 Stame7is 30 to 36, in 3 series, the filaments dilated at the base : anthers 

 vpith equal valves. Ovary sericeous, style glabrous. JSipe fmit sub- 

 globose, acuminate, pale tomentose, about "25 in. in diam. ; fruiting-calyx

Pahang : Ridley, No. 2626. Distrib. Bangka, Borneo. 



Leaf- specimens of what appear to be this tree were collected by

9. Balanocarpus, Beddome. 



Glabrous or puberulous, rarely scabrid, resinous trees, with in- 

 conspicuous fugaceous stipules. Leaves entire, coriaceous or membi-an- 

 0U8, penni-nerved. Floivers secand, 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 I'ound 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. 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 fiat. 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 

 fieshy, 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.
