* 302. (1) D. levis (Ham. :) young branches compressed, 2-edged: leaves 
ovate or oblong-ovate, retuse at the base, acute, shining on both sides, with 
numerous prominent veins: petioles glabrous: tube of the enlarged calyx 
slightly ventricose but scarcely contracted below the limb, even (without an- 
gles) : capsule ovate, even.— Ham. in Wern. Soc. Trans. 6. p. 299.—D. turbi- 
natus, Roxb. Cor. 3. t. 213; fl. Ind. 2. p. 612; Wall. L. n. 952. a. 
* 303. (2) D. turbinatus (Geertn.:) young branches terete: leaves ovate, 
acute, pubescent on both sides, but particularly towards the margin, with nu- 
merous slightly prominent veins: petioles pubescent: tube of the enlarged 
calyx turbinate, much contracted below the limb, even (without angles) : cap- 
sule ovate, marked with 6 (occasionally 8) furrows.—Gertn. fr. 3. p. 51. t. 
188; Ham. in Wern. Soc. Trans. 6. p. 399 ; Moon? cat. Ceyl. pl. p. 42.—Ca- 
ryolobis indica, Gertn.? fr. t. 45. ` pu 
This species yields almost no oil, and is used in Chittagong for the con- 
struction of litters: D. lævis yields abundance of oil. 
IV. HOPEA, Roxb. 
Sepals 5, two or sometimes three of them afterwards enlarging into long 
wings. Corolla of one piece (gamopetalous) ; tube campanulate ; segments 
of the limb oblique, linear, oblong, spreading, twisted. Stamens 15: filaments 
10, alternately simple and bifid: anthers 15; cells short, obtuse ; connecti- 
Yum produced beyond the cells into a longish deciduous bristle. Ovarium 
3-celled, with two pendulous ovules in each cell. Seed solitary: radicle su- 
perior — Trees, Leaves entire, often with glands in the axils of the nerves. 
Panicles axillary or terminal, composed of alternate bifarious ramifications. 
Flowers small, yellow, fragrant, secund and nearly sessile on the branches of 
the panicle. j 
Dammara Selanica, Rumph. Amb. 2. p. 168. t. 56, or Unona ? Selanica, DC. prod. 
l. p. 96, certainly belongs to this genus, notwithstanding it differs from all the other 
*pecies by 3, not 2, of the sepals becoming enlarged. 
304. (1) H. Wightiana (Wall.:) leaves ovate-oblong, obtuse, glabrous: 
branches of the panicle and calyx glabrous : two of the segments of the fruc- 
erous calyx expanded into wings, oblong, obtuse: capsule oblong-ovate, 
acute.— Wall. ! L. n. 6295 ; Wight ! cat. n. 961. 
305. (2) H. glabra (W. & A. :) young branches and petioles glabrous: 
leaves oblong, acuminated, without glands in the axils of the nerves beneath: 
Panicles axillary and terminal, several together, longer than the leaves, gla- 
brous; peduncles compressed.— Wight ! cat. n. 360. 
; Specimens are exceedingly imperfect, but we can scarcely refer them 
to H. Wightiana, although in the absence of fruit the chief difference lies in 
the glabrous, not pubescent, young branches, and much narrower leaves. __ 
ORDER XXVIII. TERNSTR(OEMIACEJE. Mirb. 
Sepals 3-5, concave, coriaceous, persistent, the innermost often the 
gest: wstivation imbricated. Petals hypogynous or very rarely (in 
eya) perigynous, 5 (rarely more or fewer), often combined at 
the base, alternate with the sepals. Stamens inserted with the petals, 
indefinite : filaments often cohering at the base into 1 or more parcels, 
and united to the petals. ` Ovary ovate, plurilocular, usually sessile on 
a discoid torus: ovules 2 or more in each cell; styles 2-7, distinct or
