A very curious unrecorded species, now first introduced from the Cape of Good Hope. The masterly description is by Mr. Brown, who has so far modified the character of the genus with respect to that defined by himself in his illustration of the Natural Order, in the ' Memoirs of the Wernerian Natural History Society,' 1 as to fit it for the reception of the species before us ; which he considers too naturally allied to the East Indian group he had originally allotted to Ceropegia to be separated.
