Known from only eight submontane forest sites, this dramatic dioecious tree, one of only two Caricaceae on the African continent, is unmistakable even when sterile due to the broad, soft, spiny trunks which yield white exudate, and the digitately lobed leaves. It appears to be a pioneer, but is always very local, and usually gregarious.

It may now be extinct on Mt Cameroon and at Barombi, Kumba since no records have been found for either of these sites in nearly 100 years. Is threatened by forest clearance for ariculture and wood.

Conservation Actions [top]

Conservation Actions: The demography of this taxon is not documented and requires study. Nyasoso at Mt Kupe would be a good base for such research, and as a centre for conservation of the species since a sizeable population exists on the main trail to the summit at 1,100 m. Good populations also exist at Nkom-Wum and in the Bakossi Mts, near Kodmin. Extensive traditions attached to these trees are likely to help protect them in Bakossi.
