SCHOMBURGK’S GUIANA PLANTS. 213 
olive-shaped; in Licania, narrow-obovate, oblong, clubshaped, 
or even linear. The fruits of Parinarium, and of Couepia, are 
already sufficiently described; that of Moquilea is unknown.— 
Acioa of Aublet appears to have many of the characters of 
Couepia, but, judging from a very indifferent specimen, has 
not the habit, and I have no means of examining the flowers. 
Thelyra of Du Petit Thouars, and Prinsepia of Royle, are 
unknown to me. "
