Hystrix (plant)

Hystrix was a formerly recognized genus of grass (family Poaceae).
The genus "Hystrix" was created in 1794 by Conrad Moench for the species described as "Elymus hystrix" by Carl Linnaeus in 1753. Moench considered that "E. hystrix" was sufficiently distinct to be placed in a separate genus as "Hystrix patula"; the genus was to be used for species without glumes or with long setaceous glumes. Subsequently a number of other grass species were placed in this genus.
Genomic studies from the 1960s onwards showed that "H. patula" does in fact belong in "Elymus", as this is now defined. Other species placed in "Hystrix" have genomes more closely resembling those of "Leymus" species, and are better placed in that genus. Currently accepted transfers include:
