About Pteronia glauca Thunb.
Pteronia glauca Thunb. is a shrub that grows to roughly 60 cm in height. It typically has outer branches that droop downwards, especially when growing in very rocky ground, and its branches can root where they touch the ground. This plant forms a low, dense bush, and has small, 5 by 3 mm, light grey, woolly, fragrant leaves. Small yellow flowerheads 5 mm wide appear in Spring at the tips of the branches. The flowerheads have non-sticky yellow bracts. This species is distributed across the arid interior Karoo regions of South Africa, ranging from Namaqualand, through the Great Karoo and Little Karoo, into Eastern Cape Province. Its natural habitat is renosterveld and succulent karoo vegetation, where it often grows in loamy soils or arid flood plains with underlying calcrete.
