158 ANNALS OF ROYAL BOTANIC GARDEN, CALCUTTA. 
BALANOCARPUS, Beddome. 
fat. Ord, Dipterocarpec. 
Glabrous or puberulous, rarely scabrid, resinous trees, with inconspicuous fugaceous 
stipules. Leaves entire, coriaceous or membranous, penni-nerved. Flowers secund, sessile 
or shortly pedicelled. Sepals distinct or united at the base, imbricated, two quite external 
to the others; in fruit sub-equal, only slightly enlarged, woody, thickened, and forming 
a 5-lobed cup round the base of (but rarely enveloping) the fruit, not adnate to it and 
never expanding into wings. Petals elliptic, obliquely acuminate, the apices slightly 
inflexed in bud or not inflexed at all. S/amens 15, attached to the bases of the petals, in 
З rows, or 10 іп 2 rows, sub-eqval, the filaments much dilated at the base, the connective 
prolonged into a straight apical awn longer than the ovate anther. Torus flat. Ovary 
3-celled, cells 2-ovuled, ovules collateral. 8/46 short. Stigma minute, entire, Fruit 
oblong or sub-globose, apiculate; the pericarp ligneous or sub-ligneous. Seed solitary, 
erect; cotyledons fleshy, plano-eoneave, the larger 2- or 3-lobed, or entire; the radicle 
prominent. Distrib.—Southern Peninsular India, Malaya ;—probably 12 species.

Batanocarpus CURTISII, King in Journ. As. Soc. Bengal, for 1898, pf. 2, p. 181. 
A tree 20 to 30 feet high; young brances slender, the bark dark-coloured, puberulous. 
Leaves membranous, ovate-lanceolate, bluntly caudate-acuminate, the base slightly cuneate; 
both surfaces glabrous, dull; main nerves 8 to 10 pairs, spreading, faint and scarcely more 
prominent than the secondary nerves; length 2 to 95 in., breadth "75 to 1°15 in., petiole 
`1 to '15 in. Panicles axillary and terminal, shorter than the leaves, glabrescent, lax, 
each with а few 3- to 5-flowered spreading branches. Flowers secund, shortly pedicelled, 
15 in. long. Sepals distinct, sub-equal, thick, rotund-ov ate very obtuse, puberulous out- 
side, glabrous inside, the edges slightly ciliate. Petals elliptic, ob'iquely shortly and 
bluntly acuminate, glabrescent inside, partiy puberulous and partly glabrous outside. 
Stamens 15, in 3 rows, sub-equal; the filaments slightly longer than the anthers, dilated: 
anthers broadly elliptic, teuncate, the connective produced into an apical awn longer than 
the stamen. Ovary cylindric, truncate, glabrous, the style short and stigma minute. Fruit 
smooth, globular, apiculate, crowned by the sub-sessile discoid stigma, enveloped by, but 
not adherent to, the slightly thickened sepals, :25 to '3 in. in diam. (calyx included).
