1. E.ueprocernatum DC. (see p. 278). To this species the writer 
would refer E. tequendamense, vars. glanduloso-pubescens and glabraia 
Hieron. in Engl. Bot. Jahrb. xxix. 6 (1900). Examined in fragments 
kindly supplied to the Gray Herbarium some years ago by the manage- 
ment of the Royal Botanical Garden at Berlin, these varieties are 
found to differ but slightly and in degree only, either from each other 
or from authenticated material of E. leptocephalum. On the other 
hand they may be distinguished from the typical Colombian form of 
E. tequendamense (= E. subscandens Hieron.) in having more slender 
fewer-flowered heads, straight pedicels, and leaves much more at- 
tenuate at the base. To E. leptocephalum the following Ecuadorian 
material may be referred. PicuincHa: Quito, Jameson (Gr.); 
Niebli, Sodiro, no. 6/26 (Berl., fragm. Gr.). PROVINCE NOT INDICATED:
