About Oedera uniflora (L.fil.) Anderb. & K.Bremer
Oedera uniflora is a small shrub with extremely sticky leaves that are arranged in four distinct ranks. Each leaf has a tip that curves slightly downward, and a distinct basal abscission line. Its yellow flowerheads are typically solitary, emerging at the tips of branches during spring and summer. This species can look similar to Oedera garnotii, but Oedera garnotii has leaves arranged in an imbricate pattern, with each leaf being straight and marked by a longitudinal groove. Oedera uniflora is endemic to the Western Cape Province of South Africa. Its range extends from the Robertson Karoo and Overberg regions south to Bredasdorp and the Agulhas plain, and east as far as Riversdale and Mossel Bay. A separate, outlying set of populations is also found much further west, near Saldanha. It most commonly grows in coastal limestone or sand, and also occurs on rocky shale hill slopes.
