Abstract
The inflorescences and internal and external features of the flowers and fruits of the 11 New Zealand species of Metrosideros are illustrated and a table and explanatory notes provided to show how the species can be arranged as follows: Group A, sub-group 1: M. excelsa, M. kermadecensis, M. robusta, M. umbellata; sub-group 2: M. perforata; Group B: sub-group 1: M. colensoi, M. diffusa, M. carminea, M. albiflora; sub-group 2: M. fulgens, M. parkinsonii. Groups A and B are chiefly distinguished by open v. closed inflorescences, semi-superior v. inferior ovaries, and seed release through the free part of capsule v. seed release partly through the fused parts of capsule and hypanthium; sub-groups Al and A2 by axillary v. terminal inflorescences, broad v. narrow cymule bracts, and persistent v. deciduous petals; sub-groups B1 and B2 by bulging v. not bulging ovaries at the capsule stage and not persistent v. persistent capsule veins.
