The species is deciduous, hardy and normally grows to about 5m tall. Branches are quite rigid, hence its specific name. Leaves are in tufts, leathery and rough with adpressed minute barbs along the margins. Almost invariably there are small pockets of hairs or [[acarodomatia]], providing a refuge for mites in the axils of veins on the underside of the leaves. Bark is smooth and uniformly ash-grey, becoming rough on older stems. Fragrant lilac-coloured to white flowers are produced in early spring and are followed by small 8mm diameter fruits bearing a persistent style, green at first, turning orange, red and finally black. <ref>[http://www.aluka.org/action/showCompilationPage?doi=10.5555/AL.AP.COMPILATION.PLANT-NAME-SPECIES.EHRETIA.RIGIDA&cookieSet=1 Aluka]</ref> |

Ehretia rigida, commonly known as Deurmekaarbos (Afrikaans = "confused/tangled bush"), is a small, multi-stemmed tree with a tangled growth habit belonging to the Boraginaceae or borage family. It occurs over a wide range of habitat throughout the eastern part of South Africa, and in Namibia, Botswana, Zimbabwe and Mozambique.
The species is deciduous, hardy and normally grows to about 5m tall. Branches are quite rigid, hence its specific name. Leaves are in tufts, leathery and rough with adpressed minute barbs along the margins. Almost invariably there are small pockets of hairs or acarodomatia, providing a refuge for mites in the axils of veins on the underside of the leaves. Bark is smooth and uniformly ash-grey, becoming rough on older stems. Fragrant lilac-coloured to white flowers are produced in early spring and are followed by small 8mm diameter fruits bearing a persistent style, green at first, turning orange, red and finally black. [1] Ripe fruits of this plant are edible but not tasty.
The genus honours the botanist Georg Dionysius Ehret, a celebrated botanist and botanical illustrator of the 18th century. [2]
