27. S. Thomsonl, Clarke ; lower cauline leaves long-petioled oblong or 

 elliptic scarcely connate upper often sessile, cymes forming a narrow panicle, 

 flowers 6-merous, glands near the base of the corolla-lobes obscure, seeds smooth 

 narrowly or irregularly winged. 



Westben Himaiata ; Kashmir ; Sonamurg, alt. 9250 ft., Thomson, Clarke. 



Eesembling in leaves and habit S. petiolata, but with more numerous smaller 

 flowers and capsules. Peduncles often 6 in. Sepals J by ^ in., acute. Corolla-lobes 

 ^ by g in., subobtuse ; glands 2 yellow spots very close to the base of the coroUa, 

 altogether obscure in T. Thomson's fine examples, usually naked, rarely minutely 

 hairy. Cwpaide ^-^ in. Beeds ys~^ ^'^■i globose, somewhat angular, wing very partial 

 and irregular ; testa close, smooth, microscopically reticulate (hence glistening). 



28. S. cuneata, WaU. Cat. 4380 ; cauline leaves spathulate-oblong or 

 petioled, peduncles long mostly 3-1-flowered, corolla 5-merous, glands Imear 

 vertical 2 near the edge of each coroUa^lobe, seeds ^ in. angular ellipsoid smooth 

 not winged. D. Don in Trans. lAnn. Sac. xvii. 520 ; Griseb. Oentian. 333, and 

 in DC. Prodr. ix. 133. S. Hugelii, Cfriseb. in DC. Prodr. ix. 133. 



AxpiNB Himalaya, alt. 11-14,000 ft.; from Simla to Sikkim; Wallich, Boyle, 

 J. D. H., &e. 



Stem 6-24 in., hollow, ^ in. thick. Leaves 3 by | in., usually obtuse. Pedicels 

 ^-2 in., mostly long. Sepals J-J in., narrowly oblong, obtuse acute or spathulate 

 and apiculate. CorolloAobes \-^ by \-^ in., obtuse ; the 2 glands fimbriate with hairs 

 ^ in. long or nearly naked. Stigmas of 2 sessile hemispheric plates. Capsule j in. 

 Seeds black-brown ; testa close, reticulated. 



29. S. ccBrulea, Boyle III. 278, t. 67, fig. 1 ; cauline leaves oblong sessile 

 ■or the lower spathulate, pedicels short, coroUa 5-merous, glands oblong small, 

 seeds ^ in. polyhedral smooth. D. Don in Trans. Idnn. Soe. xvii. 521 ; Cfriseb. 

 in DC. Prodr. ix. 132. 



Westekn Himalaya ; alt. 5-9000 ft., Boj/le ; Chumba, Clarke. 



Stem 6-18 in., ^ in. thick. Leaves nearly as of S. cuneata. Cymes forming a 

 linear dense panicle, peduncles short, pedicels rarely longer than the flowers. Sepals 

 ^— J in., narrowly lanceolate. Corolla-lobes | by J in., ovate, acute, blueish with green 

 nerves, glands with small oblong slightly fimbriate scales. Stigmas sessile, hemi- 

 spheric. Capsule f by J in., narrowly oblong. Seeds yellow-brown ; testa close, 

 reticulated. — Differs from 8. cuneata in its corolla and seeds, and is exeespively near 

 Pleurogyne rotata ; the difference is that in Pleurogyne the two scales near the base 

 of each corolla-lobe are subconfluent, forming a nearly continuous hairy ring near the 

 base of the corolla, without any definite depressions or viscous marks on the corolla- 

 lobe above them ; while in Swertia caerulea there are two oblong minute depressions 

 above the base of each corolla-lobe with an oblong scale fimbriated on its upper edge 

 produced above the base of each depression so as partially to cover it. 



Var. Watiii ; pedicels 1-2 in., sepals f by ^ in., corollar-lobes hardly longer than 

 the sepals, scales at their base more developed. — Pangi, alt. 13,000 ft.; Dr. Watt. — 

 This, except in the large calyx, closely resembles some forms of S.perennis (see Ejigl. 

 Bot. t. 1441), which has seeds totally unlike S.cmndea; but Dr. Watt's example 

 being in young flower is not certainly determinable.

30. S. multicaulls, Don Prodr.\27 ; leaves narrowly spathulate-oblong, 

 <!ymes very compound pedicels long, corolla 6-merou8, a small pit at the base of 

 each lobe with marginal fimbriae. Oriseb. in DC. Prodr. ix. 134; Clarice in
