324 FIELD MUSEUM or NATURAL HISTORY BOTANY, VOL. II 



The species is well marked on account of the strongly discolorous 

 leaves, which are densely tawny pubescent on the under surface, and by 

 the decurrence of the petioles on the stem thus causing the younger 

 branches to be subancipitally angled, or strongly keeled, hence the 

 specific name.
