Two new tree species, Didelotia korupensis and Tessmannia korupensis (Leguminosae, Caesalpinioideae), are described and illustrated. Didelotia korupensis is the 12th species in the genus. It is an understory tree to 15 m tall with an often leaning stem to 30(–53) cm diam. Didelotia korupensis is only known from an area of c. 4 km2 in and near the permanent plots along the P transect in the southern part of Korup National Park in Cameroon, where 51 trees have been recorded so far. Didelotia korupensis is assessed according to IUCN criteria as Endangered. Tessmannia korupensis is the 13th species in the genus. It is a canopy tree to 39 m tall with a stem to 105 cm diam. Tessmannia korupensis is known from seven groups of trees of 9 to 43 trees each, in and near the permanent plots along the P transect in the southern part of Korup National Park and from a single collection made in the lowland rain forest near Mt Cameroon. Tessmannia korupensis is assessed according to IUCN criteria as Endangered.
