Les Rinorea comme indicateurs des grands types forestiers du Cameroun

The Biodiversity of African Plants

Résumé

Les Rinorea (Violaceae) sont des bio-indicateurs très sensibles des types forestiers. En sous-bois, les aires de distribution épousent les contours des faciès forestiers, reflets des zones biogéographiques. Au Cameroun, on distingue en particulier les Rinorea de la plaine littorale et les Rinorea du plateau. A l’intérieur de chaque division, les Rinorea s’associent en unités dont les aires coïncident parfaitement aux zones de refuge reconnue par de nombreux auteurs dont Amiet (1987), Maley (1987) et récemment Sosef (1994).

Abstract

Rinorea species (Violaceae) present sensible bioindicators for forest typification. In understorey forest, their distribution often coincides with the forest facies contour. In Cameroon in particular, there are two groups of Rinorea species: species of the coastal plain and species of the plateau. In each of these two groups, there are species-associations from which the distributions coincide exactly with the refuge zones well known in Cameroon, as outlined by many authors e.g. Amiet (1987), Maley (1987) and recently Sosef (1994).
