Botanical name: Sida schimperiana Family: Malvaceae (Mallow family)
Schimper's Sida is a perennial herb, with a very thick woody rootstock. It is named for Georg Heinrich Wilhelm Schimper (1804-1878), a German botanist and naturalist. From the top of the rootstock, arise a large number of trailing or erect repeatedly forked branches, 6-12 inches long. Leaf-stalk is shorter than the leaves, which are small, 1.2 cm long, oblong, retuse, wedge-shaped at the base, sparsely covered with star-shaped hairs; stipules small, ligulate. Flowers are solitary, in leaf-axils, on very short jointed stalks, which are sometimes crowded towards the end of the branches. Calyx is broad-cup-shaped, 5-cleft; sepals triangular. Flowers are yellow; petals about 5 x 2 mm, hairless. Staminal column about 1.5 mm long, star-shaped-hairy. Ovary about 1 mm high, ovoid, hairless. Fruit is globular, of 5 hairless, 1-seeded, slightly beaked carpels (beak bent inwards) splitting along the inner edge. Schimper's Sida is found in Peninsular India and Africa.
