Ayenia obtusata is a species of flowering plant in the mallow family, Malvaceae. It is a small, herbaceous perennial or subshrub native to the southeastern United States, primarily found in Florida, but also occurring in parts of Georgia, Alabama, Mississippi, Louisiana, and potentially Texas.
Description
Ayenia obtusata typically grows as a low-lying, often sprawling plant, reaching heights of generally 10 to 40 centimeters (4 to 16 inches). Its stems are slender and sometimes woody at the base. The leaves are alternate, simple, and characterized by their shape, which is often obovate to broadly elliptic with a rounded or blunted (obtuse) apex, giving the species its epithet "obtusata." They are usually sparsely hairy and have serrated margins.The flowers are small, inconspicuous, and typically range in color from reddish-brown to maroon or purplish. They are borne in axillary clusters and have five distinct, often star-shaped petals. The fruit is a distinctive, often bristly or warty, globose capsule that splits open to release its seeds.

The genus Ayenia belongs to the subfamily Byttnerioideae within the Malvaceae family. Historically, some members of this group were classified under the former family Sterculiaceae, which is now largely subsumed within a broader Malvaceae concept.Habitat and Distribution
