Habitat. An uncommon species in Cameroon; in primary and secondary rain forests and along streams, generally on sandy soil. Altitude 0-400 m a.s.l. Local and common names known in Cameroon. None recorded. IUCN conservation status. Least Concern (LC) (Cosiaux et al. 2019z). Uses in Cameroon. None reported. Notes. <i>Monodora crispata</i> is characterized by its generally lianescent habit resembling a woody climber growing on rocks or larger trees, the petals with very crispy margins, entirely glabrous branches and leaves, and ellipsoid and conspicuously 6-7-ribbed fruits. Cheek and Cable (1998) mention from Mt Cameroon an <i>Isolona</i> sp. nov. (<i>Watts 687, Wheatley 501</i>), however these are now identified as <i>Monodora crispata</i>.
