concave, smooth on the outside, deeply and irregularly furrowed 
on the inside; inner divided into three or four lobes, and between 
both cotyledons a ramified fibrous mass, the remains of placenta 
and dissepiments.

Pedicel as long as calyx, which is slightly imbricate (as cor- 
rectly shown by Pierre in fig. 1, though represented as valvate in 
fig. 11), both being hispid with very short stiff hairs. Anthers 
hispid; connective witha minute blunt appendix. Ovary pubes- 
cent; style filiform, glabrous, articulate with ovary; stigma 
minute. Fruiting-calyx reflexed, as long as fruit ; pericarp thick, 
coriaceous. Seed (unripe) with coriaceous testa and some gela- 
tinous albumen; radicle short ; cotyledons thin, flat, much folded 
and crumpled ; base of pericarp on its inner face lined by a thin 
fleshy cup. Apparently ripe seeds are figured by Pierre. The 
embryo does not fill up the cavity, and fig. 16 shows the fleshy 
laciniate cup attached to the base of pericarp on its inner face, 
which Heim designates as “ cupule chalazique." 
Upon this species Heim bases two genera, viz. Vesquella upon 
Vateria acuminata, Thw., in which he also places S. oblongifolius, 
Thw.; and Sunapteopsis upon Vateria jucunda, Thw., doubtfully 
established by him as a genus. The chief charaeter of Vesquella 
is “la présence d'une cupule chalazique ou d'expansions fibreuses 
chalaziques, absolument anormales, dans le régne végétal tout
