Common Sida are annual or perennial herbs or shrubs growing 20 centimetres (7.9 in) to two metres (6 ft 7 in) tall. Most species have hairy herbage. The leaf blades are usually unlobed with serrated edges, but may be divided into lobes. They are borne on petioles and have stipules. Flowers are solitary or arranged in inflorescences of various forms. Each has five hairy sepals and five petals in shades of yellow, orange, or white. There are many stamens and a style divided into several branches. The fruit is a disc-shaped schizocarp up to two centimetres (0.79 in) wide which is divided into five to 12 sections, each containing a seed.
