Boltonia. ] Lem, COMPOSITÆ. (J. D. Hooker.) 249 | 
I know nothing of this plant, which exists only in the Caleutta Herbarium, where 
Clarke described it. The shape of the achenes differs altogether from that of 
Brachycome, Wallich’s 7134 is a plant of Finlayson's, no doubt from Siam ; it is a 
mere serap, the ray-fl. are in one row, and the achenes are truncate and glandular at 
the tip. Ethulia linearifolia is a Prome species, of which there is no specimen in 
Wallich’s Herbarium; it is probably the Prome plant marked “C, Prome" in 
Wallich's Catalogue, where the No. 98, placed under 2988, is the numbering of the 
Composite.

Perennial erect herbs.  Leavesalternate. Heads heterogamous, rayed ; ray- 
fl. Y, 1-2-seriate, ligule white; disk-fl. Y, fertile, tubular; limb elongate, 
5-cleft. Involucre hemispherie; bracts few-seriate, lanceolate, outer smaller;

Asiatic. - 
1. B. indica, Benth. Fl. Hongk. 174; scaberulous, leaves small oblong- 
lanceolate entire or subserrate, heads terminal on leafy branches small, invol. 
bracts 2--3-seriate, pappus scales minute connate below awned. Kurz in Journ.

Clarke doubts this being a native of the habitat assigned above, which is further 
beyond the limits of this Flora; it is, however, so likely to occur in India proper, 
that it is best to retain it. 
20. ASTER, Linn. 
Herbs or shrubs, Leaves alternate. Heads solitary corymbose or panicled, 
heterogamous, rayed (rarely discoid); ray-fl. Y, 1-2-seriate, fertile; ligule 
elongate, white blue or purple; disk-fl. 9, fertile, tubular, yellow, 5-cleft. 
Involuere campanulate or hemispheric; bracts few- or many-seriate, outer 
smaller or larger; receptacle flat or convex. Anther-bases obtuse, entire. 
Style-arms of Y flattened, tips lanceolate long or short. Achenes compressed, 
faces with 1-3 ribs or 0; pappus-hairs few or copious, scabrid, outer sometimes 
shorter rigid and paleaceous.—Distr1B. Species about 200, chiefly of N. tempe- 
rate regions. 
Aster Amellus, L., is cultivated in Indian gardens, as is the China Aster Calli- 
stephus chinensis, Nees (Clarke Comp. Ind. 41). There are no natural limits between 
the sections of this genus, and some of the Indian species of Erigeron may be refer- 
able to it, there being no good distinguishing characters for the latter genus. 
Secr. I, Inval. bracts in few series; outer large green obtuse.— Heads 
corymbose ; stems leafy ; leaves sessile. 
1. A. Pseudamellus, Hook. €: scaberulous, stems simple below slender 
leafy, leaves sessile oblong acute or obtuse entire cr toothed nerves indistinct, 
branches of corymb slender usually with many elliptic leaves, heads 1j in. 
diam., outermost invol. bracts oblong green larger than the inner.
