Linnaeus named⁹ the genus Ceropegia in 1737 in his Genera plantarum. Linnaeus referred to the description and picture of a plant in the Horti Malabarici as the plant for which the genus was created. In 1753 he named this as Ceropegia candelabrum.
Above we have the iconotype of the Indian plant that Linnaeus named as Ceropegia candelabrum in 1753, as depicted¹³ in the Horti Malabarici of Henricum Rhede (or Reede) tot Drakestein published in 1689. The candelabrum bit gives it away when you see the way the flowers are arranged. Of course, some of you born after the invention of electric light may not have seen any candelabra or chandeliers.
There have been two possible explanations of the origin of the word Ceropegia. Linnaeus never explained it, as far as I know.
