Planchon described (Prod. Apocyn. 108-110) the follicles and seeds of a plant 
collected by Ballay in Gaboon and supposed to be a Wrightia. The follicles are 
said to reach more than 2 ft. in length, and to be slender, brown or blackish, striate 
without, yellow within ; the seeds are described as being lanceolate, acute at the 
» attenuate ut the apex into a plumose awn about 5 lin, long, pale brown and 
prominently striate, enclosing a scanty endosperm and an embryo, the cotyledons 
of which are complicate and § shaped in cross section. The presence of a plumose 
terminal awn excludes this plant from Pleioceras as well as from Wrightia, and 
the folding of the cotyledons from Strophanthus.
