Morphometric study of Euchiton traversii complex (Gnaphalieae: Asteraceae)

Abstract

A morphometric study was undertaken into alpine and subalpine species of Euchiton Cass. (Gnaphalieae: Asteraceae) in the Euchiton traversii species complex in south-eastern Australia and New Zealand. Phenetic analysis of both field-collected and herbarium specimens resolved the following six taxa included: Euchiton traversii (Hook.f.) Holub, Euchiton argentifolius (N.A.Wakef.) Anderb., Euchiton lateralis (C.J.Webb) Breitw. & J.M.Ward, Argyrotegium mackayi (Buchanan) J.M.Ward & Breitw., Argyrotegium fordianum (M.Gray) J.M.Ward & Breitw. and Argyrotegium poliochlorum (N.G.Walsh) J.M.Ward & Breitw. The results support the segregation of the genus Argyrotegium J.M.Ward & Breitw. from Euchiton. E..
