What became of Hystrix?

---

Hystrix Moench was a perennial genus of the Triticeae. Its members differed from those of other genera in
the tribe in lacking glumes. The type species is H. patula Moench, a North American taxon. When it became accepted
that H. patula should be included in Elymus, Hystrix could not be used as a generic name. The problem became how to
treat the other species that had been included in Hystrix. Hystrix patula, like many other species of Elymus, has the StH genomic composition but H. coreana (Honda) Ohwi, H. californica (Bol.) Kuntze, H. duthiei (Stapf) Bor ssp. duthiei,
and H. duthiei ssp. longearistata have the NsXm genomic composition that is associated with Leymus. Using genomic
in situ hybridization analysis, we showed that H. komarovii (Roshev.) Ohwi has an NsEe genomic composition, a
combination not known from any other species. Hystrix sibirica (Trautv.) Kuntze and H. duthiei ssp. japonica are
included in Leymus on morphological grounds. The status of H. kunlunensis K. S. Hao is not clear. In this paper, we
summarize our results and those of others concerning what is now known and the problems that remain concerning the
species that used to be included in Hystrix.

Key words Elymus, GISH, Leymus, morphology, Poaceae, taxonomy.
