- This species has the habit and somewhat the general appear- 
ance of Psychotria sarmentosa Blume but is not closely allied 
to that species as the albumen is not at all ruminate. It is well 
characterized by its slender stems; its membranaceous, slenderly 
nerved leaves, the reticulations being entirely obsolete; and its 
oblong-obovoid, prominently sulcate fruits and prominently sul- 
cate seeds.
