N2  - In Australia, the genus Elymus L., as currently interpreted, includes two species: E. scaber (R.Br.)&#193;.L&ouml;ve &#91;with two varieties E. scabervar. scaber and E. scaber var.plurinervis (Vickery) B.K.Simon&#93;; andE. multiflorus (Hook.f.) L&ouml;ve &#38; Connor. A thirdspecies, apomictic E. rectisetus (Nees)&#193;.L&ouml;ve &#38; Connor, which is naturalised in New Zealand from Australia has not been included in Australian regional Floras except as asynonym of E. scaber. A preliminary phenetic analysis ofmorphological characters of 19 specimens and reports on recent work indicatethat at least four major entities exist: short-awnedentities (E. scaber sensu Labillardi&egrave;re);long-awned apomictic entities (sensu E. rectisetus);long-awned entities with large glumes (E. scaber var.plurinervis); and very short-awned entities(E. multiflorus). In a study of seed set, long-awnedentities of E. scaber exhibited relatively low seed set(12&#8211;26%), a reported feature ofE. rectisetus. The results, taxonomy, and recent studiesof the reproductive biology, geo- graphic distribution and genome constitutionof taxa of Elymus common to Australia and New Zealandare discussed, and a revision of the current taxonomic ranking is suggested
