62 SIR DIETRICH BRANDIS—AN ENUMERATION 
inside; in flower the two outer larger. Ovary, stylopodium, 
and style glabrous; stylopodium cylindric (fig. 4); ovules with a 
long pointed beak (fig. 3).

(1877) 329 ; Pierre, Fl. For. Cochinch. fasc. 16, t. 246. 
Cochinchina. 
Leaves silvery grey beneath. Secondary nerves straight, 
14-16 pairs ; tertiary nerves indistinct. 
Structure of embryo like H. odorata, according to Pierre.

Penang. 
Very short intermediate nerves between the 16 pairs of 
secondary nerves; tertiary nerves distant, parallel and reticulate. 
Fruit tightly enclosed by the thickened base of sepals; pericarp 
thick, woody at apex, splitting into 3 valves, each bearing in the 
middle the traces of a dissepiment. Embryo, as far as can be 
judged from seeds, apparently not fully mature, different from 
other species of Hopea. Hypocoty] free, short, not enveloped by 
cotyledons, these fleshy, but folded, erect, both directed towards 
the base of the seed, one bifid to base, the other emarginate. 
Cells chiefly filled with starch.

Mergui, 60 miles inland (Helfer, n. 716). 
Resembles H. nervosa, King, but differs in its tomentose 
branchlets, leaves with cordate unequal-sided base, no inter- 
mediate secondary nerves, and the tertiary nerves parallel and 
approximate. Flowers pedicelled, in terminal panicles. Sepals 
unequal in flower, the 2 outer longer. Anthers on long broad 
filaments ; appendage of connective longer than twice the anther 
(fig. 1). Ovary with the short broad stylopodium and the short 
style glabrous (fig. 2). Fruit unknown. 
Somewhat similar, but with tertiary nerves reticulate, are 
leaves collected by Sulpiz Kurz on South Andaman Island, and 
marked by him Hopea suavis, a name which is not found either 
in his Andaman Report 1870, nor in his contributions towards 
a knowledge of the Burmese Flora, Journ. Asiat. Soc. Bengal, 
xliii. pt. ii. 1874.
