Genera | |
The family Apodanthaceae comprises about 10 species[1] of endoparasitic herbs. They live in the branches or stems of their hosts (as filaments similar to a fungal mycelium), emerging only to flower and fruit. The plants produce no green parts and do not carry out any photosynthesis (that is, they are holoparasitic). There are two genera: Pilostyles and Apodanthes.[2] A third genus, Berlinianche, was never validly published.[3] Mitochondrial and nuclear DNA sequences confidently place the Apodanthaceae in the Cucurbitales, where they also fit well in terms of their flower morphology.[4] The native range of Apodanthes is restricted to Central and tropical South America,[5] while Pilostyles has a much wider though disjointed native range, encompassing many countries in tropical and subtropical America, a section of Africa from Gabon to Tanzania and down to Zimbabwe, as well as Turkey, Iran, Iraq, and Western Australia.[6]
