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.

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.

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
).
