Imda.~\ LXXYIII. COMPOSITE. (J. D. Hooker.) 293 



Alpine region of the SIKKIM HIMALAYA, J. D. H. 



I have only a fragment of this remarkable species, the smooth soft stem is as 

 thick as a goose-quill, smooth and shining, wings narrow membranous. Leaves, upper 

 alone seen, 3-4 by 1 in. long. Invol. bracts herbaceous, in. long, spreading in fruit; 

 receptacle hemispheric ; ligules in., deeply 3-fid. Achenes J in. long ; pappus ~ in . 



6. Z. polyg-onata, DC. Prodr. vi. 465 ; stem stout winged and leaves 

 "beneath and corymb very densely woolly, leaves sessile oblong or oblong-lan- 

 ceolate obtuse denticulate, heads \ in. diam. in small corymbs immersed in thick 

 wool, invol. bracts thick, outer oblong, inner narrow pungent, ray-fl. short 

 tubular. Clarke Comp. Ind. 119. Oonyza polygonata, Wall. Cat. 3010. 



PEGU and BIHMA, on dry hills, Wallich, Maclelland, Kurz. 



Stems 1-2 ft., simple or branched above, very robust, leafy. Leaves 3-4 by f-l 

 in., very coriaceous, glabrous or rough above, sessile but not auricled at the base. 

 Heads hemispheric; invol. bracts in., outer obtuse rigid, inner quite pungent. 

 Achenes ^ in., silky ; pappus-hairs in., white, rather flattened. 



6. I. nervosa, Wall. Cat. 2960 ; DC. Prodr. v. 471 ; perennial, pubes- 

 cent hirsute or villous and glandular, stem simple or branched erect flexuous, 

 leaves sessile or subsessile elliptic or elliptic-lanceolate acute at both ends 

 subdentate scaberulous or scabrid above, nerves subparallel with the margin, 

 heads ^-1 in. solitary or corymbose peduncled, ligules white, invol. bracts linear- 

 lanceolate acute hirsute erect or recurved, outermost foliaceous or not, achenes 

 silky. Clarke Comp. Ind. excL syn. Roxb. I. asperrima and nitida, Edgew. in

TEMPERATE HIMALAYA; alt. 4-7000 ft., from Garwhal to Bhotan. KHASIA MTS. ; 

 alt. 3-5000 ft., Griffith, &c. 



Stem 1-3 ft., strict or flexuous. Leaves 2-4 by f-1^ in., usually membranous, 

 teeth remote. Heads very variable in size, and especially in the invol. bracts, which 

 are green and either appressed or squarrose, the outermost are narrow recurved and 

 usually leafy ; ligules rather broad, shorter than the breadth of the head. Achenes 

 ^ in. ; pappus dirty- white. 



VAB. pur-purascens invol. bracts narrow linear-lanceolate finely acuminate 

 straight purple glabrescent. Khasia Mts., Lobb, Clarke. The bracts differ much from 

 the Khasian specimens gathered by Griffith, or from the Himalayan, but they are 

 always very variable in this species and its allies.

7. X. Simon sii, Clarke Comp. Ind. 121 ; hirsute with yellow glandular 

 hairs, leaves subsessile oblong acute base rounded denticulate rigid hirsute on 

 both surfaces, heads long-peduncled, invol. bracts lanceolate outer shorter 

 hirsute, ligules long white, achenes narrowly oblong silky, pappus white. 



ASSAM (Bhotan ?), Dr. Simons. BHOTAN, Nuttall. 



I have seen no specimens of this species, which its author describes as being very 

 near I. nervosa, but differing in the larger heads and leaves rounded at the base. 



8. X. obtusifolia, Kerner Nov. Sp. PL Jaeschke, 18 ; stems many from a 

 woody stock short erect rigid and leaves beneath scabrid or hairy, leaves sessile 

 oblong or ovate-oblong obtuse or acute base rounded, heads 1 or few -! in. 

 diam., inner invol. bracts linear or linear-lanceolate acute rigid pubescent outer- 

 most leafy, achenes slender silky. I. oculus Christi, var. and I. Thomsoni,

Stems 6-12 in., often rigidly flexuous, leafy to the top. Leaves 1^-2 in., rigid, 

 often scaberulous above, obscurely denticulate, nerves reticulated beneath. Heads
