Abstract

The history and nomenclatural problems of the name Limbella are reviewed, the correct citation of the generic name being Limbella (C. Muell.) Broth. The genus consists of two species, L. tricostata (Sull.) Broth. and L. fryei (R. S. Williams) Ochyra which are described. L. tricostata is endemic to the Hawaiian Islands and L. fryei to Oregon on the Pacific coast of North America. Sporophytes are recorded for the first time in L. tricostata. The family relationships of Limbella are discussed and it is placed in the Thamnobryaceae, close to Thamnobryum.
