53 or occasionally 6-8 rather deep cells; placentas on the outer v/all 

 of the cells. Cepsule (of R. albinota, the only species of which 

 fruit has been seen) obconic, with elevated suture! ridges on the 

 top and usually 9 or 10 or occasionally 6-8 valves and 06;^ Is; ex- 

 panding -keels nearly rer.chlng to the tips of the valves, closely 

 contiguous for half t'eir length then more or less diverging, with 

 acute tips and broad, pallid marginal wings; cells at first roofed 

 with thin membranous cell-Vifings, which become inrolled as the seeds 

 are shed; no plecentel tubercle. Seeds compressed-ovoid, microscop- 

 ically tuberculate. 



Species 4, natives of South -f^frica. I'he type of the genus is 

 H. albinota, N. 3. Bp. 



The name is given to coraiAenorste the service that Ivlr. V/, A, 

 Rabie, of Fauresmj.th, Orange ^Vee State, has rendered to the ^o-!anical 

 Survery of South Africa, and who from early childhood has taken 

 a active interest in South African plants, and has locelted many 

 rare species thr^t at present are knovm only from one or verelj two 

 localities, some of which are knovv'n to have been formerly comraon in 

 the region, but from overstocking the area v/ith stock have become 

 nearly extinct. 



The species of this genus are distinct, but it is difficult 

 to express in v/ords the distinctions that are easily seen with the 

 eye, especially as one never has all the plants in flovcer at the 

 same time to contrast their obvious differences. 



Key to the Species.
