Urochloa fusca
Also called Browntop Signal Grass, Brown Top Signal Grass
Browntop signalgrass is an annual wild grass native to the Americas, from the southern United States to Paraguay, and now a weed in Australia. It thrives in warm, sunny, seasonally dry conditions and is a grass of disturbed ground rather than a garden ornamental.
Urochloa fusca, the browntop signalgrass, is a wild grass species with a native range extending from Paraguay in South America to the southern United States (Alabama, Arizona, Florida, Georgia, New Mexico, Texas, and Oklahoma), and it is now found as a weed in Australia. The species is diploid, with a base chromosome number of 9, and utilizes the PCK enzymatic subtype of C4 photosynthesis. Based on a molecular phylogeny of the genus Urochloa, the closest relatives of U. fusca are Urochloa arizonica and Urochloa mollis The genome of U. fusca is currently being sequenced by the Joint Genome Institute.
