''. Linnaeus did not explain the etymology but later explanations stated that the name ''Ceropegia'' was from the Greek word ''keropegion'' κηροπηγɩον. This means ''candelabrum'' in Latin, which has a broader range than the modern word - "a candlestick, a branched candlestick, a chandelier, candelabrum, or also lamp-stand, light-stand, sometimes of exquisite workmanship". An alternative explanation for the name was given later by William Jackson Hooker in 1830 in ''Curtis's Botanical Magazine'' in the description of ''

'': "From '' κηρός'', wax, and '' πηγή'', a fountain, in allusion to the delicate, waxy umbels of some species". However, four years later Hooker gave the etymology in the description in the same periodical of '' Ceropegia lushii'' as "remarkable for the peculiar shape of its flowers, frequently arranged in umbels, hence its name κηροπηγɩον, a candelabrum, or lamp-stand". They have many common names including lantern flower, parasol flower, parachute flower, bushman's pipe, string of hearts, snake creeper, wine-glass vine, rosary vine, and necklace vine. ''Ceropegia'' species are traded, kept, and propagated as ornamental plants.Ollerton, J., Masinde, S., Meve, U., Picker, M., & Whittington, A. (2009)

s most often fused at the tips, forming an umbrella-like canopy, a cage, or appendage-like antennae. The flowers of this genus are adapted for pollination by flies. A great diversity of fly species are associated with ceropegias. The flowers are often inflated and fused at several points, forming a cage. Flies become momentarily trapped inside, accomplishing pollination as they move about.

Classification

The genus ''Ceropegia'' belongs to the subfamily Asclepiadoideae (milkweeds) within the family Apocynaceae. Species of this genus bear similarities to the carrion flowers or stapelias. There are at least 420 known species. More are being discovered and described regularly. Herbert F. J. Huber: Revision of the genus Ceropegia. In: Memórias da Sociedade Broteriana, Volume 12, 1957, S.1-203, Coimbra They are distributed throughout most of sub-Saharan Africa and Madagascar to the Arabian Peninsula, southeast Asia, the Canary Islands, the tropical Pacific, and Australia.
