138 LXXV. RUBIACEX. (J. D. Hooker.) [ Inora, 
other leaves 5-9 by 11 to 3 in., narrowed into a very short petiole 1-1 in., palo when 
dry, very coriaceous; nerves 15-20 pair, slender, arching ; stipules broad with very 
short points. Cymes 2-4 in. diam., sometimes almost capitate, quite glabrous ; flowers 
white, sweet-scented, sometimes 9-merous ; bracts and bracteoles long, filiform. Calyx 
- 4-g in. Corolla 3 in. across the narrow obtuse lobes. Anthers sessile. Stigma fusi- 
form or 2-fid, with short arms. Fruit i-j in. long, ellipsoid or oblong, straight or 
oblique, crowned with the slender ealyx-teeth.— The extreme forms are the Sikkim, with 
5-merous flowers and very small orbicular floral leaves; and Upper Assam ones, with 
these sometimes 20 in. long and 7 broad. Griffith's Bhotan speeimens (Kew Distrib. 
2983) have calyx-teeth sometimes hardly longer than the tube.

‘cymes pubescent, branches slender, leaves short-petioled lanceolate or linear-lan- 
ceolate subacute, nerves very slender, cymes sessile or peduncled corymbiform 
or brachiate, branches slender, calyx-teeth oblong-lanceolate much longer than

An erect shrub with “ ash-coloured branches and pendulous slender green branch- 
lets with compressed joints” (Roxb.). Leaves spreading, 5-7 by 3-2 in., quite smooth 
and rather shining on both surfaces, pale and reticulate when dry; nerves numerous, 
slender, often almost horizontal; base rounded or aeute; stipules short, with long

erecto-patent ; bracts and bracteoles oblong-lanceolate, caducons, Calyx } in. long, 
glabrous, with 2 erect appressed braeteoles; teeth linear-oblong or lanceolate. 
Corolla white, $ in. across the narrow lobes, Filaments slender. Stigma slender. 
Fruit globose or didymous, calyx-tecth persistent. —In W. & A. Prodr. is a var. B, 
founded on Wight's n. 131F, and described as having oblong-laneeolate leaves some- 
times pubescent beneath; I do not find the latter character on Wight'sspeeimens, Z. 
Wallichii of Wight's Herbarium is not the plant deseribed under that name in the 
Prodromus, not having leaves pubescent beneath, but a slight variety of J, lanceolaria 
with narrower bracts and elliptic-lanceolate leaves. 
3. I. calycina, Thw. Enum. 155; glabrous, leaves subsessile ovate ob- 
long or orbieular obtuse or acute, base acute rounded or cordate, nerves hori- 
zontal, cymes subsessile corymbiform contracted dense-flowered, calyx-teeth 
lanceolate much longer than the ovary, corolla $ in., lobes ovate acute, mouth 
glabrous. Bedd. Ic. Pl. Ind. Or. t. 97. 
Cryton ; Central Province, ascending to 7000 ft., Macrae, Walker, &c. 
A small tree. Leaves 13-3 in., coriaceous, midrib stout, dark brown and reticu-

4. I. Thwaitesii, Hook. f.; glabrous or shoots and cymes pubescent, 
leaves short-petioled oblanceolate oblong or elliptic acute flat or undulate, 
nerves ascending, cymes sessile corymbiform contracted dense-flowered, calyx- 
teeth acute longer than the ovary, corolla 1-1} in., lobes obovate acute. I.

CEYLON ` not uncommon, ascending to 3000 ft. 
Leaves 33-5 in., thinly coriaceous, opaque, margins usually undulate, always 
narrowed into the short petiole; stipules with long cuspidate points. Cymes as in 
T. calycina, but calyx-teeth shorter and corolla longer with longer lobes, stigmas the
