The New Zealand species ofGingidium(Umbelliferae)

Abstract

Gingidium J. R. et G. Forst was reinstated by Dawson (1961) for a group of 11 species, of which some were formerly included in Angelica L. and others in Anisotome Hook f. The present account recognises only five New Zealand species of Gingidium, of which one includes four varieties. The names adopted are: G. montanum J. R. et G. Forst.; G. trifoliolalum (Hook f.) Dawson; G. decipiens (Hook f.) Dawson; G. enysii (Kirk) Dawson var. enysii; G. enysii var. peninsulare J. W. Dawson var. nov.; G. enysii var. spathulatum J. W. Dawson var. nov.; G. enysii var. buxteri; J. W. Dawson var. nov.; G. flahellatum (Kirk) Dawson. Two Australian species, at present known as Seseli algens and Seseli harveyanum, should probably also be included in Gingidium. Generic criteria are discussed and the essentially gynodioecious sexual pattern described. Consideration is given to the status of Anisotome patula (Kirk) Cheeseman, Ligusticum ovutum Wolff and to the putative hybrids G. montanum × decipiens, G. montanum × trifoliolalum and G. montanum × ensii var. peninsulare.
