5. Lejeunea (Micro-Lejeunea) gracillima Mitt. 



Growing parasitically on larger Lejeuneae and Plagio- 

 chilae, agrees exactly with original specimens of Mitten from 

 Point Galle, Ceylon. 



Near to Micro-Lejeunea ulicina Tayl. but differs in its 

 smaller size and more erect leaves.

 diam., leaves .175 mm high X .11 mm broad, .16 X .1, .15

6. Radula commutata G. 



$ plants of this dioicous species with erose leaves and 

 imperfect perianths. I can detect no character of sufficient 

 value to separate it from the European form. Radula 

 Capensis Steph. is no doubt a nearly allied species, to judge 

 from description, but the apex of the lobule is obtuse not 

 acute, and the leaves not erose or at least no mention is 

 made of the fact. 

 Hab. On trees near Umpumulo.
