A revision of the New Zealand Kunzea ericoides (Myrtaceae) complex

Abstract. A revision of the New Zealand Kunzea ericoides complex is presented. This paper is the final of a series that has explored the systematics of the New Zealand Kunzea complex using cytological and molecular variation, as well as experimental hybridisations between postulated segregates. As a result of those studies ten species, all endemic to New Zealand, are recognised; seven of these are new. One species, Kunzea triregensis sp. nov., is endemic to the Three Kings Islands and another species Kunzea sinclairii, endemic to Aotea (Great Barrier Island). The North Island of New Zealand has seven species, Kunzea amathicola sp. nov., Kunzea salterae sp. nov., Kunzea serotina sp. nov., Kunzea robusta sp. nov., Kunzea tenuicaulis sp. nov., Kunzea toelkenii sp. nov., and Kunzea linearis comb. nov. Of these, Kunzea linearis, Kunzea salterae, Kunzea tenuicaulis and Kunzea toelkenii are endemic to the North Island, and Kunzea amathicola, Kunzea robusta and Kunzea serotina extend to the South Island which also supports one endemic, Kunzea ericoides. Typifications are published for Leptospermum ericoides A.Rich., Leptospermum ericoides var. linearis Kirk, Leptospermum ericoides var. microflorum G.Simps., Leptospermum ericoides var. pubescens Kirk, and Leptospermum sinclairii Kirk, names here all referred to Kunzea. The ecology, conservation, extent of natural hybridisation and some aspects of the ethnobotany (vernacular names) of these Kunzea are also discussed.
