i-J in., oblong, obtuse. Seeds small, nearly as of S. paniculata. — This very abun- 

 dant plant has been OTerlooked as S. paniculata and as S. angustifoUa. 



6. S. cordata, Wall. Cat. 4378; leaves sessile ovate acute 5-3-nerved, 

 filaments linear free, style cylindric stigmas subhemispherio. Ophelia cordata, 

 Cfriseb. Gentian. 315, and in DC. Prodr. iz. 124 ; Clarke in Journ. Linn. Soo. 

 xiv. 445, not of Bon. 0. nuda, Zlotszch in Reis. Pr. Wald. Bot. 91, t. 67. 



Temperate Himalaya and Westeen Tibet, alt. 4-12,000 ft., from Kashmir and 

 the Karakorum to Bhotan ; abundant westward. Khasia Mts., alt. 3-5000 ft., very 

 common. 



Stem 8-36 in., 4-lineolate. Leaves Ij by J in., obtuse, base often cordate. Panicles 

 large, many- fld., branches ascending or patent; pedicels 0-1 J in., often fascicled, 

 unequal. Sepals g by J in., ovate-lanceolate, acute. Corolla-lobes y-^ in., elliptic 

 or oblong, acute or obtuse, white or with purplish nerves ; above the base of the lobe 

 is a large orbicular viscous yellowish spot hardly depressed, not fimbriate, traversed 

 obscurely by the central nerve, not bifid ; no pits in ithe corolla-tube. Filaments 

 linear, subhypogonous, obscurely conpate at the very base ; anthers oblong, scarcely 

 hastate. Capsule (in Wallich's example) J by i in., often hardly \ in. Seeds ~ in. 

 diam., subglobose, ornamented with long raised lines of rows of glands. — Described 

 from Wallich's Kumaon example, which is Ophelia cordata fi laxa, Grisebach 1. c. ; 

 and has large flowers and capsules ; the Khasia form is nearly the same. Some Kash- 

 mir examples have very small flowers with obtuse lobes, others have very large 

 flowers ; all have the ovate sessile leaves, the coroUa-lobee with one large spot each, 

 and the peculiarly marked seeds. Ophelia cordata, Don, is said by him to have been 

 founded on Wallich's Swertia Chirata and cordata thrown together ; the description 

 refers mainly (as to the petaU and glands) to 8. Chirata. This species, like S. pur- 

 purasoens, has a form with very short filaments and linear anthers. It also occurs 

 (in N. Kashmir) with double flowers. 



7. S. bimaculata, H. f. Sf T.; Clarke in Journ. Linn. Soc. xiv. 449 ; 

 leaves elliptic-lanceolate petioled 3-nerved, corolla-lobes marked half-way up 

 with 2 green spots, filaments linear free, stigmas sessile hemispheric. Ophelia 

 bimaeulata, Sieb. 8r Zuce. Fam. Nat. 35. So Mokou, iv. t. 55. 



Bastekn Himalaya ; Sikkim and Bhotan, alt. 5-8000 ft. ; Griffith, J. D. K, &c., 

 abundant about Daijeeling. 



8tem^2-6 ft., stout, 4-angular, corymbose upwards. Leaves 3 by l\ in., or upper 

 cauline sometimes 6^ by 2f in., glabrous, petioled or at least much narrowed at the 

 base. Flowers numerous, 4-5 merous ; pedicels -j-lj in., mostly long. Sepals y in., 

 elliptic, mostly obtuse. Corolla-lobes ^— | in., broadly elliptic, white or yellowish- 

 green, with black spots in their upper half ; the two green spots in the middle viscid, 

 scarcely depressed, no pits in the corolla-tube. Filaments attached on the corolla- 

 tube ; anthers oblong, not hastate. Capsule f by j in. Seeds ^ in., cuboid-globose, 

 smooth, obscurely reticulated. 



8. S. xnacrosperma, Clarke; leaves subsessile oblong or subovate 

 acute, corolla/-lobes with 2 small oblong glands near their base, stigmas sub- 

 sessile, seeds few large smooth. Ophelia macrosperma, Clarke in Jowrn. Linn. 

 Soc. xiv. 448.— Ophelia sp. n. 15, Serb. Ind. Or. H.f. 4- T. 



Khasia Mts., alt. 4-6000 ft., very common ; Gfriffith, H.f. §■ T., &e. 



Stem 6-48 in., quadrangular, diflfisely branched upwards. Leaves IJ by ^ in., or 

 in small plants subovate. Pedicels J-2 in., mostly long. Sepals l in., lanceolate. 

 Corolla-lobes } in., lanceolate, pale lurid blue or nearly white ; the two glands vertical, 

 parallel, hardly depressed, naked or hairy. Filaments linear, free, on the corolla- 

 tube ; anthers hastate. Capsule ^ by ^ in. Seeds ^ in., ellipsoid. — Of this also 

 double-flowered examples occur wild. The whole habit and seeds of this species 

 show it to be very closely allied to JSalenia.
