HABITAT AND DISTRIBUTION. — Rain forest in SW Gabon. Only known from the type locality. Alt. below 300 m.

NOTES. — The type specimen of T. nyangensis consists of a mixture of leaves and female as well as male flowers. The collector, LE TESTU, was not certain about the flowers, whether they were: “polygames? dioiques? Je crois plutôt polygames”. More collections with better field observations are needed to see whether T. nyangensis is dioecious like all other members of the genus or not (but see also Notes under T. rubicunda ).
