Description

Disphyma papillatum is a succulent, prostrate herb with pimply, two-angled, trailing stems rooting at the nodes, up to 50 cm (20 in) long, the internodes mostly 20–30 mm (0.79–1.18 in) long. The leaves are arranged in pairs, stem-clasping with their bases joined, each leaf triangular in cross-section, mostly 10–15 mm (0.39–0.59 in) long and 5–6 mm (0.20–0.24 in) wide, tapering towards the tip. The flowers are superficially daisy-like, 20–40 mm (0.79–1.57 in) in diameter on a pimply pedicel 20–30 mm (0.79–1.18 in) long with five sepals at the base. The petals are white, pink, dark blue or purple in three to five rows, each petal 10–30 mm (0.39–1.18 in) long and 1.5–2 mm (0.059–0.079 in) wide. There are many stamens with yellow anthers and five or six styles. Flowering occurs from November to January and the fruit is a capsule 5–12 mm (0.20–0.47 in) in diameter before opening. It is similar to Disphyma crassifolium but is distinguished from that species by its pimply, rather than smooth, and flattened, two-angled rather than cylindrical stems.[2][3][4]
