Type specimen 8396, A. D. E. Elmer, Baguio, Province 
of Benguet, Luzon, March, 1907. This was only once or 
twice seen in a jungle on Mount Santo Tomas at 2500 
meters. According to de Candolle’s Prodomus it belongs to 
section Hebephora a small group of doubtful relation to. Pluch- 
ea and Blumea. Its nearest ally is P. scabrida DC. from 
which our specimen ean be recognized by the incised, more 
pubescent leaves.
