152 ANNALS OF ROYAL BOTANIC GARDEN, CALCUTTA. 
when open, pedicelled. Calyx-lobes more ог less broadly ovate, acuminate, minutely 
tomentose outside, imbricate, two being quite external. Petals three times as long as 
the calyx, elliptic, spreading, puberulous on one half outside, and glabrous on the 
other, quite glabrous inside. Stamens 15, equal, erect, the filaments short and broad; 
the anthers elongate, narrow, with 5 apical awns, one of which is deflexed and rather 
shorter and thicker than the other four. Ovary ovoid, sub-glabrous, much shorter than 
the filiform style, stigma minute. Ripe fruit ovate, apiculate, 1 in. long, glabrous; 
calyx-wings а'1 enlargel and reticulate except at the base; the three outer narrowly 
oblong, obtuse, and narrowed to the concave base, 9-nerved, 4 to 45 in. long, and 5 
to "75 ia. broad; the two inner lobes much narrower and fewer-nerved, about 2°5 in. 
long, or even shorter. 
Langkani; Curtis, No. 2095. 
The petals of this species are spreading, and the flower has quite an unusual facies for the order. 
It is at once distinguished by its curiously 5-awned anthers. Four of these awns are the produced 
apices of the anther cells, the fifth (the thicker and deflected one) is a prolongation from the соппес- 
tive.

SHOREA, Roxb. 
Glabrous, mealy, or pubescent resinous trees. Leaves entire or sub-repand, pinnate- 
veined; stipules large, coriaceous and persistent, or minute and fugacious. Flowers in 
axillary or terminal, lax, cymose panicles; bracts persistent, caducous, or 0. Sepals 
ovate or lanceolate, imbricate, 3 being external and 2 internal. Stamens 15 or 20, or 
30: anthers ovate or oblong, rarely linear; connective subulate-cuspidate, rarely in- 
appendiculate; valves обвива, rarely cuspidate, equal, or the outer slightly larger. 
Ovary 3-celled, cells 2-ovuled; style subulate, stigma entire or 3-toothed. Fruit with 
leathery, rarely with woody, pericarp, 1-сейей, 1-seeded, closely surrounded by the 
bases of the persistent, usually accrescent, sepals, the 3 outer, or more rarely, all, and 
sometimes none, of which are developed into 7- to 10-veined reticulate membranous 
linear-oblong wings, Cotyledons fleshy, unequal, usually enclosing the superior radicle. 
Disrris.—Tropical Asia and chiefly the Malayan Archipelago; species about 60.

PLATE 185A. 
SHOREA Curtis, Dyer MSS. in Herb. Kew. 
A tree 100 to 150 feet high; young branches slender, at first minutely stellate- 
puberulous, ultimately dark-coloured and glabrous. Leaves coriaceous, oblong-lanceolate 
bluntly acuminate; the base sub-cuneate, or sometimes almost rounded; upper surface 
of young leaves minutely pubescent, of adults glabrescent or quite glabrous, the 
lower uniformly covered with very minute rufescent (young), or pale (adult) tomen- 
tum; main nerves 10 to 14 pairs, ascending, curving slightly, prominent beneath: 
length 3 to 4 in. breadth 1:2 to 1-4 in., petiole *4 to '6 in. Panicles axillary or 
terminal, 15 to 3 in. long; the rachis slender, glabrous. Flowers about "8 in. long, 
in distichous secund rows of 4 or 5, on the short lateral branchlets, enveloped while
