Assessor(s): Bösenberg, J.D.
Reviewer(s): Donaldson, J.S. & Hilton-Taylor, C.
Justification:
The species is recorded as growing in large numbers in the eastern DRC (Goode 2001) and that seed set is occurring. It has also been recorded from across the border in Angola but there is no data available on population numbers. Available data suggests that populations are stable. If there was any evidence of decline, it would probably qualify for a Vulnerable listing under criterion B1ab(v).
