Description

This is a semi-deciduous tree growing up to 10 meters tall, or sometimes a shrub remaining shorter. It has rough gray-black bark with fissures, and the smaller branches may be woolly in texture. The oppositely arranged leaves are up to 11 [1] to 13 [2] centimeters long. They are hairless or hairy. The tip of the leaf tapers abruptly to a twisted point. [1] [2] The foliage turns reddish or golden in the fall. [3] The spike inflorescences emerge between the leaves and are up to 7 centimeters long. They bear yellow or greenish flowers with tiny sepals and petals, and with style and stamens about half a centimeter long. [2] The flowers have a strong scent. [3] The reddish, winged fruit is 2 or 3 centimeters long. [1] [2]

Subspecies

There are two subspecies, the southern ssp. apiculatum, and ssp. leutweinii, which occurs from Namibia to Malawi and northwards, which is differentiated by its more hirsute leaves. [3]

Range and habitat

It occurs in South Africa, Swaziland, Botswana, Mozambique, Namibia, Zimbabwe, [1] southern Angola, Zambia, Malawi, southeastern DRC, Tanzania and southern Kenya. [4]

This tree occurs in various ecosystems in southern Africa. It is the dominant tree on the savanna in many areas, [5] [6] including regions characterized as lowveld and mopane savanna. It grows alongside other woody vegetation such as common hook thorn (Acacia caffra), sicklebush (Dichrostachys cinerea), large sourplum (Ximenia caffra), livelong (Lannea discolor), white seringa (Kirkia acuminata), and marula (Sclerocarya caffra). [5]

Utilization by game and livestock

Many animals use the tree, especially for food. Kudu, bushbuck, elands, giraffes, and elephants browse the leaves. [3] Eland are so attracted to the tree that they can do damage to it with their feeding. [7] The brown-headed parrot eats the seeds. [1]

Cattle also eat the leaves. The fruits are hazardous to livestock, however, because they are toxic. [3] The foliage can be fed to goats as a supplemental fodder. [8]

This tree has dense (1.15), [9] fine-grained, strong, dark brown to black heartwood, sometimes used as firewood or for making charcoal. [1] It is hard, and termite-resistant. [3] The tree responds well to coppicing, growing back with plentiful foliage. [10] The bark has been used in leather tanning. [3] Medicinal uses for the species include the treatment of conjunctivitis and stomach ailments. [1] [3] It contains a number of antioxidant compounds, such as cardamonin, pinocembrin, quercetin, and kaempferol. [11] It is an appropriate garden tree, as it is tolerant of frost and drought and provides shade. [3]

Vernacular names

Common names for the tree in other languages include rooiboswilg (Afrikaans), umbondwe (Zulu), imbondvo (Swazi), mohwidiri (Tswana), mohwelere (Sepedi), muvuvha (Tshivenḓa), ndhuva (Tsonga), [3] rukweza (Shona), and omumbuti (Herero). [12]

Tropical and subtropical grasslands, savannas, and shrublands Terrestrial habitat type defined by the World Wide Fund for Nature

Tropical and subtropical grasslands, savannas, and shrublands is a terrestrial biome defined by the World Wide Fund for Nature. The biome is dominated by grass and/or shrubs located in semi-arid to semi-humid climate regions of subtropical and tropical latitudes.

Veld

Veld, also spelled veldt, is a type of wide open rural landscape in Southern Africa. Particularly, it is a flat area covered in grass or low scrub, especially in the countries of South Africa, Lesotho, Eswatini, Zimbabwe and Botswana. A certain sub-tropical woodland ecoregion of Southern Africa has been officially defined as the Bushveld by the World Wide Fund for Nature. Trees are found only in a few places—frost, fire and grazing animals allow grass to grow but prevent the growth of trees.

Common eland Second largest antelope in the world

The common eland, also known as the southern eland or eland antelope, is a savannah and plains antelope found in East and Southern Africa. It is a species of the family Bovidae and genus Taurotragus. An adult male is around 1.6 metres (5') tall at the shoulder and can weigh up to 942 kg (2,077 lb) with an average of 500–600 kg (1,100–1,300 lb), 340–445 kg (750–981 lb) for females). It is the second largest antelope in the world, being slightly smaller on average than the giant eland. It was scientifically described by Peter Simon Pallas in 1766.

<i>Combretum imberbe</i> Species of tree

Combretum imberbe is a characteristic and often impressive bushwillow species of the southern Afrotropics. The medium to large tree has a sparse, semi-deciduous canopy of grey-green leaves. The twigs and leaves are hairless as the name imberbe suggests. Its heartwood is dark brown, close-grained, and very hard and heavy, as suggested by its vernacular name. The durable heartwood is much sought after in the woodcarving industry. The Hereros and Ovambos of Namibia attach special cultural and religious significance to the tree, as to them it is the great ancestor of all animals and people, which must be passed with respect.

<i>Combretum</i> Genus of plants in Combretaecae family

Combretum, the bushwillows or combretums, make up the type genus of the family Combretaceae. The genus comprises about 272 species of trees and shrubs, most of which are native to tropical and southern Africa, about 5 to Madagascar, but there are others that are native to tropical Asia, New Guinea and the Bismarck Archipelago, Australia, and tropical America. Though somewhat reminiscent of willows (Salix) in their habitus, they are not particularly close relatives of these.

Wildlife of Botswana The flora and fauna of Botswana

The wildlife of Botswana refers to the flora and fauna of Botswana. Botswana is around 90% covered in savanna, varying from shrub savanna in the southwest in the dry areas to tree savanna consisting of trees and grass in the wetter areas. Even under the hot conditions of the Kalahari Desert, many different species survive; in fact the country has more than 2500 species of plants and 650 species of trees. Vegetation and its wild fruits are also extremely important to rural populations living in the desert and are the principal source of food, fuel and medicine for many inhabitants.
