A delicate species with habit of the Costa-Rican E. sideritidis 
Benth. but more slender, with leaves more pubescent, only half as - 
long, and crenate instead of incisely serrate. The related E. Sinelairi 
Benth of Costa Rica and Panama has broadly ovate leaves with 
relatively longer petioles. The Ecuadorian E. Iloense Hieron., of 
somewhat similar habit and inflorescence, has longer but much fewer- 
flowered heads, larger leaves, ete.

about 3-4-seriate, with mostly 2 pale ribs and 3 green nerves; the
