and anti- histaminic characteristics and produces bulb that have therapeutic value in South African traditional medicine. Despite the widely acclaimed therapeutic values of Eucomis autumnalis, its proper identification and proper knowledge, morphogenetic factors are yet to be efficiently evaluated. Similar to other plants with the same characteristics, E. autumnalis extract may stimulate bone formation and cartilage regeneration by virtue of its anti-inflammatory properties. This review provides data presented in the literature and tries to evaluate the three subspecies of E. autumnalis, highlighting their geographical location in South African provinces, their toxicity effects, as well as their phytochemistry and anti-inflammatory properties. -
Hill View Rare Plants, Summer Catalogue 2011, Australia
Summer 2011/12 Hill View Rare Plants Calochortus luteus Calochortus superbus Susan Jarick Calochortus albidus var. rubellus 400 Huon Road South Hobart Tas 7004 Ph 03 6224 0770 Summer 2011/12 400 Huon Road South Hobart Tasmania, 7004 400 Huon Road South Hobart Tasmania, 7004 Summer 2011/12 Hill View Rare Plants Ph 03 6224 0770 Ph 03 6224 0770 Hill View Rare Plants Marcus Harvey’s Hill View Rare Plants 400 Huon Road South Hobart Tasmania, 7004 Welcome to our 2011/2012 summer catalogue. We have never had so many problems in fitting the range of plants we have “on our books” into the available space! We always try and keep our lists “democratic” and balanced although at times our prejudices show and one or two groups rise to the top. This year we are offering an unprecedented range of calochortus in a multiplicity of sizes, colours and flower shapes from the charming fairy lanterns of C. albidus through to the spectacular, later-flowering mariposas with upward-facing bowl-shaped flowers in a rich tapestry of shades from canary-yellow through to lilac, lavender and purple. Counterpoised to these flashy dandies we are offering an assortment of choice muscari whose quiet charm, softer colours and Tulipa vvedenskyi Tecophilaea cyanocrocus Violacea persistent flowering make them no less effective in the winter and spring garden. Standouts among this group are the deliciously scented duo, M. muscarimi and M. macrocarpum and the striking and little known tassel-hyacith, M. weissii. While it has its devotees, many gardeners are unaware of the qualities of the large and diverse tribe of “onions”, known as alliums. -
William Herbert (1778--1847) Scientist and Polymath, and His Contributions to Curtis's Botanical Magazine
WILLIAM HERBERT (1778–1847) SCIENTIST AND POLYMATH, AND HIS CONTRIBUTIONS TO CURTIS’S BOTANICAL MAGAZINE Alison Rix ‘Hon. and Rev. W. Herbert, afterwards Dean of Manchester, in the fourth volume of the ‘Horticultural Transactions’, 1822, and in his work on the ‘Amaryllidaceae’ (1837, pp. 19, 339), declares that ‘horticultural experiments have established, beyond the possibility of refutation, that botanical species are only a higher and more permanent class of varieties’. He extends the same view to animals. The Dean believes that single species of each genus were created in an originally highly plastic condition, and that these have produced, chiefly by intercrossing, but likewise by variation, all our existing species’. [Preface to the third edition (1860) of On the Origin of Species,by Charles Darwin] The Hon. and Rev. William Herbert, often known as Dean Herbert, to whom Vol. 65 (1839) of Curtis’s Botanical Magazine was dedicated, was an exceptional polymath – a poet and classical scholar, linguist, reforming MP, clergyman – as well as amateur botanist and botanical artist. His best-known botanical work, illustrated with 48 of his own paintings, was the two volume work Amaryllidaceae, quoted above by Darwin. Although this extraordinary man counted botany as just one of his many interests, his output was prodigious; in addition to studying and breeding plants, such as Crocus, Gladiolus, Hippeastrum, Narcissus and Rhododendron, he also wrote and drew prolifically for journals such as Curtis’s Botanical Magazine and its rival publication, Edwards’s Botanical Register. In addition to Darwin, he corresponded with many other notable people, including Sir William Hooker and William Fox Talbot, and his letters paint a picture of a rather serious and industrious character. -

ERYTHRONIUMS IN CULTIVATION © Ian Young ERYTHRONIUMS IN CULTIVATION © Ian Young Erythronium californicum ERYTHRONIUMS IN CULTIVATION © Ian Young Erythronium californicum Erythronium californicum filaments are narrow, ribbon-like with milky white pollen , the flowers are also creamy white with a yellow centre; some forms have dark red zig zag patterns around the centre. Erythronium californicum is another excellent garden plant which is most often seen under the cultivar name of Erythronium ‘White Beauty’ this is readily available. I include ‘White Beauty’ here, rather than under hybrids, as there are no morphological indications that any other species is involved. What makes this form such a good garden plant is its ability to tolerate a wide range of garden types and increase well by division: a healthy well- grown bulb can make two new flowering sized bulbs plus have several smaller offsets every year – it also regularly sets seed. Erythronium ‘White Beauty’ ERYTHRONIUMS IN CULTIVATION © Ian Young Erythronium californicum All forms are free flowering, setting seed most years provided the weather conditions at flowering time are not too cold and wet. Erythronium ‘White Beauty’ has fewer seeds in the capsule compared to other forms; about one third of the number. Erythronium californicum seeds ERYTHRONIUMS IN CULTIVATION © Ian Young Bulb On the left is a group of Erythronium californicum bulbs showing the typical shape – the longer thin ones are younger bulbs still taking themselves down into the ground seeking the best conditions. Most forms will increase by offsets, soon forming clumps – forms such as ‘White Beauty’ form clumps quickly, see below, and are best lifted and divided every three to five years to maintain good flowering. -
Moraea Insolens | Plantz Africa About:Reader?Url=
Moraea insolens | Plantz Africa about:reader?url=http://pza.sanbi.org/moraea-insolens pza.sanbi.org Moraea insolens | Plantz Africa Introduction Moraea insolens is a critically endangered, cormous plant, with dazzling orange-red or rarely white- or cream-coloured, salver-shaped blooms, with prominent, deep brown markings to attract its beetle pollinators. It is very rare in cultivation, but can be successfully grown as a container subject. Description Description This deciduous, winter-growing geophyte grows 200–350 mm high and has a small, rounded corm, protected by a covering of hard, light brown outer tunics. The corm produces two, dark brown, basal sheaths and has a solitary, linear, bright green, channelled leaf. The slender flower stem has prominent nodes and is sometimes branched, 1 of 7 2017/02/15 02:42 PM Moraea insolens | Plantz Africa about:reader?url=http://pza.sanbi.org/moraea-insolens producing a succession of salver-shaped flowers, each lasting three days, from between two spathe bracts. The tepals vary in shades of light to bright orange-red and are rarely white or cream-coloured. The three outer tepals are larger than the three inner ones and all are adorned with a deep brown, arrow-shaped marking near the base, sometimes outlined in white. The filaments are united into a central column with three long anthers symmetrically arranged opposite the three outer tepals. The anthers produce sticky, bright orange pollen. The fruit is an elliptic capsule containing many small, light brown, irregularly shaped seeds. The plant flowers from mid- to late spring (mid-September to mid-October) and is completely dormant in summer. -
Eucomis Bicolor Baker) an Ornamental and Medicinal Plant
Available online at www.worldscientificnews.com WSN 110 (2018) 159-171 EISSN 2392-2192 Chitosan improves growth and bulb yield of pineapple lily (Eucomis bicolor Baker) an ornamental and medicinal plant Andżelika Byczyńska Department of Horticulture, Faculty of Environmental Management and Agriculture, West Pomeranian University of Technology, Szczecin, Poland E-mail address: [email protected] ABSTRACT The wide demand for natural biostimulants encourages the search for new, alternative sources of substances with high biological activity. Chitosan can promote plant growth and root system development, enhance photosynthetic activity, increase nutrient and metabolite content. Eucomis bicolor, commonly known as the ‘pineapple lily’, is not widely known in terms of cultivation and biological activity. The aim of the experiment was to determine the effect of chitosan on growth of Eucomis bicolor. To the best of our knowledge, this is the first study to describe the effect of chitosan on morphological features of Eucomis bicolor. The results showed that soaking Eucomis bicolor bulbs in a chitosan solution before planting has stimulated the growth, flowering and yield of bulbs. Treating the plants with chitosan at 50 mg/L had the most beneficial effect on the number of leaves per plant, the relative chlorophyll content in the leaves as well as the number of bulbs per plant. Chitosan has a multi-directional, positive effect on plant growth and can be used as a potential biostimulant.

The New Kirstenbosch Bulb Terrace
- Growing indigenous Working with the seasons The new Kirstenbosch Bulb Terrace by Graham Duncan, Kirstenbosch Heavy winter rains, inadequately drained soils and insufficient winter light lev els experienced in many parts of Kirstenbosch preclude the display of a wide vari ety of our spectacular wealth of winter-growing bulbous plants in the garden itself. In addition, the depredations of molerats, and more importantly, marauding por cupines place further constraints on bulbs that can be displayed to the public. For these reasons the more fastidious species are cultivated under cover in the Kirstenbosch bulb nursery and displayed in containers, in season, inside the Kay Bergh Bulb House of the Botanical Society Conservatory. Although bulbous plants that are able to stand up to the rigours of general gar den cultivation are displayed in many parts of the garden, no section is specifical ly dedicated to bulbs. However, with the recent completion of the Centre for Home Gardening, an area known as the Bulb Terrace has been specifically provided for the display of both winter- and summer-growing bulbs. We hope these displays will draw attention to the many bulbous species suitable for home gardens. Passing through the Centre for Home Gardening towards the garden, the Bulb Terrace comprises eight broadly rectangular beds on either side of the sloping main bricked walkway adjacent to the new Kirstenbosch Tearoom. Four beds on each side of the walkway alternate with wooden benches. Quantities of heavy, poorly ABOVE: The dwarf Watsonia coccinea provides a brilliant splash of reddish-orange in mid-September.
