Notes

Hammel & Zamora (1993): "Fruit ovoidovoid:
3D shape—ovate
, exocarpexocarp:
outer layer of fruit wall or pericarp, if divided into layers; note here used synonymously with epicarp
coriaceouscoriaceous:
texture—leathery
to woodywoody:
texture—consisting mainly of indurate lignified tissues, characteristic of or resembling wood
, irregularly rupturing and falling away to expose 2 horny endocarps, 1 nearly completely surrounding the seed, the other usually empty and smaller, these also falling away, the larger taking on the shape of a snail shell".
