Sida mysorensis Wight & Arn.

It is of rare occurrence in Pakistan.

Sida mysorensis is often confused with the closely related species S. javensis Cavanilles and S. cordata (N. L. Burman) Borssum Waalkes but can usually be distinguished by the presence of glandular hairs and the erect habit.

It is very close to the preceding species from which it may be distinguished by the presence of glandular hairs on branches, petioles and pedicels.

Herbs subshrublike, erect, to 1 m tall. Stem with minute stellate hairs, multicellular glandular hairs, and long simple hairs. Stipule filiform, ca. 5 mm; petiole 1-3 cm, pilose; leaf blade ovate-cordate, 3-6 × 2.5-4.5 cm, viscid-stellate on both surfaces with minute stellate hairs and multicellular glandular hairs, base cordate, margin crenate, apex acuminate. Flowers solitary or paired, axillary or subterminal, often on congested reduced axillary shoots. Pedicel slender, 2-6(-15) mm, articulate at or above middle. Calyx widely campanulate, 6-8 mm, sparsely pilose with long hairs, lobes 2.5-3 × ca. 2.5 mm, acute or acuminate. Corolla yellow, 1-1.2 cm in diam.; petals obtriangular, glabrous. Filament tube strigose. Schizocarp nearly globose, 3-4 mm in diam.; mericarps 5, ovoid-tetrahedral, ca. 2.5 mm, smooth, apex shortly hairy, not awned, shortly acute, enclosed in persistent calyx. Seeds ovoid, slightly 3-sided, ca. 2 mm, glabrous.

Distribution: Common in Tropical Asia.

Forest margins, slopes, grassy roadsides. Guangdong, Guangxi, Hainan, Taiwan, Yunnan [Cambodia, India, Indonesia, Laos, Philippines, Thailand, Vietnam].

Sida mysorensis, common name in India Mysore fanpetals, is a plant species native to South and Southeast Asia. It has been reported from the wild in Indonesia, Vietnam, Laos, Cambodia, Thailand, India, Pakistan and southern China, and is cultivated elsewhere. It grows in grassy slopes, on roadsides, and in forest boundaries.

Sida mysorensis is an erect herb up to 1 m (40 inches) tall. The stem and leaves are covered with stellate and glandular hairs. Leaves are ovate (egg-shaped) to cordate (heart-shaped), up to 6 cm (2.4 inches) long. Flowers are yellow, solitary in leaf axils or at the tips of branches.

Sida mysorensis is similar to S. javensis and S. cordata but distinguished by its erect habit and hairy shoots.

The species is named for the City of Mysore, India.
