nerves 8 or 9 pairs, oblique, slightly carving, prominent beneath ; length 
4 to 5 in., breadth 1'75 to 2 in., petiole *5 in. Panicles 4 to 6 in. long 1 , 
stellate-pubescent ; braeteoles caducous. Flowers shortly stalked. Galyx- 
segments minutely toraentose. Petals *5 in. long, pnle tomentose. 
Stame?is 30 to 36, in 3 series, the filaments dilated at the base : anthoi h 
with equal valves. Ovary sericeous, style glabrous. Ripe fruit sub- 
globose, acuminate, pale tomentoso, about 25 in. in diam. ; fruiting-calyx 
forming a cup with a concave short tube embracing the trait, the seg- 
ments spreading, re-curved, the 3 outer 65 in. in length and breadth, the 
2 inner smaller. Heim t " Recherches but les Dipterocarpacees," p. 51,

Leaf-specimens of what appear to be this tree were collected by 
Mr. Wray (Herb, No. 34:!6) in Upper Perak. 
9. Balanocarfus, Beddome. 
Glabrous or puberulous, rarely scabrid, resinous trees, with in- 
conspicuous fugaceons stipuleB. Leaves entire, coriaceous or membran- 
ous, penni-nerved. Floivers secund, sessile or shortly pedicelled. Sepah 
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 infloxed at 
all. Stamens 15, attached to the bases of the petals, in 3 rows ; or 10 
in 2 rows, sub-equal, the filaments much dilated at the base, the connec- 
tive prolonged into a straight apical awn longer than the ovate anther. 
Torus flat. Ovary 3-celled, cells 2-ovuled, ovules collateral. Style 
short. Stigma minute, entire. Fruit oblong or sub- globose, apiculate ; 
the pericarp ligneous or sub-ligneous. Seed solitary, erect ; cotyledons 
fleshy, plano-concave, the larger 2- or 3-lobed, or entire ; the radicle 
prominent. Southern Peninsular India, Malaya. Probably 12 species. 
Leaves glabrous, smooth. 
Leaves ovate-lanceolate or ovate, caudate-acu- 
minate.
