''Hyparrhenia rufa'' is a species of grass known by the common names jaragua,〔(''Hyparrhenia rufa'' (Nees) Stapf. ) FAO.〕 jaragua grass, and giant thatching grass.〔(''Hyparrhenia rufa'' (Nees) Stapf. ) Germplasm Resources Information Network (GRIN).〕 It is native to Africa and it is widespread in the world as a cultivated forage and fodder for livestock and a naturalized and sometimes invasive species.〔
==Description==
This is usually a perennial grass, but it sometimes grows as an annual,〔(''Hyparrhenia rufa''. ) Pacific Island Ecosystems at Risk (PIER).〕 and it is variable in form.〔 It usually forms dense tufts of stems from a short rhizome.〔Heuzé V., et al. (2012). (Jaragua (''Hyparrhenia rufa''). ) Feedipedia.org. A programme by INRA, CIRAD, AFZ and FAO. Updated 2012.〕 The stems can be 30 centimeters to 3.5 meters tall.〔Barkworth, M. E. (''Hyparrhenia rufa''. ) Grass Manual. Flora of North America.〕 The leaf sheaths enclose the stem at intervals, making it appear banded.〔 Flowering stems have sparse leaves,〔 but grazing increases leaf production.〔(''Hyparrhenia rufa''. ) NatureServe. 2013.〕 The leaf blades are 30 to 60 centimeters long. The panicle is up to 80 centimeters long and is made up of many short, yellowish or red-tinged racemes all subtended by a narrow, reddish spathe a few centimeters long. The racemes are lined with pairs of spikelets, the red-haired fertile spikelets without stalks and the smaller sterile spikelets on stalks.〔
The rough-haired seeds are dispersed in the fur of animals,〔 on the wind, and on vehicles and machinery such as graders.〔
