|Scientific Name:||Begonia furfuracea|
|Red List Category & Criteria:||Endangered B2ab(iii) ver 3.1|

This epiphytic species of Begonia sect. Tetraphila is specific to lower cloud forest. It was recently revised by J.J.F.E. de Wilde (2002). He cites evidence that the subpopulation on Bioko may have been effected by cultivation of cocoa, coffee and bananas, for which most of the original vegetation below 700 m was cleared, however, this species occurs above that altitude so this threat may not apply. However, degradation of the forest habitat there is suspected since there is good road access (Q. Luke pers. comm. to Cheek 2014). Begonia furfuracea was first collected in Bioko by Mann in 1860, recollected many decades later by Mildbraed and then relatively recently (c. 1960s) by Sanford and Carvalho. The Cameroonian subpopulation first came to light in the 1970s at Kondo, 40 km northwest of Bamenda (Letouzey 14186) an area where most forest has now been extirpated. The species probably now has its stronghold at Kupe-Bakossi. De Wilde cites three collections from the area (de Wilde 2002: 89). To these can be added a further five (Cheek et al. 2004). The conservation assessment of this species in Cheek et al. (2004) was Vulnerable B2ab(iii), but in Onana and Cheek 2011 we adopted a better understanding of the IUCN concept of location and accepted five locations, for an assessment of Endangered (area of occupancy 28 km² and continuing decline in the extent and quality of the habitat due to expanding agriculture). The Bata location was newly added, based on a determination by Plana but is suspect since the altitude is near sea-level and the location is disjunct: the identification needs checking.
|Previously published Red List assessments:|
|Range Description:||The species has been recorded from Equatorial Guinea (Rio Muni (one collection); Bioko (four collections, two sites)); and Cameroon (Bamenda, Kondo (one collection), Mt Kupe and the Bakossi Mts (eight collections)).|
Native:Cameroon; Equatorial Guinea (Bioko, Equatorial Guinea (mainland))

Population size is not known but is thought to be in decline.
|Current Population Trend:||Decreasing|
|Habitat and Ecology:||This epiphytic species grows in evergreen forest, 1,000-1,330 m alt.|
|Continuing decline in area, extent and/or quality of habitat:||Yes|
|Major Threat(s):||Habitat destruction occurs at its known sites in Bakossi due to forest clearance for small-holder agriculture (M. Cheek pers. obs.). There is no data on the Bioko sites, but habitat degradation is suspected. In the Bamenda Highlands 96.5% of forest was estimated as lost (Cheek et al. 2000) and that which survives is disappearing fast (50% lost 1988-2003 in the Dom area fide Baena in Cheek et al. 2010).|
|Conservation Actions:||Yearly monitoring of plants to assess population trends is advisable. An attempt should be made to rediscover and assess the status of the Bioko subpopulation.|
