Description

Sand Forest, St Lucia Park Newtonia hildebrandtii00.jpg
Sand Forest, St Lucia Park

Newtonia hildebrandtii is a medium-sized tree growing to a height of about 25 m (80 ft). The trunk is usually rough, and the small branchlets and twigs are puberulous (densely covered with very short soft hairs) when young. The leaves are bi-pinnate and up to 8 cm (3 in) long, each leaf having four to seven pairs of pinnae, and each pinna having six to nineteen pairs of leaflets. There is usually a gland between each pair of pinnae. The leaflets are linear or oblong and up to 11 by 3 mm (0.43 by 0.12 in) long, with the underside often having raised lateral nerves. The inflorescence is a spike up to 8 cm (3 in) long composed of whitish or creamy flowers, which are followed by flattened pods up to 30 cm (12 in) long. [2] [3]

Distribution and habitat

This tree is found in eastern Africa, its range extending from Kenya and Tanzania, through Malawi, Zimbabwe and Zambia, to Mozambique, Eswatini and KwaZulu-Natal in South Africa. [3] Generally a tree of riverside forests, it also grows in sandy areas with a high water table, at altitudes of up to about 1,100 m (3,600 ft); [2] these include the Southern African Sand Forest. [4]

Uses

The timber of Newtonia hildebrandtii is used for building construction and for making poles and implements, and for carving. The wood burns well and makes good-quality charcoal. [2] Products from the tree are also used in traditional medicine; an extract of the roots is used against worms, and an extract from the bark has been shown to have antimicrobial activity against a range of pathogens.

<span class="mw-page-title-main">Forests of KwaZulu-Natal</span> Forest vegetation type in South Africa

Areas of forest which grow in KwaZulu-Natal, South Africa mostly on south facing slopes in higher rainfall areas, and along the humid coastal areas. Different types of forest can be identified by their species composition which depends mostly on the altitude, latitude and substrate in which they grow. South facing slopes are favourable for the development of forest as they are more shaded, and therefore cooler and retain more moisture than the northern slopes. The extra moisture on the south slopes is not only favoured by forest trees, but also helps to prevent or subdue wildfires. Fires can also be blocked by cliff faces and rocks or boulders on these slopes, and by streams or rivers at the base of the slopes. The coastal regions are conducive to forest formation, because of high rainfall and humidity which are favoured by forest trees and also help to prevent or subdue fires. The rivers of the coastal areas are also broader than further inland, which may often prevent fires from spreading long distances, and fires generally burn uphill and therefore more often away from areas at low altitude.
