many from tbe woody root elongate densely leafy upwards, leaves |- in. 2-3-

 in. diam., invol. bracts broadly oblong disk herbaceous woolly margins broad 

 scarious purple-brown, receptacle hemispheric, achenes ovoid-oblong brown 6- 

 ribbed tip rounded. Clarke Conip. Ind. 153. T. fruticulosum, var. bracteata,

ALPINE HIMALAYA; from Knmaon, alt. 10-12,000 ft., to Sikkim, alt. H-16,000 ft. 



Very closely allied to T. fruticulosum, but the root is less woody, the stems fewer 

 and more robust, the leaves more dissected, the heads rather larger, and the invol. 

 bracts have coloured margins and herbaceous disks. Flmvers, including the achenes, 

 about j^ in. long. Clarke's var. bract eata of T. fruticulosum is only the weak culti- 

 vated state of this plant grown from Sikkim seeds. 



5. T. tibeticum, Hook. f. $ Thorns.', Clarke Comp. Ind. 154; dwarf, 

 tomentose, stems very many 1-4 in. crowded on a stout stock leafy upwards, 

 leaves in. crowded palmately pinnatisect, segments short linear obtuse, heads 

 - in. diam. capitate or corymbose, invol. bracts orbicular pubescent with broad 

 coloured or pale scarious margins, receptacle convex or hemispheric, achenes 

 5-ribbed with a minute terminal cup. 



WESTERN TIBET; Parang and Lanak passes, alt. 15-17,000 ft, Thomson. 



Very near to T. nubigenum, and perhaps a dry country form of that plant ; but the 

 habit is different, the heads often much larger, and the receptacle never conical ; the 

 corollas seem to be always glandular, and the whole plant is probably strongly scented 

 when fresh. Flowers, including the achenes, ~ in. long. Specimens collected by 

 Thomson in the Parang valley have solitary heads in. diam. 



6. T. tenuifolium, Jacquem. in DC. Prodr. vi. 129; dwarf, silkily 

 tomentose, stems many short 2-4 in. densely leafy, leaves 2-pinnatisect, segments 

 linear obtuse, heads - in. corymbose, invol. bracts linear-oblong hoary margins 

 scarious brown, receptacle convex, achenes obovoid acutely angled. Artemisia 

 tenuiflora, Jacquem. Cat. 2053 ; Bess. Suppl ad Tent. Abrot. 62. 



WESTERN TIBET; Keyrie Pass, Jacquemont; Kumaon, alt. 14.000 ft., Thomson. 



Very near indeed to T. tibeticum, and probably a variety of that plant, differing 

 chiefly in the narrow lobes of the more silkily pubescent foliage. Flowers, including 

 the achenes, in. long. 



** Leaves radical and cauline ; stems many from the root, elongating and 

 jloivering, the rest short and Jloiverless, or stem subsolitary with both radical and 

 cauline leaves. 



7. T. senecionis, Gay in DC. Prodr. vi. 129; tomentose or woolly, 

 stems few or many stout long or short from a stout woody root, radical leaves 

 petioled 1-3 in. palmately pinnatisect, segments short or long linear obtuse, 

 flowering stems 3-10 in. distantly leafy, heads \-\ in. diam. capitate or in woolly 

 corymbs, invol. bracts broadly ovate with a woolly disk and broad scarious 

 brown margins, receptacle convex or hemispheric, achenes obovoid tip rounded 

 without a cupula. T. tomentosum, DC. I. c. 130. 



WESTEKN HIMALAYA; Lahul, Kuoawur, and Garwhal, alt. 11-14.000 ft., Royh, 

 Jacquemont, &c. 



Very variable, 4-10 in. high. In Jaoquemont's specimen the leaves are 3 in. long 

 and the flowering stem 8 in., but at great elevations the plant becomes dwarf and only 

 3-5 in. high. I have seen no quite ripe achenes, but the ripest appear to be between 

 obovoid and cuneate, rather compressed, angled, with rounded shoulders and no trace 

 of a terminal cupule (as in T. nubigenum) ; pericarp lax. I find no difference whatever 

 between some of Jacquemont's specimens of T. senecionis, so named by Gay, and 

 Koyle's of tomentosum. The heads vary in woolliness, the invol. bracts being some-
