Sacciolepis

Sacciolepis is a genus of plants in the grass family. Cupscale grass is a common name for plants in this genus.
They are widespread in tropical and warmer temperate regions. Many are native to Africa, with others in Asia, Australia, and the Americas.
These species are annual or perennial and may have rhizomes or stolons. The inflorescence is usually a narrow, dense panicle. They generally grow in moist habitat, such as marshes and streambanks. "Sacciolepis" is closely related to genus "Panicum".
