Habitat : NATAL : In open ground all over the Colony. Northdene, 700 feet 

 alt. March, Wood. 



Drawn and described from specimens gathered near Durban, March, 1900. 



A common plant in grassy places all over the colony, but most common in the 

 coast districts, the pubescence is somewhat variable, and the young leaves are 

 often, perhaps always silky silvery. This plant and R. Woodii, "Schinz, are the 

 only two species of the genus known to us in Natal having a quite erect habit, all 

 the remainder being climbers or creepers. It has no known useful properties, and 

 we cannot learn that the natives have any distinctive name for it. The genus in- 

 cludes about 80 species, all being natives of warm climates.
