Description:  "This clustering species can have up to a dozen trunks per plant, each of which can attain a height of 30 feet.  The trunks are green in their newer parts and grayish in their older parts, diaphanously thin and elegant, and are never more than 3 inches in diameter, encircled with widely spaced whitish circles of leaf base scars.  The crownshaft is 3 to 4 feet high, smooth, and green, and barely bulging at its base.  The leaves are similar to those of betel-nut palm but usually darker green and with larger fused terminal leaflets; there are generally no more than six leaves per trunk.  The palms are monoecious with both male and female flowers in each inflorescence, the latter emerging from beneath the crownshaft.  The tiny, greenish white, fragrant blossoms produce clusters of 1-inch-wide, ovoid, brownish orange to reddish orange fruits. The species varies mainly in the ultimate height of the trunks and the amount of suckering, there are even some individuals with solitary trunks"  (Riffle & Craft, 2003; pp. 255-256).

Habitat/ecology:  "This palm does not tolerate frost.  It requires partial shade when young but, as an adult, can withstand full sun, even in hot climates.  It is also a true water lover and needs a rich, humus-laden, friable soil with unimpeded drainage"  (Riffle & Craft, 2003; pp. 255-256).

Propagation:  Seeds and suckers  (Riffle & Craft, 2003; pp. 255-256).

Native range:  "Wet regions at low elevations in eastern India, Southeast Asia, eastern Indonesia and the Philippines"  (Riffle & Craft, 2003; pp. 255-256).
