INDIGENOUS NEW-ZEALAND TRITICEAE - GRAMINEAE

Indigenous New Zealand members of tribe Triticeae are revised. Three genera are accepted: Elymus in preference to Roegneria; Stenostachys in preference to sectional rank in Elymus; Australopyrum in preference to Agropyron or Hystrix. Two new species of Elymus are described; E. solandri is a new combination for widespread indigenous plants. A new species in Stenostachys is described. Australopyrum is as treated recently. Natural hybrids are described, both interspecific and intergeneric. Genome analyses are discussed especially for hexaploid species.
