Three new species of Gingidia (Apiaceae: Apioideae) from Australia and New Zealand segregated from G. montana

Abstract

Three new species of Gingidia (Apiaceae: Apioideae) segregated from the G. montana (J.R.Forst. & G.Forst.) J.W.Dawson complex are named, with G. montana now regarded as a New Zealand endemic. The new Australian endemic, G. rupicola I.Telford & J.J.Bruhl, is restricted to the eastern escarpment of the New England Tableland, New South Wales. With few populations and limited numbers of plants, the conservation assessment of G. rupicola is Endangered. G. haematitica Heenan is described as a new species from North-West Nelson, South Island, New Zealand, where it is restricted to base-rich substrates in the Burnett Range. Because of its restricted distribution and the continued mining for dolomite at the site of the largest population, G. haematitica is considered to have a conservation assessment of Nationally Critical. The second New Zealand endemic, G. amphistoma Heenan, is known from alpine habitats in the Southern Alps, South Island. Distributions of the three new species are mapped, habitats noted, and a table compares attributes of these species and G. montana.
