12. S. alata, Royle ms. ; cauline subsessile leaves ovate acute 5-nerved, 

 corolla lurid green-yellow near the base of each lobe one round depression.

 in DC. Prodr. ix. 127; Sot. Mag. t. 5687, fig. 12. 



TEMPERATE W. HIMALAYA, alt. 4-6000 ft. ; from Kashmir to Kumaon, common. 



Stem 4-angular, often 4-winged. Calyx-lobes |- in. and upwards. Corolla-lobe* 

 purple-veined, often shorter than the calyx ; glandular depression minutely pubescent^ 

 round the margin or glabrous, covered at the base by a slit-like gland. Closely 

 resembling S. Chirata. 



13. S. nervosa, Wall. Cat. 4383; leaves elliptic-lanceolate 3-nerved 

 narrowed at the base, sepals oblong-linear exceeding the corolla, corolla-lobes 

 greenish-yellow with one orbicular gland near the base of each lobe, stigma* 

 subsessile hemispheric. Griseb. Gentian. 317, and in DC. Prodr. ix. 125. 



TEMPERATE NEPAL and SIKKIM, alt. 6-9000 ft., common ; Wallich, J. D. H., See. 



Stem 1-3 feet, 4-lineolate or 4-winged. Leaves l by in., upper cauline sub- 

 petiolate. Panicles many-flowered ; pedicels ^-l in., very variable. Sepals f by ^ 

 in., sometimes longer. Corolla-lobes ^-^ in., ovate, acute, purple-nerved or dotted ; 

 gland large, sometimes viscous, little depressed, nearly naked ; sometimes a distinct 

 pit covered by a slit-like fold with a hairy margin. Filaments linear (in one form 

 short); anthers oblong, scarcely hastate. Capsule ^ by in., ovate. Seeds 55 in., 

 polyhedral j testa somewhat loose, glistening along the edges. 



14. S. ang-ustifolia, Ham. in Don Prodr. 127; leaves narrowly lan- 

 ceolate sub-1-nerved narrowed at the base, sepals oblong-linear often longer 

 than the corolla, corolla-lobes white or blueish oblong acute with one large 

 orbicular gland near the base. Wall. Cat. 4373, and PL As. Ear. iii. 2, t. 204.

SUBTROPICAL HIMALAYA, alt. 1-6000 ft. from the Chenab to Bhotan, common. 



Generally resembling S. nervosa, the leaves narrower. Sepals equalling the 

 corolla in Wallich's type, often ^-f in. and greatly exceeding it; sometimes considerably 

 shorter than the corolla, when the species must be distinguished from S. pulchella by 

 the larger gland. Corolla-lobes ^-^ in., usually white with blue or black dots, never 

 lurid ; the large depression usually minutely pubescent on the margin, and partly 

 closed by a scale. Stamens, capsule, and seeds nearly as in S. nervosa. 



15. S. pulchella, Ham. in Wall. Cat. 4375; leaves sessile narrowly 

 lanceolate sub-3-nerved, sepals lanceolate much shorter than the corolla, 

 corolla-lobes ovate-lanceolate with one orbicular gland near the base. Ophelia 

 pulchella, D. Don in Trans. Linn. Soc. xvii. 525 ; Griseb. Gentian. 318, and in 

 DC. Prodr. ix. 126. O. porrigens, G. Don Gen. Syst. iv. 178. O. pratensis, 

 Edgeiv. in Trans. Linn. Soc. xx. 85. 



SUBTROPICAL HIMALAYA, the Terai, alt. 500-4000 ft., from Kangra to Bhutan, very 

 common. KHASIA MTS., alt. 1-4000 ft., common. 



Hardly differing from 8. angustifolia but by the shorter sepals which are hardly 

 half as long as the corolla in Wallich's type. Corolla-lobes pale-blue with deeper- 

 blue nerves and dots, erect and connivent in young fruit ; orbicular depression 

 very near the base of the corolla, covered by a small scarcely pubescent scale or 

 naked. 



VAR. elegans ; sepals exceeding the corolla or much shorter than it (on the same 

 branch), corolla-lobes subpatent in young fruit. S. elegans, Wall. Cat, 4376, not of 

 Wight. Swertia florida, Wall. Cat. 4382. Ophelia florida, G. Don Gen. Syst. iv.
