 Leaves coriaceous, oblong, 6-8 in. long, petiole short. PI. in axillary fascicled 

 panicles, shorter than the leaves, petals pubescent outside. Upper portion 

 of ovary puberulous, stylopodium glabrous, slightly verrucose, style short. 

 Round echinate galls frequent in the axils of leaves. 



. Evergreen forests at the foot of the Western Ghats, from North Kanara southwards.

 Kongu, Tarn. ; Veduvdli Kongv, Mai.), Travancore. A large glabrous tree, bark dark, 

 peeling off in long recurved strips, which hang all round the trunk. Leaves ovate, 

 caudate-acuminate, blade 2-4i, petiole slender, £ in. long. -Panicles 2-4 in one leaf 

 axil. Stylopodium cylindric, slightly narrowed at base. Larger segments of fruiting

 siamensis, Miq. ; PL Brit. Ind. i. 304. Vera. Enggin, Burm. 



A large tree, heartwood brown, hard and durable, on dry ridges a shrub. 

 Leafless during part of the hot season, when the tree is covered with large 

 panicles of showy flowers. Leaves ovate, whitish-tomentose beneath while quite 

 young. Fl. f in. across, petals orbicular, at flowering time forming a hollow 

 globe, open at the top, enclosing stamens and ovary. Stamens 15, anthers 

 oblong, cells equal, the valves of each cell, as well as the connective, prolonged 

 into a shortawn, so that each anther has 5 subulate appendages. Ovary glabrous, 

 prolonged in to a conical stylopodium, style filiform, glabrous. All calyx segments 

 enlarged in fruit, but the three outer much larger than the others, all narrowed 

 into a stalk, which expands into a broad base, appressed to the base of fruit, 

 but not enclosing it. Cotyledons thick, fleshy, stipitate, concave, enclosing 

 each other, filled with fat and oil, radicle short, plumula conspicuous. 



Throughout the Eastern Peninsula, extending to 25° N. Lat. Gregarious in Upper 

 Burma and Cochinchina, scattered in the Eng forest of Lower Burma. Fl. H. S. 



5. SHOREA, Roxb. ; PI. Brit. Ind. i. 303. 



Stipules in a few species large and j)ersistent, in most small and early 

 deciduous. Leaves coriaceous, secondary nerves jwominent, tertiary mostly 

 parallel. Flowers as a rule in unilateral spikes or racemes, which are distichous 

 and regularly alternating on the branches of large axillary and terminal 

 panicles. Each flower subtended by 2 bracteoles, mostly deciduous, in a few 

 species persistent and conspicuous, Sepals strongly imbricate, hairy. Petals 

 hairy outside. Anther cells generally equal ; connective as a rule prolonged 

 into a pointed appendage. Segments of fruiting calyx with their broad bases
