Weisiopsis nigeriana (Pottiaceae, Bryophyta) new to Australia, with perennating rhizoids

摘要

The widely distributed but rarely collected moss Weisiopsis nigeriana (Egun. & Olarinmoye) R.H.Zander is reported as new to Australia. The world range is reviewed, and an illustration given. Unique inflated rhizoids of bulging short cells filled with dense protoplasm and oil globules are an apparent mode of survival during dry periods.
