Obs. This species, which has a superficial resemblance 

 to CcplxilnzieJla divaricata (Sm.) is distinguished from it by 

 its monoicous inflorescence and from the other known Afri- 

 cain species by its entire leaf-margins. 



Collected first at Umpumulo, Natal, S. Africa, March 

 1867 by the Norwegian missionary Mr. Borgen and recog- 

 nised by the late C. F. Austin, who with his keen eye de- 

 tected a few stems growing with Dicranélla Borgeniana Hpe. 

 and named it Jung. Kiaeri in Bull. Torry Bot, Club vol. VI 

 no. 3 p. 18 n. 5 (1875.) 



His description of the leaves „minute eroso-serrulata" 

 only applies to the young shoots, as the original specimens 

 which I have, are as figured.
