 0. Sodiroi Hieron. but differing in its firmer-textured broader leaves 

 which are subtruncate at base and more coarsely crenate-serrate.

E. ARCUANS Robinson, Proc. Am. Acad. liv. 237, 288 (1918). The 

 type of this recently described species, namely Triana, no. 1191 (K.), 

 though believed to have come from Colombia, was unaccompanied 

 by data as to the exact locality of collection. Happily the species 

 has now been rediscovered by Pro. Ariste-Joseph, being represented 

 by his no. A250 (Gr.) from Guadalupe, near Bogota. This specimen 

 recently received from the U. S. National Museum proves to agree 

 in all features very closely with the original plant of Triana. The 

 species may therefore be definitely located as occurring in the moun- 

 tains near Bogota in the Department of Cundinamarca.
