|Scientific Name:||Begonia adpressa Sosef|
|Red List Category & Criteria:||Vulnerable B1ab(iii)+2ab(iii) ver 3.1|
|Facilitator/Compiler(s):||Lopez Poveda, L.|
This rare yellow-flowered, forest dwelling Begonia was described by Sosef in 1992, when only eight collections were known (Sosef 1994: 150), all of which were from W of Bangem in in the northern Bakossi Mts apart from three collections immediately to the north in the Bamilike (Bamboutos) area, one to the west, in the Rumpi Hills, and one immediately to the east, at Mt Nlonako. Six further collections have been made since 1995, from three sites in the Bakossi Mts one from Kupe village, one from Nyasoso, the others all from Kodmin (Cheek et al. 2004). Previously (in Cheek et al. 2004, Harvey et al. 2010) it was thought that these constituted nine locations with an area of occupancy of 14 km² calculated at 1 km² per collection, but in Onana and Cheek (2011), a wider concept of "location" was used and hence the number of locations was reduced to five, so that B. adpressa was reassessed as Endangered (five locations, area of occupancy 20 km² with 4 km² cells ). However, clarity in understanding the IUCN definition of "location" meant that the species should be treated as occurring at six locations, excluding the two sites where the species is believed extinct (in Bamboutos). Therefore the species is assessed here as Vulnerable as it has an extent of occurrence of 3,621 km2, an area of occupancy 52 km2, and there is continuing decline in the extent and quality of the habitat due to agricultural activities. Only one site occurs in a protected area, and it is thought that it does not feature in a management plan. At all other sites the species is thought to be under severe pressure and it has already been eliminated from some sites (Bamboutos-Bamileke).

Population size is not known but is thought to be in decline.
|Current Population Trend:||Decreasing|
|Habitat and Ecology:||This herb is terrestrial and it grows on rocks in montane forest; 800-1,750 m alt.|
|Continuing decline in area, extent and/or quality of habitat:||Yes|
|Major Threat(s):||The species' habitat is threatened by forest clearance for timber, followed by agriculture, especially at Nlonako, Bamboutos and Lebialem sites where there is active and ongoing deforestation.|
|Conservation Actions:||The future for Begonia adpressa seems bleak outside of the Rumpi Hills and Bakossi Mts. However, the species has been recorded in a single protected area, Mwanenguba National Park.|
