Scientific Name: Begonia bonus-henricus
Species Authority: J.J.de Wilde

Assessment Information [top]

Red List Category & Criteria: Vulnerable A3c ver 3.1
Year Published: 2004
Date Assessed: 2004-04-30
Assessor(s): Cheek, M.
Reviewer(s): Hilton-Taylor, C. & Pollock, C.M. (Red List Programme Office)
Justification:
First described in 1980, this species was known from just five collections at four sites: ca. 15 km S.E. of Ebolowa, Rumpi Hills and, in Bakossi, Ngomboku and Ngussi. This geographical range is very similar to that of Newtonia duncan-thomasii, although the Begonia also occurs on Mt Kupe and has a slightly lower altitudinal range. Since then a further fifteen collections from Bakossi have been added. However, future clearance of forest for timber and agriculture at lower altitudes (below 1,000 m) is inevitable.

Habitat and Ecology [top]

Habitat and Ecology: This species is unique in sect. Squamibegonia Warb. (characterised by peltate scales, indehiscent globose berries, inflorescences enclosed in sheathing bracts) in having long (c. 1 m) slender (1.5 mm diam.) pendulous or rooting stems. It is a hemipiphytes and found in forest; 660–1,300 m alt.
Systems: Terrestrial

Threats [top]

Major Threat(s): Clearance of forest for timber and agriculture at lower altitudes (below 1,000 m) seems unfortunately inevitable in the Bakossi area.

Conservation Actions [top]

Conservation Actions: Assuming that proposed conservation plans in the Bakossi area are enacted, this locally common species seems fairly secure there above the 1,000 m contour and no other conservation action seems necessary.
