1. Clastobryopsis robusta (Brotherus) M. Fleischer

[ Sematophyllaceae]

This is widespread Malesian moss species, reported here for the first time from Mindanao, is characterized by having many expanded, somewhat complanate, and attenuated branch terminals that produce plenty of filamentous propagules in leaf axils. This species is rather large in plant size among its congeners and can be recognized further by having broad, decurrent leaf bases, recurved upper leaf margins with strong marginal teeth, and, a heterophylloid alar organization (cf. Tan and Jia 1999). In the Philippines, Clastobryopsis robusta, which is an epiphyte of small branches in forest canopy, is also widespread on Luzon Island and islands of the Visayan group.
