The species now described was discovered by Mr. Dinter 
near Barmen in German South-west Africa (Dinter, n. 1502). 
Living plants sent by him to the late Sir Thomas Hanbury 
at La Mortola flowered there in July, 1907, and again in 
November, 1908, when the specimens from which our 
drawing was prepared were forwarded to Kew. The plant 
calls for very dry treatment, more especially in winter, when 
little or no water should be given to it.
