times almost hidden (as in the following species), and their brown scarious edges 

 concealed. The flowers (with the achenes) rarely exceed in. long. 



8. T. robustum, If. f. # T. ; Clarke Comp. Ind. 154; very stout, softly 

 tomentose, stem subsolitary from a stout woody stock robust angled, radical 

 leaves long-petioled 3-4 in. oblong in outline 2-pinnatisect, segments linear- 

 obovoid obtuse, cauline few, heads ^ in. diam. in branched corymbs with very 

 stout woolly and leafy branches and peduncles, invol. bracts densely woolly 

 oblong with very narrow scarious pale margins, receptacle convex, flowers 

 numerous. 



WESTERN HIMALAYA ; Kunawur, below the Werang Pass, Thomson. 



I doubt this being anything but a very large robust form of T. senecionis, with very 

 stout stem and branches of the corymbs, larger heads, and woolly bracts. Root woodv, 

 with a prostrate, branched crown. Leaves long-petioled, f-1 in. diam. Achenes un- 

 ripe, but apparently as in T. senecionis, with the corolla | in. long. 



9. T. Falconer!, Hook. f. ; rather silkily tomentose or hoary, stem 1-2 

 ft. robust grooved, radical leaves 2-4 in. linear-oblong in outline 2-pinnatisect, 

 segments linear narrow acute, heads ^ in. diam. peduncled in branched corymbs 

 with linear or divided leaves, invol. bracts densely pubescent linear-oblong 

 margins narrowly scarious pale, receptacle convex, flowers about 20. 



WESTERN TIBET (or Kashmir), Falconer ; KASHMIR, Bellew. 



A very robust tall species, differing from T. robustum in the larger size, the longer 

 leaves more oblong in outline, with slender lobes. Achenes pale, linear-oblong, rather 

 dilated upwards, pericarp loose, tip truncate and lobed, with the corolla about \ in. 

 long. In Bellew's specimen the corymb is 6 in. diam., with long stout ascending 

 branches, the lower 78 in. long ; the heads are longer peduncled, and the leaves on 

 the corymb simple, slender, undivided, and 1 in. long. In Falconer's the corymbs are 

 much smaller and denser, with divided leaves. 



10. T. long-ifolium, Wall Cat. 3231 ; laxly villous, stem single from the 

 root stout 6-18 in., radical^gaves 5-10 in. slender linear in outline 2-pinnatisect, 

 segments subfiliform, heads - in. diam. in a close woolly corymb or rounded 

 cluster (rarely solitary and 1 in. broad), invol. bracts narrowly oblong with a 

 pubescent disk and broad scarious purple margins, receptacle hemispheric, flowers 

 50-60. DC. Prodr. vi. 130, exd. syn. ; Clarke Comp. Ind. 154. 



WESTERN HIMALAYA; from Kashmir to Kumaon, alt. 10-13,500 ft. 



A verj distinct species in foliage, though offering no characters of importance in 

 the head and flowers. Hoot as thick as the thumb, woody, crowned with the shining 

 base of the old petioles. Stem stout, erect, striated, not angled. Leaves very long and 

 finely cut. Heads sometimes reduced to one, then 1 in. diam., with very many invol. 

 bracts ; flowers with the achenes, ^ in. long. Achenes narrowly obovoid, with 5 strong 

 ribs; pappus 0. The form with a large solitary head is rather an abnormal develop- 

 ment than a normal variety, and, except in the absence of ligules and presence of ' 

 the shining remains of the petioles, it resembles most closely Chrysanthemum Atkin- 

 soni. 



11. T. nanum, Clarke Comp. Ind. 155; hoary, rootstock excessively 

 stout branched, radical leaves -1 in. ovate 2-pinnatisect, segments minute short 

 acute incurved, flowering stem 3 in. sparingly leafy simple, heads capitate in. 

 diam., invol. bracts with a woolly disk and broad brown scarious margins, recep- 

 tacle convex. 



WESTERN TIBET; Nubra Valley, alt. 16.000 ft, Thomson. 



This differs from all the other Indian species in the minute incurved segments of 

 the. leaves, which are quite acute ; the heads resemble those of T. nubigemim, but the 

 habit is very different. The woody root is almost as thick as the thumb, the achenes 

 are immature.
