''Vachellia erioloba'' (camel thorn, giraffe thorn, (アフリカーンス語:Kameeldoring), (ツワナ語:Mogôtlhô), (ソト語:Mogohlo))〔(【引用サイトリンク】title=Protected Trees )〕 is a southern African legume.〔 The type specimen of ''Acacia giraffae'', proved on closer examination to be a hybrid of ''V. haematoxylon'' and the species which would later become known as ''V. erioloba''. The name ''V. erioloba'' was therefore proposed for the vast numbers of camel thorn which are not hybrids.〕 Its preferred habitat is the deep dry sandy soils of the Northern Provinces, western Free State, northern Cape Provinces, Botswana, and the western areas of Zimbabwe and Namibia. It is also native to Angola, south-west Mozambique, Zambia, KwaZulu-Natal, and Swaziland.〔 The tree was first described by Ernst Heinrich Friedrich Meyer and Johann Franz Drège in 1836. The tree can grow up to 17 metres high and is commonly found in Namibia. Its name refers to the fact that giraffe (''kameelperd'' in Afrikaans) and camels commonly graze on the harder-to-reach succulent leaves normally out of reach of smaller animals. Giraffe in particular are partial to all vachellias and manifest a specially-adapted tongue and lips that can cope with the vicious thorns. It also grows ear-shaped pods, which are favoured by a large number of herbivores including cattle. The wood is dark reddish-brown in colour and extremely dense and strong. It is slow-growing, very hardy to drought and fairly frost-resistant. The wood is a good fuel for fires, which leads to widespread clearing of dead trees and the felling of healthy trees. According to superstition, lightning will strike at ''V. erioloba'' more often than other trees.〔 The camel thorn's seeds can be roasted and used as a substitute for coffee beans. The camel thorn is a protected tree in South Africa.〔 == Gallery == Image:Acacia erioloba00.jpg|The pods of the Camel thorn, while they remain on a tree (near Potgietersrust in Transvaal, South Africa) Image:Camel thorn tree seeds.jpg|''Vachellia erioloba'' seeds, lying upon the ground, scattered among their pods, Sossusvlei, Namib Desert, Namibia Image:Acacia erioloba01.jpg|''Mokala'' Bark on a tree near Potgietersrust in Transvaal, South Africa Image:Acacia erioloba02.jpg|The sharp thorns of the ''Mokala'' resemble barbed wire (growing near Potgietersrust in Transvaal, South Africa) File:Thorn Tree Sossusvlei Namib Desert Namibia Luca Galuzzi 2004.JPG|''Vachellia erioloba'' tree in the Namib Desert File:Vachellia erioloba - Camel thorn.JPG|Vachellia erioloba, Kalahari desert 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Vachellia erioloba」の詳細全文を読む スポンサード リンク
