Flowers white. _Perianth-tube_ subcylindric, glabrous; segments 1·7 cm. long, linear, obtuse. _Stamens_ 6; filaments subulate; anthers versatile. _Ovary_ globose, 3 mm. in diameter; style subulate; stigma minutely tricuspidate.

Cap._ vol. v. sect. i. p. 813. * * * * * This beautiful species of _Ceropegia_ is almost unique in the genus on account of the peculiar formation of the corolla-lobes. The illustration should be compared with those given on Plates 39, 44 and 143, and the striking differences will then be seen. It is closely related to _C. tristis_, Hutch. described on Plate 44, but the corolla-lobes are produced into a much longer cylindric portion and the calyx-lobes are longer. The specimen from which our illustration was made flowered in the greenhouse at the Division of Botany in July 1925, and like the other species of the genus always attracts attention owing to the peculiar shape of the flowers.
