When time and funding permit, each flower (each plant species) will have its own page, and its own PDF, and eventually its own PPT so that professors and students have plenty of material on Guatemala (and Honduras, etc) to study.

Characteristics of the genus Cojoba Britton & Rose and the species Cojoba arborea |
Bibliography on Cojoba sp. and Cojoba arborea Species description and general information Cojoba Britton & Rose is a genus of the family Fabaceae and the subfamily Mimosoideae and is a member of the tribe Ingeae (Santana, 2015). Sometimes the word “Cojoba” lets to confusion since it refers to several species like Swietenia mahagoni (L.) Jacq. and Piptademia peregrine (L.) Benth. P. peregrine was used by the Taino Indians of the Bahamas in a ceremony called Cohoba, in which they inhaled a hallucinogenic substance obtained by pulverizing the seeds of the tree (Santana, 2015). Description of Cojoba arborea This species is a fast-growing tree that reaches more than 40 m in height and 50-80 cm in diameter in the natural forest. Straight trunk without buttresses and latex free (Red de Viveros de Biodiversidad, n.d.). The foliage is shiny and the bark is brown or grayish brown and smooth and sometimes has small, longitudinal fissures. The inner bark is pinkish and has bitter taste. The leaves are compound, bipinnate, with 10 to 18 pairs of pinnae, opposite or semiopposite, each with 20 to 40 pairs of opposite, sessile pinnules. The flowers are in pedunculate axillary heads in the upper leaf axils. The calyx is green and tubular and the corolla, whitish or creamy (Vozz, 2002). The seeds of this species are dispersed by parrots an parakeets but mostly by gravity.
The species distribution extends from southern Mexico, along the East Coast of Central America and Cuba, Jamaica, Puerto Rico, Colombia, Bolivia, Peru and Brazil (Carvalho et al., 2021). It’s a typical tree of the tropical rain forest of the coastal lowlands with clay or sandy alluvial soils, it grows well at elevations up to 1200 m (Vozz, 2002). C. arborea has three varieties distributed in Latin America: angustifolia, arborea and cubensis (Ferreira et al., 2021). Taxonomy
Uses of the species The wood of Cojoba arborea is odorless and tasteless an it can be used for flooring, ceilings, ornament work, furniture, wheel hubs, rollers, brush backs, mills, and railroad ties. Wood can also be used for firewood, charcoal, fence posts, and tool handles as well in the manufacture of musical instruments due to its excellent quality (Carvalho et al., 2021). The species is also used as an ornament and shade tree (Vozz, 2002). Some studies have proven that C. arborea presents anti-inflammatory activity along with other species such as Jacaranda arborea, Mikania cordifolia and Bauhinia cumanensis (Hirukawa et al., 2020).
