Shrub or small tree 1.2-5 m high, 4 cm dbh. Leaves imparipinnate with 4-8 pairs of lateral leaflets; Stipules ± orbicular, up to 0.5 by 0.6 cm, apex broadly rounded or flattened. Inflorescence a pair of opposite dyads; Flowers unisexual? (only male ones seen); Fruit not seen.
Asia-Tropical, Gn. Brinchang present, Gn. Ulu Kali present, mountains in western Peninsular Malaysia present
Malesia: mountains in western Peninsular Malaysia (Gn. Ulu Kali and Gn. Brinchang).
2. Probably dioecious but so far only male flowers have been found. 3. Appears to be closely related to W. fraxinea, and resembles somewhat small-leafleted variants of that species which occur in some localities at high altitude. However, on Gn. Ulu Kali both taxa grow in close proximity and can be readily distinguished, as W. fraxinea has much larger, narrowly elliptic leaflets. 1 The leaves are clustered towards the end of the twigs and held ± erect to form an even, dense, ball-like, congested crown. Young branches and leaf rachises are purplish or brown and adult foliage is dark green above and leathery.
