About

Stylosanthes biflora, known by the common names pencil flower, sidebeak pencilflower, and endbeak pencilflower, is a species of flowering plant in the Fabaceae (legume) family. It is native to the Southeastern United States where it is widespread in open areas of native vegetation. It produces yellow-orange flowers in the summer and fall.

This species is highly variable throughout its range, and numerous species had previously been segregated out of it. However, their morphological differences have been found to be so overlapping that the former segregates are now considered the same species.

Where it grows

The species is native in the United States from Texas to the west, Illinois to the north, New York to the east, and Florida to the south. It is also present in Arizona. Its habitats include sunny and dry areas, such as glades, prairies, savannas, dry upland forests, tops of bluffs, and riverbanks.
