Osteospermum calendulaceum is a spreading, aromatic, annual herb to 30cm, with narrow lanceolate leaves and yellow flowers. The fruits are unwinged. Found in disturbed shrubland from Kalgoorlie to the Nullarbor. O. clandestinum (stinking Roger) is a slightly sticky, erect annual to 50cm. The flowering heads are grouped into terminal inflorescences, erect in flower but drooping in fruit. The heads are distinctively coloured, as the ray florets are banded yellow and brown, while the disc florets are dark red. After flowering, the bracts enlarge slightly to enclose the fruits. Widespread on roadsides and in open bushland throughout the south-west. Both flower in spring and are native to South Africa.
