摘要
The species group previously known as Hebe 'Paniculatae' is segregated as a new genus, Heliohebe. The new genus is characterised by a number of unique synapomorphies, and does not share apomorphic character states with Hebe, Parahebe, Derwentia, or Chionohebe. It appears to have arisen early in the radiation of the New Zealand Veroniceae. Five species are recognised: H. hulkeana with two subspecies, H. lavaudiana, H. pentasepala, H. raoulii with two subspecies, and H. acuta. H. acuta is a new species and H. pentasepala was formerly treated at varietal rank under Hebe raoulii. H. acuta is quite similar to H. raoulii, but has smaller, more intensely coloured flowers, and the anterior calyx lobes are free. It grows sympatrically with H. hulkeana subsp. hulkeana, H. pentasepala, and H. raoulii subsp. raoulii. Keys, synonymy and typification, descriptions of all taxa, distribution maps, and a cladistic analysis of Heliohebe are presented.
