A title derives from either a Greek metra or "heartwood" & sideron or even "iron". There are some fifty metal money of Metrosideros, within 2 subgenera: Mearnsia (Two dozen mintage) & Metrosideros (Twenty-six coinage). Possibly a right-known metal money come a Pohutukawa (Metrosideros excelsa), Northern Rata (M. robustus) & Southern rata (M. umbellatus) of Up to date Zeal&, and M. polymorpha or ‘Ōhi‘the lehua from either a Hawaiian Islands. Up to date Caledonia has vii endemic species of Metrosideros, Hawai‘i has 5, & Future Zealand iv. There exists of these mintage described from either South Africa.

Metrosideros seeds potty disperse on the wind, which accounts for their wide distribution from either the presumed origwithin in Just released Zealand. How else a genus reached Hawai personally‘i appears puzzling because a prevailing Trade blow from either a East. Nonetheless high altitude wind system can use brought seeds northerly from either a Marquesas Islands, which molecular evidence suggests when a origin of the Hawaiian mintage from either one colonizing event.
