Red List Category & Criteria: Endangered B2ab(iii) ver 3.1
Year Published: 2015

This tree (to 80 cm diam.) is known from only three sites, N. Gabon (Le Testu 9376, K, type), Abong Mbang (Letouzey 3961, L) and a plot voucher specimen from the Mt Cameroon foothills at Mabeta-Moliwe, now known as Bimbia-Bonadikombe (Cheek in W 831, transect B, plot -1, June 1992, identified by G. Prance, K). This tree seems extremely rare though fairly widespread. A specimen record (Ewango) from Orientale Province, DRC identified by the collector as this species is to be treated with caution since it differs in several features from other material of the species. This species was assessed as Critically Endangered (CR) A1c+2c by Cheek in Cable and Cheek (1998). This is modified here since although the site at Mt Cameroon has probably been lost due to small-holder market-gardening according to reports of Corcoran and Alicha in recent years, there is no detailed information on threats at the other sites. Therefore the original assessment seems inappropriate and the species is now assessed as Endangered because it has a small minimum area of occupancy of 12 km² (it is unlikely to exceed 500 km²), is known from three locations and there is continuing decline in the extent and quality of the habitat due to the impacts of logging and agricultural expansion on the habitat.
Previously published Red List assessments:
2000 Critically Endangered (CR)

Geographic Range [top]

Range Description: Recorded from Cameroon (Southwest Region: Bimbia-Bondikombe at Mt Cameroon; South Region: Abong Mbang), and N Gabon. A collection from the Okapi Reserve in eastern Democratic Republic of the Congo (DRC) identified as this species is considered to be doubtful and hence is excluded from this assessment.
Countries occurrence:
Cameroon; Gabon
Estimated area of occupancy (AOO) - km2: 12

Population [top]

Population: Although widespread this tree seems to be extremely rare.
Current Population Trend: Decreasing
Additional data:
Population severely fragmented: No

Habitat and Ecology [top]

Habitat and Ecology: A large tree found growing in lowland evergreen forest; elevation limits are not known.
Systems: Terrestrial
Continuing decline in area, extent and/or quality of habitat: Yes

Threats [top]

Major Threat(s): Forest clearance for timber extraction and agricultural expansion are the main threats.

Conservation Actions [top]

Conservation Actions: Although habitat loss in recent years in the Bimbia area is not encouraging, a further effort should be made to retrace this plant at the plot in which it was found in Mabeta-Moliwe (TB-1) in 1992, and thence to acquire the information necessary to protect this species at that site and to introduce it to Limbe Botanic Garden for multiplication and reintroduction at secure sites.
