Key FeaturesBushy shrub or gnarled tree to 8m. LEAVES in terminal clusters, opposite with adjacent pairs at right angles (=decussate), oval to 6x3cm, thick and leathery, edge smooth, tip obtuse, base obtuse; stalk to 4mm. FLOWERS terminal clusters, c.25, in 1-3 per stalk; petals 5, red, small, 2x3mm(WxL); stamens c.30, long to 15mm, crimson; style undivided, 15mm long. FRUIT 5mmØ, ripens grey, with 3 seeds.

General NoteA widespread and variable genus that has been the subject of much confusion at the species and subspecies level. The Fiji flora of 1985 has three subspecies of Metrosideros collina distributed from Vanuatu to the Societies, while the Hawaiian flora omore...f 1990 lists five endemic species of which one, M. polymorpha has eight subspecies. Genetic analysis of Metrosideros in 2000 cast a new light on the genus. It suggested that the tropical Pacific species arose as a result of at least three separate colonisation events from New Zealand species. It showed that the five species of Hawaii, along with those of Tahiti, Rarotonga and Kermadecs are all nearly identical with NZ's M. excelsa (Pohutukawa); and that they colonised in one or more events in relatively recent times, possibly during the various Ice Ages when strong westerly winds prevailed carrying wind-borne seeds into eastern Polynesia. They also suggested that the M. collina of Vanuatu, Fiji and Samoa had a different and earlier origin than the collina of Eastern Polynesia. of Eastern Polynesia. of Vanuatu, Fiji and Samoa had a different and earlier origin than the collina of Eastern Polynesia. of Eastern Polynesia.
