Meve, U. 1995. Cytological and morphological differentiation in Carallurna burchardii (Asclepiadaceae). — Nord. J. Bot. 15: 459–467. Copenhagen. ISSN 0107–055X. Caralluma burchardii is revised based on detailed investigations of vegetative and floral morphology, as well as chromosome numbers. The species is now divided into two taxa, the dodecaploid ssp. burchardii , an endemic of the Canary Islands, and ssp. rnaura , a hexaploid from the west coast of Morocco. The high ploidy levels involved, the highest known in the Asclepiadaceae, are discussed in conjunction with biogeographical aspects.
