March 27, 1915] Two HuNpnED Twenty Six New Sprecies—I 2667 
Type specimen number 13710, A. D. E. Elmer, Cabad- 
baran (Mt. Urdaneta), Province of Agusan, Mindanao, Sept- 
ember, 1912. 
Discovered in the humid moss laden and rigid woods 
among the summit peaks of mount Urdaneta at 6000 feet 
altitude. ''Balibadon'"' is its Manobo name. 
This pretty genus is always met in our alpine regions by one 
or two species and nowhere are the individual plants common. 
Of this species as well as of Dichrotrichum calelanense Elm. 
and of Dichrotrichum biflora Elm. I found but one plant.
