W. TTmrAT.AYA and Western Tibet ; alt. 10-13,000 ft., from Kashmir and KumaoD 

 to the Karakorum, frequent, Thomson, &e. — Distrib. Alps, Caucasus, Cabul, Central 

 Asia, Siberia. 



Stems 1-6 in., usually very numerous. Hadioal leaves 1 by ^ in., obovate, persis- 

 tent or sometimes disappearing ; cauline i by J in., narrowed at the base. Pedicels 

 j-2 in., mostly long. Sepals j-^ by ^ in., subacute or obtvise. CorolhAuhe very 

 short ; lobes ^ by J in., blue, with green nerves, fimbriate near the base. Anthers 

 somewhat large, oblong, often as long as the filaments. Capsule \ in., oblong, acute, 

 sessile. Seeds numerous, small, ellipsoid. 



2. P. Thomsoni, Clarlte ; branching from the base, cauline leaves smaE 

 elliptic, pedicels elongate, sepals J in. elliptic, corolla 5-merous lobes 5 in. naked 

 at the base. — Pleurogyne sp. 2, Herb. Ind. Or. H.f. ^ T. 



W. Tibet, alt. 15-18,000 ft. ; Thomson, Straohey. 



Cauline leaves \—\ in. Corolla-lobes at base naked or with obscure depressions. 

 Anthers large, oblong, often as large as the filaments. — Mr. Bentham doubts whether' 

 this should not be removed to Swertia, but the depressions at the base of the petals 

 are never well marked, and the habit is so exactly that of P. carinthiaca that some 

 examples are hard to distinguish from that, while others are less than 1 in., .with 

 very small flowers. 



3. P. brachyanthera, Clarke ; branching from the base, cauline leaves 

 small elliptic, pedicels elongate, corolla 4-merou3 lobes ^-^ in., anthers ovate 

 very small much shorter than the filament. 



Westeen Tibet ; Karakorum, alt. 13,000 ft., Clarke. 



Catdine leaves J-J in. Sepals ^ in., elliptic. Corolla-lobes at base slightly fimbriate, 

 — The anthers are unlike any examples of P. carinthiaca or P. Thomsoni. Kesembles ■ 

 a starved state of P. carinthiaca. 



4. P. spathulata, A. Kerner J^ov. Sp. ii. 8 ; branching from the base, 

 cauline leaves linear-oblong, pedicels elongate, sepals narrowly oblong about 

 half the length of the corolla. 



N. Kashmir; alt. 13,000 ft., Stoliczlca, &c. Lahul {A. Kerner). 



Closely allied to P. carinthiaca. Radical leaves 1^ in., linear-spathulate ; cauline 

 4 by i in. Corolla-lobes often f in., more than twice as long as the sepals. Anthers 

 large, oblong. Capsule and seeds as in P. carinthiaca, but rather larger. 



5. P. 7 minor, Benth. in Gen. PI. ii. 816 ; stem erect, cauline leaves ovate 

 or elliptic, flovfers 4-merous panicled pedicels ^-1 in., corolla f-^ in. Ophelia 

 minor, Griseb. in DC. P-odr. ix. 126 ; Wight Ic. t. 1332 : Dah. % Gibs. Bomb,
