==Description==
Metroxylon salomonense is a solitary-stemmed palm, growing up to 25 metres tall. The un-branched stem can be 25 - 55 cm in diameter, topped by a rosette of leaves that can each be 7 metres or more long. A very important tree for the local economy of native people, providing them with food, medicines and a wide range of other materials. The hard seeds are exported to Alaska, where the Inuit carve them in place of sea-mammal ivory.

A very large and immensely fast growing palm from New Guinea and the Solomon Islands with a thick trunk to 20 m (66 ft.) tall and an erect crown of leaves arching at the tip. The baseball-sized fruits have scaly, snakeskin-like appearance and are produced on a large, terminal inflorescence. (RPS.com)

A plant of the humid, tropical, lowland forests, able to succeed at elevations up to 700 metres. It prefers a mean annual rainfall in the range 2,000 - 5,000 mm, and does not tolerate more than a short dry period. It prefers a mean annual temperature of around 25°c with a minimum of 17°c. It is not tolerant of frost, though it can succeed in cooler areas of the tropics such as Hawaii, but then grows more slowly. Prefers a relatively sunny position. Succeeds in a wide range of soils, preferring medium to heavy soils with somewhat impeded drainage. It can persist on well drained, poor quality materials including sand, clay, or 'aï' lava. It will grow in soil that is periodically inundated by salt water as long as fresh water flow is more prevalent. Plants are not very tolerant of water shortage, but nor do they like inundation for more than short periods. Succeeds in a wide range of pH, from 4 - 7.4. Plants are tolerant of strong, salt-laden winds. Plants usually take 12 - 15 years to come to flowering maturity from seed, though in ideal conditions this can be reduced to about 10 years. A monocarpic species, they only flower once and then die.
