is distinct from both Archilejeunea Spruceajia and Lejeiinea flor- 

 entissinia. It agrees, however, in all essential respects, with 

 Arcliilejeunea Sellozviaiia Steph., a species which was also orig- 

 inally described from Brazilian specimens. It therefore becomes 

 necessary to reduce this latter species to. synonymy as indicated 

 abov^e.

Apparently on trees. Known only from Cape Colony, the 

 type-locality. Judging from the original specimens in the Lin- 

 denberg herbarium, this species is dioicous ; in other respects it 

 shows a close approach to L. nnciloba.
