The rounded margins of the five petal lobes of Chaenostoma revolutum flowers are clear to see in this photo taken near Oudtshoorn. The flower tube varies in length from 5 mm to 13 mm; the corolla diameter varies between 10 mm and 15 mm. The mauve flowers have yellow throats from which two of the four stamens protrude, although the yellow anthers of the two shorter stamens are also visible in the corolla mouth. The white stigma protrudes as well. The flowers grow in racemes from leaf axils. They appear almost throughout the year after rain.
The narrow leaves, pale green and covered in gland-tipped hairs, are variable in length. Their rolled under margins are visible. Leaves may reach 2,5 cm in length. Similar hairiness as on the leaves is present upon the visible stem internodes (Manning, 2007; Vlok and Schutte-Vlok, 2010).
