Meiocarpidium lepidotum is a species of plant in the family Annonaceae. It is native to Cameroon, The Central African Republic, The Republic of the Congo, and Gabon.[2] Daniel Oliver, the English botanist who first formally described the species using the basionym Unona lepidota, named it after rust-colored, shiny scales (Latinized form of Greek λεπίς, lepis)[3] on its branchlets, the underside of its leaves and its buds.[4]

Description[edit]

It is a tree reaching 25 feet in height. Its leathery leaves are 5-7 by 1.5-2 inches, and smooth on their upper surface. Its solitary flowers occur in extra-axillary positions and are bisexual. Its 3 sepals are oval to triangular in shape with edges that touch one another. It has 6 cream-colored petals arranged in two rows of three. The petals are roughly equal in size an have been observed adhering to one another at their apices to form a chamber around the reproductive structures. Its flowers have numerous stamen. Its flowers have 3-5 carpels. Its ovules are arranged in to rows positioned ventrally in ovaries. Its fruit have numerous seeds in a single row. The brown seeds are oval, rounded on one side and angled on the other.[4][5][6]

Reproductive biology[edit]

The pollen of M. lepidotum is shed as permanent tetrads.[7]

Uses[edit]

Bioactive molecules extracted from its bark have been reported to have analgesic, anti-inflammatory and antidepressant activities in tests with mice.[8]
