Periglossum angustifolium

Periglossum angustifolium, commonly known as the round head and previously scientifically as Cordylogyne argillicola, is a perennial growing from a tuberous rootstock, reaching heights from 30 cm to 76 cm. The genus forms part of the Apocynaceae family. Two of the four species occur in South Africa, the others in southern Africa.

The species distribution is widespread in the east of South Africa, from the Eastern Cape through the Free State and KwaZulu-Natal to Mpumalanga, Gauteng and North West. The photo was taken in KwaZulu-Natal.

The habitat is usually unburnt grassland, savanna-like or swampy, up to elevations around 2000 m. The habitat population is deemed of least concern early in the twenty first century (Leistner, (Ed.), 2000; Pooley, 1998; iNaturalist; https://www.worldfloraonline.org; http://redlist.sanbi.org).
