OF THE DIPTEROCARPACEX. 115 
embryo, of which he gives a somewhat different description. A 
section, however, through the seed near the base of the fruit 
shows both cotyledons divided into numerous lobes. The 
anatomieal characters relied upon by Heim do not seem to 
me to be of sufficient importance to separate this species from 
Cotylelobium.

A small tree; sap-wood very thin, white; heart-wood very 
hard and close-grained, light yellowish brown when fresh, quite 
black when dry and seasoned, with a slight hue of glossy brown. 
Next to Dryobalanops, perhaps the most valuable tree in

Branchlets, petioles, and underside of leaves densely clothed 
with minute stellate hairs. Leaves thickly coriaceous, elliptic 
lanceolate, shining above, opaque beneath; secondary nerves 
very numerous, indistinct ; blade 3-5, petiole $ in. long. Flowers 
3 in. long, racemose in terminal and lateral panicles, the ramifica- 
tions of which, like the calyx, are grey-tomentose. Petals oblong, 
almost glabrous. Anthers linear, hispid; valves unequal 
connective prolonged into a short and often bent mucro; 
filaments short, scarcely dilated at base. Ovary tomentose, as 
well as the thickened basis of style, which is long cylindric ; with 
a slightly broader and indistinctly 3-toothed stigma. Fruit 
tomentose, globular, the three smaller segments of fruiting-calyx 
linear-lanceolate, acute, š in. long, the two larger obtuse, 
narrowed below, 2 in. long.
