Caroline Ivory Nutpalm (Metroxylon amicarum)
Description
Usually growing to 20 metres (66 ft), but occasionally over 25 m (82 ft), these massive palms have solitary trunks with widely spaced leaf-scar rings and old leaf bases attached to the top. Leaves are pinnately arranged, 5 m (16 ft) long, on 1-metre (3 ft 3 in) petioles. The lanceolate leaflets are dark green to 1 m (3 ft 3 in) and occur on the rachis at varying angles, creating a plumose leaf. Unlike its monocarpic relatives, this species has a narrow inflorescence which develops within the leaf-bases; the stem is erect until the fruit matures and then sags to a pendent cluster. The single-seeded fruit are 9 centimetres (3.5 in) long, extremely hard, and are covered in brown, glossy scales. Of all species in the genus it is probably the most hardy to cold. It is found only in the Federated States of Micronesia. It is threatened by habitat loss.
