| Description: | Ursinia nana DC.: Ursinia nana is a member of the sunflower family (Asteraceae) which grows to a height of about 200 mm and with a spread of 150 mm. The growth rate is fast, with a longevity of 5 months. Stems are wiry. Roots are non-invasive. The leaves are bunched, feathery, deeply laciniate (irregularly and finely cut), finely divided into narrow segments, 15–50 mm long, hairless. It bears a single yellow, radiate (daisy-like) flowerhead, 10–35 mm in diameter, on a short peduncle, at the tip of a long, leafless stem, about 120 mm long, the tip drooping when still in bud. The palaea (bracts at the base of the disc florets) are boat-shaped. The involucral bracts, around the base of the flowerhead, are rounded, with wide papery tips, often with dark crescent marks at the apex. The fruit has a biseriate (in 2 rows) pappus, with 5, broad, white, petal-like scales and 5 bristles at the tip. The fruits ripen over a period of time. The flowering period takes about 2 months, from spring to early summer (Aug. –Oct.). (from http://pza.sanbi.org/ursinia-nana) Ursinia nana DC.: Low-growing annual herb, up to 120 mm high. Leaves twice-divided, slightly fleshy, up to 35 mm long. Flower heads solitary on leafless stalks, up to 25 mm in diameter; flower bracts broadly triangular with dark edge preceding broad, membranous, transparent margin, blunt to rounded at the tip; ray floret limbs yellow to orange; disc florets yellow to brownish. Flowering July to October, peaking August to October. Fruit with very conspicuous, papery white crown at tip when mature, giving the impression that plant has white flowers.
