Abstract
Lagenophora schmidiae de Lange & Jian Wang ter sp. nov. (Asteraceae) is described, illustrated and differentiated from L. montana Hook.f. The new species was first recorded from Aotearoa / New Zealand in 1974, when it was identified as L. montana. This relatively recent recognition reflects in part the fact that the new species is extremely uncommon, and has often been confused with the superficially similar L. barkeri Kirk, with which it often grows. A conservation status for L. schmidiae of ‘Threatened / Nationally Critical’ using the New Zealand Threat Classification System is proposed, as the new species is known only from small populations, many of which are threatened by alien weed invasion.
Highlights
Lagenophora Cass., nom. et orth. cons. (Asteraceae) is a genus of ca. 25 species (Wang, Bean, 2019), with nine species accepted for Aotearoa / New Zealand (Allan, 1961; de Lange, Rolfe, 2010; Breitwieser et al, 2012)
Lagenophora montana Hook.f., L. stipitata (Labill.) Druce, and L. sublyrata, are considered indigenous being shared with Australia, and in the case of L. sublyrata, Australia, southern Asia (China, India, Sri Lanka), south-east Asia (Thailand), and Malesia (Java, New Guinea)
Subsequent study of Aotearoa / New Zealand plants identified as Lagenophora montana confirmed that those plants were not conspecific with Australian L. montana but rather represented an undescribed, endemic species, which is here described as L. schmidiae
Summary
Lagenophora Cass., nom. et orth. cons. (Asteraceae) is a genus of ca. 25 species (Wang, Bean, 2019), with nine species accepted for Aotearoa / New Zealand (Allan, 1961; de Lange, Rolfe, 2010; Breitwieser et al, 2012). Lagenophora schmidiae (Asteraceae), a critically threatened new species from Aotearoa / New Zealand. Of the Aotearoa / New Zealand species, six are considered endemic following the merger of Lagenophora lanata A.Cunn.
