The plant figured as Ceropegia trichantha in Fl. Reipubl. Popularis Sin. (63: 573, t. 218, 1977) is a form of C. longifolia Wallich. Huber (Mem. Soc. Brot. 12: 54. 1957) included Ceropegia trichantha in the Indian C. lucida Wallich subsp. lucida. Material so named is extremely variable and probably represents more than one taxon.
