The perennial genus Hystrix (Triticeae) is revised. The genus has been treated very differently by contemporary authors, but here documentation is presented of diagnostic characteristics distinguishing it from genera with which it has been confused. Six species, one divided into three subspecies, are recognized: H. patula, H. californicus, H. duthiei ssp. duthiei, H. duthiei ssp. longearistata, H. duthiei ssp. japonica, H. komarovii, H. coreana, and H. sibirica. A key, descriptions, nomenclature, variation pattern, distribution maps, and cytogenetic data are presented.
