This tree is a native of Sumatra and Borneo. It is stated by 
Mr. Prince, to grow spontaneously in the forests, and to be found in 
great abundance from the back of Ayer Bongey, as far north as 
Baeougan, a distance of two hundred and fifty miles. It is classed 
among the tallest and largest trees that grow on the coast, frequently 
measuring from six to seven feet in diameter; but the trees are many 
years of age before they acquire that size. The trunk rises to a great 
height, is arboreous, and covered with a brownish bark ; the leaves 
are from three to seven inches long, and from one to two broad, 
elliptic, obtusely acuminate, entire, parallel veined, smooth, and 
stand upon short petioles, with subulate, caducous stipules, in pairs; 
the lower leaves are opposite, the upper ones alternate ; the perianth 
is persistent, one-leaved, divided at the border into five foliaceous, 
spatulate, rigid reflex wings ; the capsule is superior, ovate, woody, 
fibrous, finely streaked with longitudinal furrows, embraced at the 
base by the calycine, hemispherical cup of the perianth, and sur- 
rounded by its enlarged leaflets : one-celled, and three-valved ; the
