250 Lxxviii. compositj:. (J. D. Hooker.) [Aster. 



Stems 8-18 in., many, stiff, ascending from a, woody perennial stock. Leaves 1-2^ 

 by |-f in:, green, uniform on the stem, with very obscure nerves on both surfaces. 

 Littles 12-16, J-| in., narrow. Achenes ^j in., pubescent; pappus rather longer, 

 hairs few, slender, white. — Very like A. Amellus, L., but differing in the large outer 

 invol. bracts. 



Sect. II. Invol. bracts in few series herbaceous. — Heads large, solitary, rarely 

 2-3 on a stem. 



2. A. hlmalalcus, Clarke Comp. Ind. 43 ; laxly yillous, stems leafy 

 ascending-, radical leaves persistent petioled obovate-spathulate entire or toothed, 

 eauline oblong ^amplexicaul, heads solitary, outer invol. bracts broadly lanceo- 

 late leafy recurved, ligules 40-60 very narrow, achenes silky, pappus single 

 white. Diplopappus elegans, Serb. Ind. Or. Hf. 8[ T. in part. 



SiKKiM Himalaya, alt. 13-15,000 ft., J. 1). H.; Clarke. 



A small robust species when alpine, 12-18 in. in lower localities, with a single 

 head, a very leafy involucre and numerous ligules. Leaves 1-2 in. ; petiole of radical 

 sometimes very long. Heads 1^ in. diam. Achenes ^^ in. ; pappus rather longer. 



3. A. tricephalus, Clarke Comp. Ind. 43 ; puberulons, stems erect 

 leafy, radical leaves deciduous petioled obovate-spathulate, eauline oblong ^- 

 amplexicaul, heads 1-3, outer invol. bracts numerous narrow longer than the 

 inner, ligules 40-60 very narrow. Achenes pubescent, pappus simple reddish.

SiKKiM HiMAiATA, alt. 10-14,000 ft., J. B. H. ; Clarke. 



Clarke suggests the possibility of this being » more developed form of A. hima- 

 laicus, and this I supposed it to be when I found it in Sikkim ; but besides being 

 taller, the invol. bracts are narrower, and the pappus hairs red and much stouter. 



4. A. Straclieyi, Hook. f. ; dwarf, stoloniferous, pubescent or vUIous, 

 radical leaves obovate-spathulate with few distant teeth, scapes ascending one- 

 or few-leaved, heads solitary, invol. bracts few linear-oblong membranous acu- 

 minate, ligules 30-40, achenes pubescent or silky, pappus simple reddish.

Westeen AiPiNB Himalaya; Kumaon, Wallioh; Pindari, alt. 12,000 ft., Str. ^ 

 Wint., Stewart. 



A remarkable little species, with a rambling often branching roots>tock and short 

 ascending scape or stem. Leaves 1-2 in., coarsely serrate or laciniate. Heads f in. 

 diam. ; ligules about J in. Aohenes and pappus much as in the preceding, but more 

 silky. 



6. A. KeterocIiaBta, Benth. in Gen. PI. ii. 272 ; tomentose or woolly, 

 stemless or stem erect leafy, radical leaves obovate or oblanceolate entire acute, 

 eauline 1-2 oblong ^-amplexicaul, heads solitary very large, outer invol. bracts 

 linear-lanceolate acuminate, ligules 60-60, achenes ^ in. glabrate, pappus white 

 or reddish double, outer very short paleaceous. Clarke Comp. Ind. 44. A.

Alpine Himalaya and ■Western Tibet, alt. 14-18,000 ft. — Distbib. Altai Mts. 



A variable plant (annual ?) closely resembling the European A. alpinus, but differ- 

 ing from it and from the preceding species in the double pappus. — There has been 

 great confusion in the distribution of the single-flowered Himalayan Asters and 

 Erigerons collected by Dr. Thomson and myself, and which have in various herbaria 

 been named Aster alpinus, himalaicus, and elegans, Diplopappus elegans and Erigeron 

 multiradiatu^. The true A. alpiriMs, though Siberian and Central Asiatic, is not 

 known to be Himalayan ; and I fail to recognise Clarke's " A. elegans, Hf. & T.," 

 described by him at Cklcntta as from Sikkim. I find no species having biseriate 

 pappus together with very silky achenes except A. diplostephioides.
