Mrs. D. van der Bijl, of Abraham’s Kraal, in the Beaufort West District, who has contributed several interesting plants we have figured, sent us specimens in 1919, which flowered at the Division of Botany, Pretoria, this year. It was figured in a coloured plate by Masson in 1796, and our present Plate is the first to be produced since then. A pencil drawing of a portion of the flower, the corona and the pollinia, accompanied Brown’s original description, and while our specimen differs in some minor points from the drawings, we have no hesitation in referring it to the same species. The flower is rather handsome, and devoid of the objectionable smell usually associated with the members of the tribe _Stapelieae_.
