OF THE DIPTEROCARPACER. 65 
Apparently anomalous. Blanco states stamens more than 30, 
and no style, and this seems to agree with Vidal's figure. The 
fruiting-calyx, however, is said to have 2 wings. Vidal’s n. 84 
(leaf only) has thinly coriaceous lanceolate leaves, perfectly 
glabrous. Sec. nerves 8 pairs, arcuate; tertiary indistinct. 
Domatia on the underside in the axils of second. nerves.

Tertiary nerves faintly visible on both sides of leaf. Flowers 
on pedicels nearly as long as calyx, in unilateral racemes, these 
in racemose panicles. Ovary glabrous; no stylopodium ; style 
short. Fruit loosely enveloped by the base of calyx-segments. 
Embryo channelled outside. Hypocotyl nearly as long as embryo. 
Cotyledons bifid, the outer concave, embracing the inner.
