188 LXXV. RUCIACE^!. (J. D. Hooker.) [Ixora. 



-other leaves 5-9 by 1| to 3 in., narrowed into a very short petiole - in., pale -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 5-mcrous ; bracts and bracteoles long, filiform. Calyx 

 %$ in. Corolla in. across the narrow obtuse lobes. Anthers sessile. Stigma fusi- 

 form or 2-ficl, with short arms. Fruit \~ in. long, ellipsoid or oblong, straight or 

 oblique, crowned with the slender calyx-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 Ehotan specimens (Kew Distrib. 

 2983) have calyx-teeth sometimes hardly longer than the tube.

 ceolate subacute, nerves very slender, cymes sessile or peduncled coryxnbiform 

 or brachiate, branches slender, calyx-teeth oblong-lanceolate much longer than 

 the ovary, corolla glabrous, tube very slender -f in., lobes linear-oblong obtuse, 

 mouth naked. DC. Prodr.. iv. 484; W. $ A. Prodi: 429; Wt. Ic. t. 827;

WESTERN PENINSULA, from Belgaum southwards, Berry, &c. 



An erect shrub with " ash-coloured branches and pendulous slender green branch- 

 lets with compressed joints" (Roxb.}. Leaves spreading, 5-7 by f-2 in., quite smooth 

 and rather shining on both surfaces, pale and reticulate when dry ; nerves numerous, 

 slender, often almost horizontal ; base rounded or acute; stipules short, with long 

 slender points. Cymes 2-3 in. diam., from glabrous to hoary- pubescent ; branches 

 erecto-patent ; bracts and bracteoles oblong-lanceolate, caducous. Calyx in. long, 

 glabrous, with 2 erect appressed bracteoles ; teeth linear-oblong or lanceolate. 

 Corolla white, f in. across the narrow lobes. Filaments slender. Stigma elender. 

 Fruit globose or didymous, calyx-teeth persistent. In W. & A. Prodr. is a var. ft, 

 ftmnded on Wight's n. 1341, and described as having oblong-lanceolate leaves some- 

 times pubescent beneath ; I do not find the latter character on Wight's specimens. I. 

 Wallichii of Wight's Herbarium is not the plant described under that name in the 

 Prodromus, not having leaves pubescent beneath, but a slight variety of /. lanceolaria, 

 with narrower bracts and elliptic-lanceolate leaves. 



3. X. calycina, Thw. JEnum. 155; glabrous, leaves subsessile ovate ob- 

 long or orbicular obtuse or acute, base acute rounded or cordate, nerves hori- 

 zontal, cymes subsessile coryinbiform contracted dense-flowered, calyx-teeth 

 lanceolate much longer than the ovary, corolla f in., lobes ovate acute, mouth 

 glabrous. Redd. Ic. PI. 2nd. Or. t. 97. 



CEYLON ; Central Province, ascending to 7000 ft., Macrae, Walker, &c. 



A small tree. Leaves l|-3 in., coriaceous, midrib stout, dark brown and reticu- 

 late when dry; nerves 6-8 pair, slender ; stipules cuspidate. Cymes rarely peduncled, 

 -peduncles puberulous ; flowers white tinged with rose, subsessile ; bracts and brac- 

 teoles slender. Stigma short thick with short recurved arms. Filaments short. 

 Fruit \ in., ovoid or spherical; calyx- teeth persistent. 



4. X. Thwaitesii, ITooJt. 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. 

 ^icuniinata, Thw. Enum. 165, excl. var. /3, not of Roxb. 



CEYLON ; not uncommon, ascending to 3000 ft. 



Leaves 3|-5 in., thinly coriaceous, opaque, margins usually undulate, always 

 narrowed into the short petiole ; stipules with long cuspidate points. Cymes as in 

 I. calycina, but calyx-teeth shorter and corolla longer with longer lobes, stigmas the 

 same. Corolla-throat glabrous, in which it differs from Roxburgh's R. acuminata.
