30 LXXV. RUBIACE^E. (J. D. Hooker.) [Uncaria. 



veins very slender. Peduncles -1 in. Fruiting heads 3-4 in. diam. Capsules 

 -1 in., on pedicels as long or longer, crowned with a very small almost cupular 

 calyx-limb. Bornean specimens have silky corollas. 



7. U. sessilifructus, Roxb. Fl. Ind. i. 520 ; branches slender 4-angled 

 glabrous, leaves elliptic obtuse or obtusely acuminate shining above glabrous 

 and rather glaucous beneath, nerves 5 pair, peduncles axillary and in terminal 

 panicles bracteate in the middle, corolla-tubes glabrous lobes silky or glabrous, 

 capsules sessile. Wall. Cat. 6109 ; Kurz For. Fl. ii. 71. Nauclea scandens, 

 Roxb. mss. Ic. pict. No. 1218. 



Eastern Bengal, from SIKKIM and the KHASIA Mts. to CHITTAGONG, PEGU, and 

 TENASSERIM. 



Branches rather acutely angled. Leaves very uniform, pale-coloured, 4-4^ by 

 2-2 in., coriaceous, smooth on both surfaces, tip sometimes produced ; nerves often 

 with tufts of hairs in the axils, very oblique, veins obscure; petiole |- in.; stipules 

 2-partite. Peduncles 1-1 in., slender, often forming terminal panicles, puberu- 

 lous ; bracts 4, subulate, subequal. Heads 1 in. diam. ; fruiting not much larger. 

 Calyx-lobes small, rounded ; corolla-tube slender, lobes glabrous in Griffith's Khasian 

 specimens, silky in Wallich's. Capsules turgid, ^ in. long, pubescent. I follow 

 Wallich in accepting this as Roxburgh's R. sessilifructus, though the leaves are not 

 as described in the Flora Indica, 'soft underneath.' The stipules appear 2-partite, 

 but are not perfect. 



8. U. laevig'ata, Wall. Cat. 6111 ; branches 4-angled glabrous, leaves 

 elliptic-lanceolate glabrous on both surfaces shining above not glaucous beneath, 

 nerves 5-6 pair slender, stipules 2-fid, peduncles axillary and in terminal panicles 

 bracteate about the middle, bracts short obtuse, calyx obscurely toothed, corolla 

 glabrous, capsules sessile. 



TENASSERIM and PEGU, Wallich, Falconer, Kurz; KHASIA MTS., Griffith (Kew 

 Distrib. 2769). 



Very near U. sessilifructus, but the leaves are not at all glaucous beneath, the 

 bracts broad and obtuse, and the corolla perfectly glabrous. 



9. U. homomalla, Miq. Fl. Ind. Bat. ii. 343 ; branches tomentose or 

 puberulous, leaves ovate-lanceolate long acuminate opaque and puberulous 

 above especially on the nerves, shortly hairy beneath, nerves 6-8 pair, veins 

 remote, stipules 2-partite, peduncles all axillary bracteate above the middle, 

 flowers sessile, calyx-limb very short obscurely toothed, ovary minute cuneate 

 silky, corolla pubescent. U. pilosa, Wall. Cat. 6108 0., not of Roxburgh. 



EASTERN BENGAL ; Jyntea hills, Wallich. DISTRIB. Sumatra. 



Branches lower acutely 4-angled, upper nearly terete, closely finely pubescent. 

 Leaves 2i-3 by l-l^, gradually tapering to the long points, base rounded; petiole 

 slender, \ in. ; stipules each divided into 2 subulate-lanceolate recurved subpersistent 

 segments. Peduncles stout, 1 in., tapering from the base ; bracts obtuse. Heads | in. 

 diam. ; receptacle small ; corolla in. long. Capsules probably sessile. Differs 

 entirely from Roxburgh's U. pilosa in the fine pubescence, smaller size, petioled 

 leaves, and calyx-teeth. 



10. U. ovalifolia, Roxb. in Wall. Cat. under 6103 B. 0. (U. Gambler) ; 

 branches slender glabrous, leaves broadly elliptic-ovate or orbicular obtusely 

 acuminate membranous opaque concolorous and quite glabrous on both surfaces, 

 wrinkled when dry, stipules 2-fid, peduncles short slender all axillary bracteate 

 near the base, flowers pedicelled, calyx-lobes small round, corollas small uni- 

 formly pubescent, capsules very slender. ? U. ovalifolia, Roxb. Fl. Ind. i. 129.
