Seed larger than minute; not bowl shaped; not nutlike; without winglike beak; without caudate appendage(s); at maturity with food reserves; with endosperm; without canavanine. Sarcotesta absent. Testa present; without fleshy or leathery layer over hard layer; without glands; without bristles; without wings; without collar; without operculum; colored; monochrome; not becoming mucilaginous when wetted. Endosperm scant; without fatty acid containing cyclopropene; without apical lobes; without chlorophyll; without isodiametric faceted surface; without odor.
Embryo differentiated from food reserve; well developed; partially filling testa (with food reserve); at one end of seed not extending into a depression or cup; axile and centric; straight; without coleorhiza; without simmondsin; with cotyledons containing oils; without stomata; not green; with 2 or more cotyledons (assumed). Cotyledons 2 (assumed); equal in size; not punctate dotted.
Distribution
New World. Middle America (Nicaragua to Panama).
Notes
Gomez-Laurito & Gomez P. (1991): "Fruit drupaceous, 1-seeded. Embryo oily with straight cotyledons. Ovary inferior, bicarpellate, including perianth tube". Gomez-Laurito & Gomez P. (1989): " Fruit asymmetrical, unilateral somewhat swollen on 1 side, ovate, base rounded, apex acute, drupaceous, ca. 7 cm. long, green. mucilaginous; endocarp very hard, longitudinally furrowed; endosperm scanty; 1 seed per fruit. "The dry, hardened fruits bear a faint resemblance to those of Coryllus L., and, when we frist saw a vegetative specimen, we thought of Carpinus L. which reaches northern Nicaragua".

We advise against extracting comparative information from the descriptions. This is much more easily achieved using the DELTA data files or the interactive key, which allows access to the character list, illustrations, full and partial descriptions, diagnostic descriptions, differences and similarities between taxa, lists of taxa exhibiting or lacking specified attributes, and distributions of character states within any set of taxa. See also Guidelines for using data taken from Web publications.
