was rediscovered in its type locality. Trichosporum asclepioidee 
Elm. is here described as new, and was occasionally seen as 
an epiphyte in the rainy forests. This region is also the 
topotype of Dichrotrichum glabrum Copel. My Dichrotrichum clark- 
ei has several times been noticed as a heavy succulent epi- 
phyte in these same forests. Dichrotrichum calelanense Elm. was 
discovered in the moss laden elfinwoods on the summit of 
mount Calelan. Only two of the twelve species of Cyrtandra here 
listed were collected on Sibuyan island, the balance on mount 
Apo; and all of them are herein described as new, although 
a few of them are only critically distinguished from other 
allied species or groups of closely related species.
