 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 urtici folium King and A. teysmannianum Miq.
