species leads to the belief that it has been misinterpreted and that to it 
should be referred E. macrophylloides Robinson, Proc. Am. Acad. liv. 
249, 340 (1918). The only two collections of the species known to the 
writer are as follows: at Caracas, Vargas (DC., phot. Gr.), and at 
Sanchorquiz, Eggers, no. 13,413 (U.S.). The localities, both in the 
Federal District of Venezuela, are not far apart. 
The species has been reported twice from Colombia, namely by Klatt 
in Engl. Bot. Jahrb. viii. 36 (1887), on the basis of Lehmann’s no. 938 
Hy near Popayan, and by Heering, Mém. Soc. Neuchat Sci. Nat. v. 
420 (1913), on Mayor’s no. 392, from near Medellin. The writer has
