250 LXXVIII. COMPOSITÆ. (J. D. Hooker.) [ Aster. 
Stems 8-18 in., many, stiff, ascending from a woody perennial stock. Leaves 1-23 
by $-1 in., green, uniform on the stem, with very obscure nerves on both surfaces. 
Ligules 12-16, j-$ 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. 
Secr. II. Znvol. bracts in few series herbaceous.—Heads large, solitary, rarely 
2-3 on a stem. 
2. A. himalaicus, Clarke Comp. Ind. 43; laxly villous, stems leafy 
ascending, radical leaves persistent petioled obovate-spathulate entire or toothed, 
cauline oblong 3-amplexicaul, heads solitary, outer invol. bracts broadly lanceo- 
late leafy recurved, ligules 40-50 very narrow, achenes silky, pappus single 
white. Diplopappus elegans, Herb. Ind. Or. Hf. & T. in part. 
Bt HiMALAYA, alt. 18-15,000 ft., J. D. 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 1j in. diam. Achenes A in.; pappus rather longer. 
3. A. tricephalus, Clarke Comp. Ind. 43; puberulous, stems erect 
leafy, radical leaves deciduous petioled obovate-spathulate, eauline oblong j- 
amplexicaul, heads 1-3, outer invol. bracts numerous narrow longer than the 
inner, ligules 40-50 very narrow. Achenes pubescent, pappus simple reddish, 
Diplopappus elegans, Herb. Ind. Or. Hf. $ T. in part. 
SıkxıM Hraraya, alt. 10—14,000 ft., J. D. H: Clarke. 
Clarke suggests the possibility of this being a more developed form of A. kima- 
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. Stracheyi, Hook. f.; dwarf, stoloniferous, pubescent or villous, 
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. 
Heterocheta sp., Herb. Str. § Want. 
Western ALPINE HIMALAYA ; Kumaon, Wallich; Pindari, alt. 12,000 ft., Str. d 
Wint., Stewart, 
A remarkable little species, with a rambling often branching rootstock, and short 
ascending scape or stem. Leaves 1-2 in., coarsely serrate or laciniate. Heads 3 in. 
diam. ; ligules about } in. Achenes and pappus much as in the preceding, but more 
silky. 
5, A. Heterochewta, Benth. in Gen, Pl. ii. 272; tomentose or woolly, 
stemless or stem erect leafy, radical leaves obovate or oblanceolate entire acute, 
cauline 1-2 oblong j-amplexicaul, heads solitary very large, outer invol. bracts 
linear-lanceolate acuminate, ligules 50-60, achenes A in. glabrate, pappus white 
or reddish double, outer very short paleaceous. Clarke Comp. Ind. 44. A. 
alpinus, Thoms. in Herb. Ind. Or. Hf. $ T. Heterochæta asteroides, DC. 
Prodr, v. 282. 
ALPINE HIMALAYA and Western TinET, alt, 14-18,000 ft.—Disrrin, Altai Mts. 
A variable plant (annual ?) closely resembling the European A. alpinus, but diffor- 
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 Aséers 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 
multiradiatus, The true A. alpinus, 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 Calcutta as from Sikkim. I find no species having biseriate 
pappus together with very silky achenes except A. diplostephioides.
