ALPINE HIMALAYA ; from Kumaon, alt. 10-12,000 ft., to Sikkim, alt. 14-16,000 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. 
braets have coloured margins and herbaceous disks. Flowers, including the achenes, 
about d in. long.— Clarke's var. bracteata of T. fruticulosum is only the weak culti- 
vated state of this plant grown from Sikkim seeds.

tomentose, stems very many 1—4 in. crowded on a stout stock leafy upwards, 
leaves j in. crowded palmately pinnatisect, segments short linear obtuse, heads 
4-4 in. diam. capitate or corymbose, invol. bracts orbicular pubescent with broad

5-ribbed with a minute terminal cup. 
Western Tipet; 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, A 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

Western Ter: 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, 45 in. long. 
** Leaves radical and cauline; stems many from the root, elongating and 
lowering, the rest short and flowerless, 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 1-1 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. J. c. 130. 
Western Hiwaraya; Lahul, Kunawur, and Garwhal, alt. 11-14,000 ft, Royle, 
Jacquemont, &c. 
Very variable, 4-10 in. high. In Jacquemont'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 euneate, rather compressed, angled, with rounded shoulders and no trace 
of a terminal eupule (as in 7. nubigenum); pericarp lax. I find no difference whatever 
between some of Jacquemont's specimens of T. senecionis, so named by Gay, and 
Royle's of tomentosum. The heads vary in woolliness, the invol. bracts being some-
