Cameroon . East Region ; Bitya, near Dja river , Bates G.L. 1792 , Sep 1922 : holotype : P[00363370] . Description. Differs from the type variety by its densely brown tomentose and shortly hirsute branches and petioles, pubescent lower side of leaf blades and tomentose petals. Distribution. A west and central African species, from Sierra Leone to Benin and from Cameroon to the Democratic Republic of the Congo; in Cameroon known from Central, East, South and South-West regions. Habitat. A fairly common species in Cameroon, in secondary rain forests a long fringes of forests, in swampy regions too. Altitude 100-800 m a.s.l. Local and common names known in Cameroon. None recorded. IUCN conservation status. Not evaluated. Uses in Cameroon. None recorded. Notes. Differences between var. Artabotrys insignis insignis and var. Artabotrys insignis batesii are quite small, and are mainly related to the pubescence of the branches, lower side of the leaves and petals ( Le Thomas 1965a ). There is one more recognized variety within Artabotrys insignis : var. Artabotrys insignis concolor (Pellegr.) Le Thomas which differs by having shiny leaves on both sides and longer sepals. We have not seen this variety in Cameroon, but it is present in Gabon ( Le Thomas 1965a , 1969b ). Figure 14.
