Hydnora is a genus of subterranean holoparasitic herbs found in arid and semiarid regions of Africa, Madagascar, and the southwestern part of the Arabian peninsula. Results from field and herbarium studies suggest the genus consists of four or five species, although more than 12 have been described. The recent rediscovery of H. triceps, a plant that had remained uncollected for a century, supports the need for additional field work. Taxonomic research has been impeded by a paucity of…

Parasitic plants pummel pavement—Hydnora abyssinica (Hydnoraceae)

Very little is known about the interaction between host and parasite and it is possible that the parasite supplies the host with water in return for nutrients, in which case the relationship is more commensal than parasitic.

At least eleven synonyms or subspecific varieties of H. abyssinica are described in the literature, all from east or southern Africa, and these synonyms are discussed in light of new observations of morphology including tepal margin ornamentation.
Tiputinia foetida, a new mycoheterotrophic genus of Thismiaceae from Amazonian Ecuador, and a likely case of deceit pollination
- Biology
- 2007
It is hypothesize that Tiputinia evolved its scent and unusual floral morphology as a deceit pollination mechanism to attract flies or other pollinators down into the floral tube, where they would first contact the stigma, lay eggs on the inner, horizontal ridges of the tube, and finally contact the latrorse anthers as the insects emerge from the flower.
Structural attributes of the hypogeous holoparasite Hydnora triceps Drege & Meyer (Hydnoraceae).
- Environmental ScienceAmerican journal of botany
- 2007
The vegetative body of H. triceps was found to consist of a rhizome with a thickened root-cap-like structure that covered a vegetative shoot apical meristem, and "Haustorial roots" or bumps on the surface of the vegetativeBody were exogenous, contained meristems and were the origins of vegetative branching, budding, and haustoria.
