ALPINE HIMALAYA and WEST TIBET, rare ; Nubra, H. Strachey ; Hundes, Sir. & 



Wint. Badrinath and Chur in GARWHAL, Falconer. 



. Habit and appearance of T. elegans, but more wiry, branches of panicle longer and 

 more leafy, and segments of leaves sharper. Flowers greenish. Achenes 4-10, gla- 

 brous, broadly obovate, dorsal suture nearly straight. Probably an alpine state of T. 

 cultratum. 



3. T. cultratum, Wall. Cat. 3715; PL As. Ear. ii. 26; stem 2-4 ft., 

 leaves large, flowers greenish- white, anthers with a long point, achenes 

 short-stalked 3-ribbed on each side. T. Chelidonii /3, H. /. & T. Fl. 

 Ind. 13. 



TEMPERATE HIMALAYA, from Kashmir to Sikkim, alt. 8-12,000 ft. 



Glabrous, branched. Leaf-sheatks with small auricles; leaflets ^-J in., obovate- 

 cuneate, membranous, glabrous or slightly pubescent below, obtusely 3-lobe,d, lobes 

 mucronate, of the upper leaves acute. Panicles lax. Sepals in. Achenes glabrous, 

 4-obovate, dorsal suture straight ; style straight or hooked. 



4. T. Chelidonii, DC. Prodr. i. 11 ; stem 2-8-flowered, leaves large, 

 flowers large lilac or purple, anthers shortly mucronate, achenes long-stalked 

 membranous reticulate, style incurved. T. Chelidonii y cysticarpum, H. f. 

 & T.Fl.Lid. 14. T. cysticarpum, Watt. Cat. 3714; PL As. Rar. ii. t. 129. 



TEMPERATE HIMALAYA, alt. 8-12,000 ft. ; from Kulu to Sikkim. 



Usually much-branched. Leaflets of the lower leaves I in. diam., orbicular- 

 cordate, 3-4-crenate or lobed, glabrous and pale beneath ; floral leaflets sharply toothed. 

 Panicle with long rigid branches ; pedicels often 1 in., rigid, tips deflexed, especially in 

 fruit. Flowers 1 in. diam. Sepals elliptic, obtuse. Achenes numerous, as long as 

 their stalk. Muricated bulbils often occur in the leaf axils; monstrous states have 

 many or all the achenes enlarged and seedless. 



5. T. reniforme, Watt. Cat. 3716 ; PL As. Rar. ii. 26 ; glandular when 

 young, stem 3-6 ft., leaves large, flowers small greenish-white, anthers with 

 a long point, achenes long-stalked puberulous 3-ribbed on each side, style 

 straight. T. Chelidonii a reniforme, H. /. & T. FL Ind. 13. T. neurocar- 

 pum, Royle III. 51. 



TEMPERATE HIMALAYA, from Kulu to Sikkim, alt. 8-10,000 ft. 



Usually much branched. Leaf-sheaths expanding into adnate stipules ; principal 

 divisions with white deciduous stipellae at the base ; leaflets 1-1 in. diam., orbicular- 

 cordate, often slightly 3-lobed, pale and softly pubescent beneath, floral smaller and 

 more sharply toothed. Panicle lax, decompound. Flowers smaller than in the two 

 last, i-i in diam. Sepal* very deciduous. Achenes 6-8, as long as their stalks, 

 4-obovate, dorsal suture straight. 



6. T. pauciflorum, Royle 111. 52 ; glabrous, stem 1-2 ft., leaves sub-
