説明（英語）: Genus of 4 species of low-growing, usually rosette-forming perennials from open, sandy areas in South Africa; some species have become naturalized in Portugal, Spain, and Australia. The leaves, often white-woolly, are pinnatifid with prominent lobes, toothed, or sometimes entire. The yellow, daisy-like flowerheads, with purplish black disc-florets in some species, are often tinged with bronze or purple, especially on the undersides; they are mostly solitary, but sometimes borne in twos or threes, on long, slender stems. Use for covering banks or for edging; usually treated as annuals in frost-prone areas.
