Oreoporanthera, a New Zealand "endemic" plant genus discovered in Tasmania

Abstract

Recent collections near Mt Anne in southwestern Tasmania have extended the known range of the previously monotypic New Zealand endemic genus Oreoporanthera to this island. The Tasmanian plants differ from New Zealand's O. a/pina in a number of floral and vegetative characters and are considered to represent a new species 0. peta/ifera. Like O. a/pina, O. peta/ifera is found on calcareous montane outcrops and the two are clearly closely allied.
