Belongs within: Malvaceae.

Sida is a widespread genus of herbs and shrubs found in warmer regions of the world. They produce yellow or orange, bisexual flowers that develop into schizocarp fruits with hard, often indehiscent mericarps (Harden 1990). Arrowleaf sida S. rhombifolia has historically been used as a source of fibre for cordage.

Characters (from Harden 1990): Herbs or shrubs with stellate hairs. Leaves shallowly lobed or more often unlobed, margins entire to toothed; petioles usually short. Flowers axillary, solitary or in terminal heads or spikes; peduncles often jointed. Epicalyx absent. Calyx 5-lobed, often 10-ribbed at base in fruit. Petals yellow to orange. Staminal tube slender. Ovary 5–10-locular, each loculus 1-ovulate; styles as many as loculi; stigmas terminal, capitate. Fruit a schizocarp; mericarps indehiscent or 2-valved.
