Spinyhead Sida

Sida acuta, the common wireweed, is a species of flowering plant in the mallow family, Malvaceae. It is believed to have originated in Central America, but today has a pantropical distribution and is considered a weed in some areas. In India, the indigenous people of Garo Hills in Meghalaya use this plant to make brooms.

In northern Australia, Sida acuta is considered an invasive species, and the beetle Calligrapha pantherina has been introduced as a biological control agent in an attempt to control the plant.
