Hyperthelia dissoluta
Hyperthelia dissoluta, the yellow thatching grass, is a species of flowering plant in the family Poaceae. It is native to SubSaharan Africa and Madagascar. It has been introduced to Mexico, Central America, Colombia, and Brazil. Its palatability to livestock decreases markedly as the plant matures, and it is a very aggressive competitor, so it has developed a bad reputation among ranchers. References
