Monteiro Sida is a genus of flowering plants in the mallow family, Malvaceae.

The leaf blades are usually unlobed with serrated edges, but may be divided into lobes.

Each has five hairy sepals and five petals in shades of yellow, orange, or white.

The fruit is a disc-shaped schizocarp up to 2 cm (3/4 inch) wide which is divided into five to 12 sections, each containing one seed.

[3] Sida has historically been a wastebasket taxon, including many plants that simply did not fit into other genera of the Malvaceae.
