It was previously included within the related genus Lampranthus, but was split off as a separate genus, due to differences in its fruit and flower.
Description
The most superficially recognisable feature of the genus is the shape of the leaves, which are grey-green and waxy. They are triangular in cross-section (3 angled) and can be sickle, club or mouth shaped. The name "Oscularia" actually means "group of tiny mouths" in Latin, and refers to the appearance of the toothed leaves in some species.[citation needed] The stems are often red, and the leaves can become red too during times of drought.
Abundant, almond-scented, daisy-like white or pink flowers appear throughout the summer.[2][3]
Distribution
The species are restricted to the Western Cape Province, South Africa, where they occur only in winter rainfall areas. Their habitat is typically rocky areas of sandstone.[4]
The species Oscularia deltoides is cultivated as an ornamental garden plant.
