Description :
The different species of rain-forest plants developing starchy tubers were studied around Makokou (N. E. Gabon) and in the Lobaye River district (S. W. Central African Republic). A detailed description of the tuberous parts is given, particularly in wild yams to help to elucidate the taxonomic status of a number of species. The different underground storage structures are considered as adaptive to the rain-forest environment. An estimate of the underground tuber biomass has been made. The benefits of energy storage in tubers and the reproductive strategies of the various plant species concerned are discussed in relation to the selective pressures exerted by animal consumers, not forgetting human traditional hunter-gatherers.
