''Barringtonia edulis'', commonly called cutnut, Fiji nut or borolong, is an accepted tree species native to Fiji and Vanuatu in the south-western Pacific. It is associated primarily with wet tropical conditions and produces a large, single-seeded fruit used as food. <sup id="cite_ref-1">[[#cite_note-1|[1]]]</sup><sup id="cite_ref-2">[[#cite_note-2|[2]]]</sup>

== Description ==

Cutnut is an evergreen tree that can reach about 15 m. It occurs in forests, woodland and grassland to roughly 400 m, and is also grown around homes and villages in its native region. <sup id="cite_ref-3">[[#cite_note-3|[3]]]</sup>

The leaves are glossy and about 25–75 cm long by 8–30 cm wide. Pendulous pink or cream racemes may reach about 65–180 cm and carry roughly 40 flowers. Fruits are egg-shaped to elongated, green, purplish or red, and about 4.5–9 cm long by 2–4.5 cm wide. Each fruit contains one distinctly fissured seed. <sup>[[#cite_note-2|[2]]]</sup>

== Cultivation ==

=== Soil and water ===

In the south-western Pacific the species is associated with wet-tropical forest, woodland and cleared or semi-cultivated settings. A planting site should combine reliable moisture with drainage: institutional care guidance lists moderate water and well-drained soil, so standing water around the root zone is a poor starting condition. <sup>[[#cite_note-2|[2]]]</sup><sup>[[#cite_note-3|[3]]]</sup>

=== Sun and humidity ===

Full sun is listed in the institutional care account, while the botanical horticultural account records success in full sun and partial shade. Bright light is therefore a practical starting point, with partial shade available where intense exposure dries the planting site faster than its wet-tropical moisture regime allows. The native wet-tropical range also favors a humid, well-watered environment rather than a persistently dry one. <sup>[[#cite_note-2|[2]]]</sup><sup>[[#cite_note-3|[3]]]</sup>

=== Seasonal changes ===

Cutnut remains evergreen in its tropical setting. Treat it as a warm-growing tree: maintain moisture while new growth and fruit are developing, but keep drainage open through the wet season. In a site with a pronounced dry period, adjust irrigation to the local wet–dry rhythm instead of using a fixed calendar; this is a climate-based cultivation inference rather than a quantified species limit. <sup>[[#cite_note-1|[1]]]</sup><sup>[[#cite_note-2|[2]]]</sup>

== Propagation ==

Fresh ripe seed is the documented propagation route, and the seed is best sown as soon as it is ripe. Handle the fruit and seed as a fresh lot, recording the collection date and source when comparing germination results. <sup>[[#cite_note-3|[3]]]</sup>

== Flowering, fruiting, and harvest ==

The long, pendulous racemes carry pink or cream flowers. Pollination is listed as involving biotic fauna, and the botanical account lists moths and bats. These records support fauna-associated pollination, but do not establish that every listed animal is an effective pollinator or that one pollinator is required at every site. <sup>[[#cite_note-2|[2]]]</sup><sup>[[#cite_note-3|[3]]]</sup>

The fruits range from green to purplish or red and contain one fissured seed. For propagation, collect ripe fruit and sow the seed promptly rather than treating it as a long-stored seed crop. <sup>[[#cite_note-2|[2]]]</sup><sup>[[#cite_note-3|[3]]]</sup>

== Fruit and uses ==

The seed is documented as edible raw or cooked and is described as having a flavor like raw peanuts. The fruit and seed use records support food use, while the flavor description is an attributed sensory observation rather than a standardized comparison. <sup>[[#cite_note-2|[2]]]</sup><sup>[[#cite_note-3|[3]]]</sup>
