Description Trees or shrubs, the younger branches usually somewhat flattened and rotating to about 450 between the nodes. Leaves opposite, usually imparipinnate, often with the rachis winged between the opposite leaflets, rarely simple; stipules interpetiolar, caducous. Inflorescence frequently appearing terminal but axillary and usually opposite in the upper leaf-axils, a racemiform or spiciform thyrse with the pedicels clustered and nearly sessile upon the short side branches. Flowers numerous, small, perfect or polygamo-dioecious; sepals 4-5; petals 4-5, white or somewhat pinkish; stamens 8-10; ovary superior, 2- or rarely 3-celled, each carpel with a gradually produced, persistent style with simple stigma; ovules numerous, in 2 rows upon the axile placentae; disc fleshy, hypogynous, surrounding the ovary but free from the stamens. Fruit a small, thin, septicidally 2- or rarely 3-valved capsule; seeds small, usually pilose.
Habit Trees shrubs
Note Weinmannia is a genus of upward of 100 species of the tropics and subtropics of both hemispheres. The species are notoriously variable, and much confusion has resulted from the failure of certain students to appreciate this fact.
