Craspedia huriawa (Compositae/Asteraceae, Gnaphalieae), a new species from Nelson/Tasman, South Island of New Zealand

Abstract

ABSTRACT Our research towards a revision of New Zealand Craspedia (Compositae/Asteraceae, Gnaphalieae) led to the recognition of a new species from Nelson/Tasman, South Island of New Zealand. Craspedia huriawa occurs only in the area of the Riuwaka River North Branch at the base of Tākaka Hill, Pikikirunga Range. It is morphologically similar to C. minor but is distinguished by its sturdier scapes, oblanceolate to almost linear leaves, glomerules changing gradually from hemispherical to globose after anthesis, larger and more numerous florets (c. 200 per glomerule), clavate apical pappus bristle plumes, longer twin trichomes of the achene, and pappus-to-achene length <2.1:1. We are providing the formal taxonomic treatment together with illustrations and descriptions of its morphology, distribution, habitat, ecology, phenology, and etymology, as well as an assessment of its conservation status.
