Species 2, endemic. 
R. Staudtii, Pax in Engl. Jahrb. xxiii. 532, and in Engl. Pflanzenr. Euphorb.- 
Cluytiexw, 49, has hermaphrodite flowers, and is therefore not Euphorbiaceous. It 
seems to belong to Anacardiacee, of which order it may represent a new genus. 
Leaflets sessile, acuminate, glabrous when mature; 
stamens 10 5 5 : 5 - : A - 1. R. africanum. 
Leaflets stalked, obtuse, stellate-puberulous or tomentellous 
on both surfaces when mature; stamens 15-16. - 2. R. Rautanenii.
