This is a handsome tree, 40 feet and upwards in height: its wood is 
very hard and valued by the Cinghalese for building purposes. Young 
stems and leaves downy, of a bright-red colour. The dissimilarity in 
the pairs of young leaves is very remarkable, one being flat, single- 
nerved, and soon falling away, whilst the other is five-nerved, has in- 
volute margins, grows rapidly, and is carried up by the elongating stem 
to some distance above the smaller one. Old leaves coriaceous, disti- 
chous, alternate, shortly petioled, 3—4 inches long, 1 inch broad, lanceo- 
late, tapering to a long narrow blunt point: nerves five, strong, parallel. 
Racemes single or in pairs from the upper part of a large scar, which 
extends upwards from the axil of the leaf, pendulous or nodding, 1-15 
inch long, pubescent, eight- to twelve-flowered. Flowers nearly sessile, 
with small bracts, white, 1 line long, pubescent. Calyx of four valvate 
coriaceous green lobes. Corolla of as many small incurved white petals, 
seated on the calyx, split below the middle into subulate lacinim. Sta- 
mens eight, alternately longer and short ; filaments sübulate; anthers 
versatile; pollen minute, elliptical, with a dark central line. Ovary 
inferior, four-celled, with four erect styles and small capitate stigmas ; 
cells with one anatropous ovule, pendulous from the summit of each. 
Fruit coriaceous, grooved, elliptical-ovate, with a narrow top and per- 
sistent calyx, one-celled, with one pendulous seed, which has only been 
collected unripe, but appears to be albuminous and to have an axile 
embryo. : i '
