Illustration

Credit: M.Y. Saleem

Annual or perennial herbs, glabrous or ± pubescent with simple unicel¬lular upcurved hairs. Leaves usually alternate, exstipulate. Racemes terminal or lateral. Sepals 5, usually persistent. Petals 3, ± united below. Stamens usually 8, ± united into a staminal sheath and adnate to the petals. Ovary 2-locular, ovule one in each loculus. Capsule 2-seeded, loculicidal, compressed. Seeds ± pilose, strophiole usually 3-lobed.

A large and difficult genus of about 600 species, distributed throughout the world except New Zealand, Polynesia and arctic zone; represented in West Pakistan by 8-10 species, unevenly distributed throughout the country, greater concentration of species being found in the Punjab and Kashmir.
