7. BUCXLXiANDXA, Br. 



A tree attaining 80 ft. high. Leaves alternate, cordate-ovate, acuminate, 

 entire, long-petioled ; stipules solitary or in pairs, large, oblong, coriaceous, 

 deciduous. Inflorescence of 2-5-peduncled heads, at first enclosed between a 

 pair of stipules ; flowers adnate by their calyces, about 8 in a head, polygamous. 

 Calyx-tube adnate to the ovary ; limb 5-lobed. Petals in the Q flower linear- 

 spathulate, fleshy, variable in number ; in the $ rudimentary. Stamens 10-14 

 (in the $ r one) ; filaments long. Ovary half-inferior, 2-celled ; styles 2, separate, 

 soon divaricate ; ovules in each cell 6 in two rows. Capsule nearly superior, 

 woody, subglobose, endocarp horny, showing a tendency to separate from the 

 exocarp. Seeds in each cell 6, oblong, trigonous; the upper wingless solid, 

 without any embryo, the lower one in each cell winged fertile.

Branches and adult leaves glabrous. Leaves 3-8 in. -with a cartilaginous edge, 

 quite entire or 3-cuspidate especially in young plants, petiole 1-5 in. glabrous or 

 when young densely silky with brown hairs. Peduncles (at least at first) densely 

 brown silky; as are the young ovaries. The Malayan Liquidambar tricuspis does 

 not differ in the smallest point from Himalayan specimens some of which have tri- 

 cuspidate leaves and sericeous petioles. Cf. Kurz in Flora, 1871, p. 289.

Trees. Leaves alternate, petioled, ovate or oblong, glandular-serrate, per- 

 sistent ; stipules deciduous or persistent. Floivers in dense heads ; heads wrapped 

 by a large bract, males racemose, females solitary. MALE heads a mass of sta- 

 mens with very short filaments, probably representing numerous achlamydeous 

 flowers. Anthers obverse-pyramidal, the valves when young turned in till they 

 reach the connective so that the young stamen is pseudo-4-celled ; dehiscing 

 longitudinally. FEMALE heads of 12-20 flowers; calyces confluent, without 

 limb. Petals (some rudimentary stamens have been taken for petals). Ovary 

 f-inferior, 2-celled ; styles 2, separate, deciduous ; ovules numerous, axile. 

 Fruit-head, globose, harsh. Seeds numerous ; lowest 1-2 of each cell winged 

 fertile, the upper without wing or embryo. DISTKIB. Species 2; extending 

 from East Bengal to China and Malaya.
