The taxonomy of Haastia (Compositae : Asteraceae)

Abstract

The taxonomy of the genus Haastia is investigated in preparation for a formal revision. Morphological and anatomical character states are analysed using numerical phenetic techniques; biochemical, ecological and geographical information is also utilised. Two new taxa are proposed; one new species and a new variety of Haastia sinclairii. It is recommended that Haastia pulvinaris var. minor be promoted to the rank of species. All other taxa should retain their current status. Natural hybridisation is discussed. All taxa are keyed and described.
