Combretum apiculatum | |
Combretum apiculatum is a species of tree in the family Combretaceae known by the common name red bushwillow. It is native to the mesic to semi-arid savanna regions of Africa, southwards of the equator.
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]
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]
It occurs in South Africa, Eswatini, 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 afra), sicklebush (Dichrostachys cinerea), large sourplum (Ximenia afra), livelong (Lannea discolor), white seringa (Kirkia acuminata), and marula (Sclerocarya afra). [5]
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]
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]
The Kalahari Desert is a large semi-arid sandy savanna in Southern Africa extending for 900,000 square kilometres (350,000 sq mi), covering much of Botswana, as well as parts of Namibia and South Africa.
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 not abundant—frost, fire and grazing animals allow grass to grow, but prevent the build-up of dense foliage.
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 hardtwood 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.
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.
Gonimbrasia belina is a species of emperor moth which is native to the warmer parts of southern Africa. Its large edible caterpillar, known as the mophane worm, madora, amacimbi “pigeon moth”, masontja or Seboko sa Mongana, feeds primarily but not exclusively on mopane tree leaves. Mophane worms are an important source of protein for many in the region. The species was first scientifically described by John O. Westwood in 1849.
The wildlife of Botswana refers to the flora and fauna of this country. 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 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.
The white-bellied sunbird, also known as the white-breasted sunbird, is a species of bird in the family Nectariniidae. It is found in Angola, Botswana, Democratic Republic of the Congo, Eswatini, Malawi, Mozambique, Namibia, South Africa, Tanzania, Zambia, and Zimbabwe.
The Kalahari Acacia-Baikiaea woodlands are an ecoregion located in Botswana, northern Namibia, South Africa and Zimbabwe.
Vachellia reficiens, commonly known as red-bark acacia, red thorn, false umbrella tree, or false umbrella thorn, is a deciduous tree or shrub of the pea family (Fabaceae) native to southern Africa, often growing in an upside-down cone shape and with a relatively flat crown.
Combretum erythrophyllum, commonly known as the river bushwillow, is a medium-sized, spreading tree found in bush near or along river banks in southern Africa. It is planted as a shade and ornamental tree in South Africa and the United States, and is propagated by seed.
Terminalia sericea is a species of deciduous tree of the genus Terminalia that is native to southern Africa. Its common names include clusterleaf, silver cluster-leaf or silver terminalia in English, vaalboom in Afrikaans and mususu in Venda.
Senegalia ataxacantha, commonly known as the flame thorn, is an African tree species with conspicuous red pods and numerous hooked prickles.
The West Sudanian savanna is a tropical savanna ecoregion that extends across West Africa.
Combretum hereroense, commonly known as the russet bushwillow and the mouse-eared combretum, is a deciduous shrub or small tree that is found from eastern Africa to northern South Africa. Over its extensive range it is variable with respect to leaf shape, fruit size and indumentum.
Boscia foetida, commonly known as the stink shepherd's tree and the smelly shepherd's bush, is an evergreen shrub or tree that is native to the warmer and drier parts southern Africa. It is found in semi-desert and arid bushveld, and in the west it occurs commonly in areas which are otherwise sparsely wooded. It is known for the particularly unpleasant smell of its flowers which appear during early spring, to which its specific name foetida alludes. Its freshly cut wood likewise has an unpleasant smell, and has traditional medicinal and magical uses, for instance as a protection against lightning. In central Botswana the village of Mopipi is named after this species.
Allophylus natalensis, commonly known as the dune false crowberry or dune false currant, is a species of plant in the genus Allophylus native to south-eastern Africa.
Combretum zeyheri, the large-fruited bushwillow or Zeyher's bushwillow, is a species of flowering plant in the family Combretaceae, usually found growing on acidic or sandy soils in tropical African savannas. A small to medium-sized tree, its roots are used as a source of material for making baskets and as a traditional medicine for haemorrhoids.
