Ehrharta is a genus of plants in the grass family.Thunberg, Carl Peter. 1779. Kongliga Vetenskaps Academiens Handlingar 40: 217, pl. 8[http://www.tropicos.org/Name/40001517 Tropicos, Ehrharta Thunb.]

Most of the species are native to Africa, with others native to the southern Arabian Peninsula, Maluku Islands, Fiji, and New Zealand. Several including Ehrharta longiflora, Ehrharta calycina and Ehrharta erecta have been introduced to parts of North and South America, Europe, India, and Australia, and are considered invasive weeds.{{Cite web |url=http://tncweeds.ucdavis.edu/esadocs/documnts/ehrh_sp.html |title=Element Stewardship Abstracts, Ehrharta spp. |access-date=2006-01-05 |archive-url=https://web.archive.org/web/20051124204420/http://tncweeds.ucdavis.edu/esadocs/documnts/ehrh_sp.html |archive-date=2005-11-24 |url-status=dead }}[http://www.efloras.org/florataxon.aspx?flora_id=2&taxon_id=250071002 Flora of China Vol. 22 Page 181 皱稃草 zhou fu cao Ehrharta erecta Lamarck, Encycl. 2: 347. 1786. ][http://luirig.altervista.org/flora/taxa/floraspecie.php?genere=Ehrharta Altervista Flora Italiana genere Ehrharta][http://bonap.net/NAPA/TaxonMaps/Genus/County/Ehrharta Biota of North America Program 2013 county distribution maps]
