Habitat

Species occurrence increases with rainfall to reach a very wide optimum range between 1500-3500 mm/yr (logistic regression analysis, Chi2 test). Most often in lowlands (logistic regression analysis, Chi2 test), although, in Ghana, it is very frequently recorded in upland forests (Hall & Swaine 1981). It can be found in a wide variety of evergreen and semi-deciduous forests. Usually under shade, and very often along creeks or rivers. Soils can be sandy, loamy, clayish, or lateritic (herbarium). In Ghana, plot records are very significantly associated

with acidic, base-poor soils (Hall & Swaine 1981). In Côte d'lvoire, it is typical for coastal wet evergreen forests (Kasparek 2000).
