Enterolobium cyclocarpum Specimen in El Canchol, Jalisco Guanacaste (Costa Rica) Scientific classification Kingdom: Plantae (uninked): Angiosperms (not classification): Eudicots (not classification): Rosids Order: Fabales Family: Fabacea Genus: Enterolobium Species: E. cyclocarpum Binomial name Enterolobium cyclocarpum(Jacq.) Mr Griseb. Different synonyms, see Text Elephant-ear seedpod shape. Enterolobium cyclocarpum, commonly known as guanacaste, dear dear, monkey ear tree or elephant-ear tree, is a species of flowering tree in the pea family, Fabaceae, which is native to the tropical regions of the Americas, from central Mexico in the south to northern Brazil (Roraima) and Venezuela. It is known for its large proportions, its large, often spherical crown, and its curiously shaped semipods. The abundance of this tree, especially in the province of Guanacaste, Costa Rica, where it is appreciated for the shaded relief it provides from the intense sun, coupled with its immensity, have made a widely recognized species. It is the national tree of Costa Rica. North America is often called elephant ear tree, due to the shape of semipods. Other common names include the devil's ear and ear shaft, parota and orrojàn (Spanish) or huanacaxtle (Nahuatl). In El Salvador, he is known as a conacaste. [2] On the Yucatan Peninsula, it is known as the Maya, pich. In Panama he is known as a corot. Description[3] The guanacaste is a medium and large tree, growing up to 25-35 m in height, with a trunk up to 3.5 m in diameter. Unusual in a tree of this proportion, the distressals are completely deficient. The bark is light gray, with prominent vertical cracks in dark red-brown. In young trees these cracks are closer together. and their confluence gives a characteristic reddish hue to the bark of guanacaste saplings. Older specimens often have broken bark, or scarred. The crown is wide and widely spread. The height at which branches first occur along the trunk – as well as the overall shape of the tree – vary greatly between individuals and are habitat- dependent features. Often, guanacaste trees grow as individual specimens in a sunny pasture. Under these conditions, massive, extensive, extensive, the limbs emerge low on the bolines, forming giant, hemispherical, widely diffused crowns. In the forest (where competition for light is intense) trees tend to become taller, and branching occurs at a higher level. The shapes of the trees thus become a little narrower, although the crowns are still rounded, and the hemispherical forms are maintained by those that have reached the canopy. The alternating leaves are composed bipinnate, 15-40 cm long and 17 cm wide with a petiole of 2-6 cm with 4-15 pairs of fins, each fin with leaflets from 40 to 70; the leaflets are thin oblong, 8-15 mm long by 2-4 mm wide. Near its base, the twiggy petiole lays bare a small raised oval gland. The leaves are confined to the outer shell of the crown, but are abundant enough to make them moderately dense and green. Guanacaste is evergreen, or briefly deciduous for 1-2 months during the dry season. Most of the foliage is poured in December, at the beginning of the dry season. At the end of February, a surge in growth is underway that will restore a fresh and thick crown by April. In conjunction with the renewal of the leaves is the appearance of globular inflowers (3 cm) in the axes of the new leaves. Supported by a long pedestal (4 cm), each spherical white head – consisting of about fifty individual flowers – sports thousands of thin and filamentous stamens as its main feature. The flowers themselves each consist of about twenty stamens and a single pistil, tied together with the base by a short, green, tubular corolla and an even shorter calyx, only 5 mm long. Guanacaste flowers are very fragrant, and during periods of intense flowering their smell permeates the air for many meters in all directions. In Manuel Antonio National Park near Quepos, Costa Rica, flowering lasts from late February to early April. Surprisingly, no noticeable fruit activity immediately follows the decline of the flower. Rather, nine or ten months pass before small green pods first appear high in the crown by December. They reach the maximum size by February and finally begin to ripen in March - a whole year after flowering has ceased. Fruit ripening lasts from March to April, while green pods turn brown in the guanacaste crown and are slowly poured. Vigorous trees will produce large crops on an almost annual basis. In June, guanacaste seedlings can already be seen, germinating in the wet soil of the first rainy season. Guanacaste fruits are large (7-12 cm in diameter), shiny and spiral dark brown indehiscent pods, shaped like orbicular discs. Their shape the usual fruit of Mimosoideae – a long, narrow, flattened pod – taken and wrapped around an axis perpendicular to its floor. Made of thick soft tissues with a feeling of leathery, the pods contain 8-20 radially arranged seeds, 14.5–17.5 mm long, 7.8–11.2 mm wide and 6.2–7.2 mm thick and weighing about 1 g. Guanacaste seeds are brown and with a conspicuous light brown or orange ring. They are very hard, similar to small stones rather than tree seeds in their strength and durability. For germination to occur, the coat of hard seeds must be broken to allow water to reach the embryo. Otherwise, the seeds will be dormant indefinitely. Ardillo (Cojoba arborea) and iguano (Dilodendron costaricense) have similar bipinnate leaves with extra-fine leaflets. Although of equally impressive stature, these two trees can be easily distinguished from the guanacaste: the ardillo has brown brown brown, heavily wrinkled and rough - nothing like the unmistakably gray and vertically mottled bark of the guanacaste. The leaflets of the iguano are serrated (an unusual feature in a bipinnate tree), while those of the guanacaste are whole. Ecology Branches and foliage of a young enterolobium cyclecarpum, about 3 years old, in Naiguata, Venezuela, guanacaste trees seem to delay the onset of fruit development - about nine months - so that the ripening of the seeds will coincide with the onset of the rainy season. This adaptive behavior is presumably an adaptation to give germination seedlings as much time as possible to establish root systems before the start of the next dry season.

Apartado postal 70- 233, 04510 México D. F., Mexico. [email protected] Abstract. Trees or tree-like plants are defined here broadly as perennial, self-supporting plants with a total height of at least 5 m (without ascending leaves or inflorescences), and with one or several erect stems with a diameter of at least 10 cm. We continue our compilation of an updated list of all native Mexican tree species with the dicotyledonous families Asteraceae (36 species, 39% endemic), Leguminosae with its 3 subfamilies (449 species, 41% endemic), and Rubiaceae (134 species, 24% endemic). The tallest tree species reach 20 m in the Asteraceae, 70 m in the Leguminosae, and also 70 m in the Rubiaceae. The species-richest genus is Lonchocarpus with 67 tree species in Mexico. Three legume genera are endemic to Mexico (Conzattia, Hesperothamnus, and Heteroflorum). The appendix lists all species, including their original publication, references of taxonomic revisions, existence of subspecies or varieties, maximum height in Mexico, and endemism status. Key words: biodiversity, flora, tree definition. Resumen.

  • The Role of the Francisco Javier Clavijero Botanic Garden
    Research article The role of the Francisco Javier Clavijero Botanic Garden (Xalapa, Veracruz, Mexico) in the conservation of the Mexican flora El papel del Jardín Botánico Francisco Javier Clavijero (Xalapa, Veracruz, México) en la conservación de la flora mexicana Milton H. Díaz-Toribio1,3 , Victor Luna1 , Andrew P. Vovides2 Abstract: Background and Aims: There are approximately 3000 botanic gardens in the world. These institutions cultivate approximately six million plant species, representing around 100,000 taxa in cultivation. Botanic gardens make an important contributionex to situ conservation with a high number of threat- ened plant species represented in their collections. To show how the Francisco Javier Clavijero Botanic Garden (JBC) contributes to the conservation of Mexican flora, we asked the following questions: 1) How is vascular plant diversity currently conserved in the JBC?, 2) How well is this garden perform- ing with respect to the Global Strategy for Plant Conservation (GSPC) and the Mexican Strategy for Plant Conservation (MSPC)?, and 3) How has the garden’s scientific collection contributed to the creation of new knowledge (description of new plant species)? Methods: We used data from the JBC scientific living collection stored in BG-BASE. We gathered information on species names, endemism, and endan- gered status, according to national and international policies, and field data associated with each species. Key results: We found that 12% of the species in the JBC collection is under some risk category by international and Mexican laws. Plant families with the highest numbers of threatened species were Zamiaceae, Orchidaceae, Arecaceae, and Asparagaceae. We also found that Ostrya mexicana, Tapirira mexicana, Oreopanax capitatus, O.

    ALEJANDRA GUZMÁN-LUNA1, CRISTINA MARTÍNEZ-GARZA2* Botanical Sciences 94 (4): 757-773, 2016 Abstract Background. Minimal restoration intervention includes actions to stop disturbance so natural succession DOI: 10.17129/botsci.659 may take place whereas maximal intervention involves the establishment of plantings. Questions. To evaluate the success of minimal versus maximal restoration intervention, the performance of recruits and transplants was assessed. To this end, performance of 15 native tree species was predicted using life-history, their origin (recruits or transplants) and 12 plant functional traits. Study site and years of study. This study was carried out in pastures at Los Tuxtlas, Veracruz, Mexico in 5 years old restoration settings. Methods. Pioneer and non-pioneer species were planted in 16 30 × 30 m plots whereas natural recruitment was evaluated in plantings and at eight additional fenced plots. Results. Overall 15 species recruited or planted, pioneers had higher performance than non-pioneer. Trans- plant shock in terms of survival and height growth rates was overcome after 5 years probably as a result of increases in diameter growth rates. Conclusions. Tree species are divided in three groups to give recommendation for restoration: (1) Species in the Good recruiters group do not need to be transplanted; if seed sources are not close, we recommend direct seeding (i.e., Albizia purpusii, Cedrela odorata, Cecropia obtusifolia). (2) Species in the Good transplants group show very low or nil recruitment; they should be transplanted (i.e., Ochroma pyramidale, Ficus yopo- nensis, Cojoba arborea). (3) Species in the Poor transplants group should be transplanted but once a canopy has developed (i.e., Amphitecna tuxtlensis, Brosimum alicastrum, Bernoullia flammea).

    Legume-feeding Lepidoptera of the Florida Keys: potential competitors of an endangered lycaenid butterfly Sarah R. Steele Cabrera1,2,*, James E. Hayden3, Jaret C. Daniels1,2, Jake M. Farnum4, Charles V. Covell Jr.1, and Matthew J. Standridge1 Abstract Two Fabaceae in the Florida Keys, Pithecellobium keyense Coker and Guilandina bonduc Griseb., have been of interest because they are the larval host plants for the endangered Miami blue butterfly (Cyclargus thomasi bethunebakeri [Comstock & Huntington]; Lepidoptera: Lycaenidae). As a part of ongoing research and conservation for this butterfly, wild host plant material has been periodically collected in order to supplement a captive colony ofC. t. bethunebakeri located in Gainesville, Florida, USA. In examining this plant material, 26 lepidopterans were detected, includ- ing several host records, a new continental record, and 2 likely undescribed species, 1 Aristotelia (Gelechiidae) and 1 Crocidosema (Tortricidae). Our results expand the geographic, life-history, and taxonomic understanding of lepidopteran herbivores that use P. keyense and G. bonduc in South Florida. Key Words: Pithecellobium keyense; Guilandina bonduc; Fabaceae; herbivory Resumen En los Cayos de Florida, habitan dos especies de plantas hospederas críticas para el ciclo de vida de la mariposa Miami blue (Cyclargus thomasi bethunebakeri [Comstock y Huntington]; Lepidoptera: Lycaenidae), la cual está en peligro de extinción.

Vélez3, Santos A. Henríquez4, and Jorge A. Santiago-Blay5 Abstract: The Citrus Fruit Borer, Gymnandrosoma aurantianum Lima, 1927 (Lepidoptera: Tortricidae), is a major pest of Neotropical fruits. We report this species for the first time from Melicoccus bijugatus Jacquin (Sapindaceae), commonly known in Puerto Rico as quenepa. Distinguishing features for the three species of Gymnandrosoma reported for Puerto Rico, G. aurantianum, G. leucothorax, and G. trachycerus, are given. Key Words: Melicoccus bijugatus, new host plant, Citrus Fruit Borer, Gymnandrosoma aurantianum, Arthropoda, Hexapoda, Lepidoptera, Tortricidae Tortricidae are a large (approximately 10,000 described species) and economically important insect family in the order Lepidoptera (Beccaloni et al. 2003; Brown 2005; Brown et al. 2008; Baixeras et al. 2010). Gymnandrosoma is a mostly Neotropical genus of oleuthreutine tortricid currently containing nine species, including G. gonomela (Lower, 1899) from Australia (Horak 2006) and G. junina Razowski and Wojtusiak 2010 from Perú. According to Adamski and Brown (2001), Gymnandrosoma adults have the following four synapomorphies that uniquely distinguish them from those of other putatively closely related taxa in the Ecdytolopha group of genera, such as Ecdytolopha, Thaumatotibia, Pseudogalleria, and Cryptophlebia, of the tribe Grapholitini: 1) forewing 1.95- 2.08 longer than wide (Table 4 in Adamski and Brown 2001 and Figure 1, this work), other genera have a larger l/w ratio; 2) male antennae with basal fourth slightly flattened, bearing conspicuously long sensory setae (“cilia” sensu Adamski and Brown 2001) throughout (Figure 58 in Adamski and Brown 2001 and Figure 2A, arrows, this work), 3) male hind tibia with dense, modified, 1 Submitted on August 15, 2012.

Abstract Aim of the study: The aim of this work was to isolate consortia of arbuscular mycorrhizal fungi (AMF) associated to Liquidambar styraciflua in soils of the Santa Marta Mountain in Veracruz, and to select highly effective mycorrhizal consortia on promoting the growth of four tree forest species with economic and ecological importance. Area of study: Santa Marta Mountain, inside the buffer area of the Los Tuxtlas Biological Reserve in Veracruz (México). Materials and methods: Ten composite samples of rhizosphere soil were collected from L. styraciflua trees of 13-15 cm DBH (diameter at breast height). Roots were fixed in FAA solution to determine the mycorrhizal colonization percentage, the abundance of morphospecies, and its effectiveness in promoting the growth of L. styraciflua, Terminalia amazonia, Cordia alliodora, and Cojoba arborea. Soil physical and chemical characteristics were also analysed, and soil type recognition was performed with the Reference Base for Soil FAO-ISRIC World-SICS.

    CROP PRODUCTION SCIENCE IN HORTICULTURE SERIES Series Editor: Jeff Atherton, Professor of Tropical Horticulture, University of the West Indies, Barbados This series examines economically important horticultural crops selected from the major production systems in temperate, subtropical and tropical climatic areas. Systems represented range from open fi eld and plantation sites to protected plastic and glass houses, growing rooms and laboratories. Emphasis is placed on the scientifi c principles underlying crop production practices rather than on providing empirical recipes for uncritical acceptance. Scientifi c understanding provides the key to both reasoned choice of practice and the solution of future problems. Students and staff at universities and colleges throughout the world involved in courses in horticulture, as well as in agriculture, plant science, food science and applied biology at degree, diploma or certifi cate level will welcome this series as a succinct and readable source of information. The books will also be invaluable to progressive growers, advisers and end-product users requiring an authoritative, but brief, scientifi c introduction to particular crops or systems. Keen gardeners wishing to understand the scientifi c basis of recommended practices will also fi nd the series very useful. The authors are all internationally renowned experts with extensive experience of their subjects. Each volume follows a common format, covering all aspects of production, from background physiology and breeding to propagation and planting, through husbandry and crop protection to harvesting, handling and storage. Selective references are included to direct the reader to further information on specifi c topics. Titles available: 1. Ornamental Bulbs, Corms and Tubers A.R.
