Description

edit

It is a small deciduous tree, which can grow up to 7 m (23 ft) tall. It has black, fissured rough bark and also drooping branches. Between September and October, when the tree has no leaves it begins to bloom, with lilac blue flowers. Later it produces a seed capsule, the grey pods contain 3-8 smooth, bright yellow or brown seeds.[5]

The wood is very hard, heavy and yellow in colour. It can be used for axe-handles, wagon spokes and fencing poles. The tree is also grown in gardens due to the attractive flowers.[5]

Distribution

It is native to KwaZulu-Natal and Northern Provinces (of South Africa), Eswatini, Botswana, Malawi, Mozambique, Zambia and Zimbabwe.[1] It is found in low to medium elevations in woodland or wooded grasslands.[5]

Taxonomy

edit

The genus name of Bolusanthus is in honour of Harry Bolus, (1834 – 1911) who was a South African botanist, botanical artist, businessman and philanthropist,[6] and 'anthus' the Greek word for flower.

It was first published and described by (Bolus) Hermann Harms (a German botanist) in Repert. Spec. Nov. Regni Veg. 2: 15 in 1906.[1]
