id please for parasite
Hi folks,
A few years ago I found this plant near Ibadan, Nigeria, apparently parasitic (since only non-chlorophyllous parts seem to come above the soil surface). It was in a mixed orchard of Theobroma cacao and Cola nitida, so I presume it was parasitizing the roots of one or the other, although there were plenty of weed species present as well, and I guess it could have been attacking one of them. Any ideas about its identity would be appreciated.

That appears to be it. A family with which I'm not at all familiar. |

That appears to be it. A family with which I'm not at all familiar. Probably relatively few botanists are very familiar with this family. They are definitely among the oddest parasitic angiosperm families; many members superficially seem more reminiscent of fungi than of vascular plants. At least _Thonningia_ has those showy red bracts, so its inflorescences appear more flowerlike than fungoid. Some nice photos of Thonningia, by the way! cheers |
