Couratari Calycina
''Couratari'' is a genus of trees in the family Lecythidaceae, first described as a genus in 1775. They are native to tropical South America and Central America. They are large trees, often rising above the rainforest canopy. The leaf, leaves are evergreen, alternate, simple, elliptical, up to 15 cm long, with a serrate to serrulate margin. Vernation lines parallel to the midvein are often visible - a very unusual characteristic. The fruit is 6–15 cm long, and roughly conical. A central plug drops out at maturity, releasing the winged seeds to be dispersed by wind. The fruit of ''Cariniana'' may be distinguished from those of ''Couratari'', as the former have longitudinal ridges, whereas the latter bears a single calyx-derived ring near the fruit apex.Davidse, G., M.
