Bothalia: African Biodiversity & Conservation (Sep 1991)
Studies in the genus <i>Riccia</i> (Marchantiales) from southern Africa. 22. R. rubricollis, now validated, typified and described
Abstract
Riccia rubricollis is a very rare endemic species, only known from a few collections by Duthie at Knysna. Unfortunately she and Garside did not publish anything on it, and Arnell's (1963) description has neither a Latin diagnosis nor was a type specimen cited. These omissions have now been rectified here, following the recent rediscovery of Duthie's collections at BOL.
