Newtonia paucijuga

Newtonia hildebrandtii is a fairly large tree growing to a height of about 35 m (110 ft). The trunk is usually smooth and some shade of grey or greyish brown, and the small twigs are densely covered with reddish-brown hairs when young. The leaves are alternate and bi-pinnate, up to 4 cm (2 in) long, each leaf having one or two pairs of pinnae, and each pinna having two to three pairs of leaflets. There is a short gland between each pair of pinnae and further short glands between each pair of leaflets. The leaflets are linear or oblong and up to 7 by 4 cm (2.8 by 1.6 in), with stalked and wedge-shaped bases and rounded apexes. The inflorescence is a dense hairy spike up to 10 cm (4 in) long at the tip of the twig or in a leaf axil. The white flowers are bisexual and have parts in fives. They are followed by reddish-brown, flattened pods up to 30 by 3 cm (12 by 1 in). The seeds are flat and oblong, with a papery wing.[2]

Newtonia paucijuga is native to East Africa, where its range extends from southeastern Kenya to southern Tanzania. It is found in forests at elevations of up to 500 m (1,640 ft); this can be moist evergreen forest or drier evergreen forest, as well as riverine forest and secondary forest. These types of habitat are under threat from human development.[2]

This tree is fairly common in suitable habitat in East Africa, for example in the Shimba Hills in Kenya, but it has a limited range, being only found in fragments of coastal and gallery forest, and the International Union for Conservation of Nature has assessed its conservation status as "vulnerable".[1]
