Geographical Distributions

Corypha utan occurs wild and cultivated from India (Assam, An­dam an Islands), Sri Lanka and Bangladesh throughout Southeast Asia to tropical Australia.

Description

Corypha utan is a robust, solitary, one-stemmed and bisexual palm that can reach up to 10-30 m tall. Its stem is erect, columnar, measures 35-75 cm in diametre, unarmed and closely ringed with leaf scars.

The leaves are crowded which form a large crown, early withering and tend to abscise under their own weight. The petiole is robust, measures 2-5(-7) m long, deeply furrowed and with sharp-toothed margins. The blade is orbicular, costapalmate, measures 1.5-3.5 m in diame­tre, and regularly divided to about half of its radius into 80-100, single-fold and linear segments.

The inflorescence is massive, terminal, much-branched and 3-6 m long. The whole inflorescence bears up to 10(-60) million flowers. The flowers are bi­sexual, with tubular sepal, 3-lobed and about 1.5 mm long. There are 3 boat-shaped petals about 3 mm long, white and fragrant. There are 6 stamens, about as long as the petal and with narrowly triangular filaments. The pistil is with 3­-grooved, 3-celled ovary, short style and 3-dentate stigma.

The fruit is a berry-like drupe, nearly globular, measures 2-3.5 cm in diametre, olive-green, with fleshy pericarp, membranous endocarp and it is on a stalk 3-5 mm long. The seed is spherical, measures 1-1.5 cm in diametre hard and with remote-­tubular germination.

Ecology / Cultivation

Corypha utan palms are mostly associated with human settlements. In the wild, they are probably a feature of open seral communities such as alluvial plains or coastal forests, and they do not occur in climax tropical rainforests. C. utan com­monly grows in lowland open locations, rarely above 400 m above sea level. In Java, it is found in open locations, especially grasslands, up to 200 m altitude, but not along beaches or in mangroves. In Malaysia, it is common in the open country in the north. Flowering seems to be induced by long dry periods.
