This is closely allied to R. Zeyheri and has been so named by Dr. Schlechter, 
but the very differently shaped sepals, shorter corona-lobes, longer (although 
minute) pubescence and different geographical area well distinguish it. Bur- 
chell’s specimens have narrower leaves and fewer and rather smaller flowers than 
the typical Transvaal plant, but I can find no other difference. 
8. R. velutina (Schlechter in Engl. Jahrb. xx., Beibl. 51, 12) ; 
plant 3-5 in. high, with 1 or more ereet branching stems from the
