Osmitopsis asteriscoides, the swamp daisy or belskruie in Afrikaans, is a slender camphor-scented shrub of the far south-western part of the Western Cape. It grows in moist areas such as seeps and marshes where it may reach 2 m in height.
The flowers appear in loose clusters. The ray flowers are oblong with rounded tips. The central disc is yellow. There is no pappus on the fruit. The daisy flowers may appear at almost any time of the year, although autumn and early winter may see no flowers.
The leaves are ascending, alternate, sessile and sometimes felted with white velvety hairs. Leaf shape is lanceolate, tapering to the tip. The leaves are concentrated near stem tips, with older stems on mature plants long and bare.
The plant has a history of traditional medicinal uses in some local cultures (Manning, 2007; Bond and Goldblatt, 1984).
