''Rhopaloblaste ceramica'' Is found on; Maluku, and New Guinea. Widespread from Halmahera and Buru in the Moluccas through to Ceram, then to mainland New Guinea. In Papua New Guinea, known only with certainty from Sandaun and East Sepik Provinces in the north-western part of the country. However, the lost type of the dubious synonym R. dyscrita originates from Morobe Province in the east. Well drained lowland to lower montane primary rain forests. In secondary rain forests it is found in old garden areas, on broken coral to deep, loose, porous, black volcanic soil. Also on alluvial flats in deep clay soil. From 35 to 900 m above sea level. (R. Banka and W.J. Baker. 2004)/Palmweb.

Description

Robust, canopy, solitary palm bearing up to 15 - 17 leaves in the crown. Stem to 35 m tall, 15 - 29 (- 35) cm in diam.; surface slightly rough, brownish grey leaf scars prominent; internodes 12 - 14 cm basally, decreasing to 1 cm distally.

Staminate flower symmetric, greenish, 6.5 - 7 mm long, 6.5 - 6.8 mm in diam. at anthesis; sepals 3 - 3.1 x 3.1 - 3.3 mm, broadly elliptic; petals 6 -6.5 x 6.5 - 6.7 mm, broadly elliptic, glabrous; stamens 3.3- 4 mm long, filaments 2- 2.5 mm long, connate at the base, yellowish, anthers 2.1 - 2.3 mm long, 0.9 - 1 mm in diam., elliptic; pistillode conical, 2.3 - 2.5 mm long, 1.2 - 1.3 mm in diam.

Fruit 30 - 35 mm long, 16 - 18 mm in diam., asymmetric ellipsoid-ovoid, yellow when immature, becoming red at maturity; cupule of persistent perianth 11 - 12 mm long.

Rhopaloblaste ceramica is the largest of all the species in the genus and is easily distinguished by its large asymmetrical fruits, with a substantial cupule of persistent perianth, and the inflorescence branched to three orders with very robust rachillae. Rhopaloblaste ceramica was the first of the species of Rhopaloblaste to be described, based on material collected in 1860 by Teijsmann and de Vriese from Ceram in the Moluccas. Miquel originally placed it in the genus Bentinckia as B. ceramica Miq. Ten years later it was moved to Cyrtostachys (C. ceramica (Miq.) H. Wendl.). In describing the genus Rhopaloblaste in 1876,

Comments and Curiosities

Uses: The shoot apex is edible. The wood is used for arrowheads and floorboards for houses. Occasionally cultivated as an ornamental.

"Attractive sillouhette palm from the Mollucas islands, where it grows to 60' tall.. has 10' leaves with 3' long pendant leaflets. Crownshaft supposedly silver, but who can tell, the palms are so tall." (Geoff Stein)

Rhopaloblaste ceramica; Tropical rainforests on the island of Ceram in eastern Indonesia are home to this elegant, slender palm that sports a smooth, trunk to about 15 m (50 ft.) tall, a long crownshaft and stiffly spreading leaves with long, pendulous leaflets. It is an easy and fast growing palm for the tropics and quite popular in cultivation in southern Asia. (RPS.com)
