Along small streams at low altitudes. 
A species strongly characterized by its midribs, nerves, and 
reticulations on the lower surface of the leaves being densely 
cobwebby-villous and, hence, very conspicuous, as well as by its 
long-peduncled inflorescences. It belongs in the general group 
with Argostemma urticifolium King and A. teysmannianum Mig.
