Afrothismia ugandensis nom. nov. (Afrothismiaceae), Critically Endangered and endemic to Budongo Central Forest Reserve, Uganda
The fully mycotrophic (or mycoheterophic) Afrothismia ugandensis Cheek nom. nov. (Afrothismiaceae), formerly described as A. winkleri (Engl.) Schltr. var. budongensis Cowley from the Budongo Forest in Western Uganda, is renamed, redescribed and illustrated. This change in status is supported by eight newly elucidated, qualitative, morphological, diagnostic characters despite the overall similarity with A. winkleri, a species restricted to Cameroon and Gabon. Afrothismia ugandensis is remarkable in the genus for occurring in semi-deciduous (not evergreen) forest and for having ellipsoid or ovoid (vs globose) root bulbils. It has only been recorded twice, first in August 1940, and most recently in June 1998, despite targeted searches in recent years. In both 1940 and 1998, only single individuals appear to have been detected. A single site for the species is known with certainty. It is here assessed as Critically Endangered [CR B2ab(iii); D1] using the IUCN categories and criteria. A. ugandensis is threatened by forest degradation and clearance due to illegal, selective, small-holder logging for firewood and charcoal, timber and limited agriculture.
