Metrosideros collina is a species of flowering plant in the family Myrtaceae. It is a tree or shrub native to French Polynesia, the Cook Islands, and the Pitcairn Islands.[1]
The species was first formally described by botanist Johann Reinhold Forster and his son Georg Forster in 1776. It was given the name Leptospermum collinum.
M. collina was formerly thought to have a larger range, extending to Vanuatu, Fiji, and the Samoan Islands. A phylogenetic study, published in 2015 by Pillon et al., found that M. collina comprised two genetically distinct groups, and the populations in Vanuatu, Fiji, and Samoa were recognized as a distinct species, M. vitiensis.[2]
In the Society Islands, Metrosideros collina is a common canopy tree in montane rain forests above 300 meters elevation, and in cloud forests from 400 to 1000 meters elevation, and on exposed ridges.[3]
In the Marquesas Islands, Metrosideros collina is common on drier and more exposed montane forests, in cloud forests, and in shrub form in windswept mountaintop shrublands.[4]
On Rarotonga in the Cook Islands, Metrosideros collina is the dominant tree in cloud forests on the island's cloud-shrouded peaks and ridges above 400 metres elevation. M. collina and associated trees, including Pterophylla samoensis, Elaeocarpus floridanus, and Pittosporum rarotongense, form a low forest canopy averaging eight meters tall. In wetter areas and at higher elevations Ascarina diffusa is often co-dominant or dominant in the canopy. M. collina is also found in lower-elevation rainforests dominated by Homalium acuminatum.[5]
Metrosideros collina is a common canopy tree in higher-elevation interior forests on Pitcairn Island, with the trees Homalium mouo, Ficus prolixa, Pandanus tectorius, and Thespesia populnea.[6]
There are two accepted varieties:[1]
Cultivars of Metrosideros collina are used as ornamental plants, for planting in tropical and subtropical climate gardens. Cultivars include:
