Boltonia.'] LXXVIII. COMPOSITE. (J. D. Hooker.) 249 



I know nothing of this plant, which exists only in the Calcutta Herbarium, where 

 Clarke described it. The shape of the achenes differs altogether from that of 

 Brachycnmr. Wallich's 7134 is a plant of Finlayson's, no doubt from Siam ; it is a 

 mere scrap, 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.

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. $ , 1-2-seriate, fertile ; ligule 

 elongate, white blue or purple ; disk-fl . 9 , fertile, tubular, yellow, 5-cleft. 

 Involucre campanulate or hemispheric ; bracts few- or many-seriate, outer 

 smaller or larger ; receptacle flat or convex. Anther-bases obtuse, entire. 

 Style-arms of 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. DISTKIB. Species about 200, chiefly of N. tempe- 

 rate regions. 



Aster Amellus, L., is cultivated in Indian gardens, as is the China Aster Calli- 

 sfephus chinensts, 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. 



SECT. I. Invol. bracts in few series; outer large green obtuse. Heads 

 corymbose ; stems leafy ; leaves sessile. 



1. A. Pseud aznellus, Hook, /.; soaberulous, stems simple below slender 

 leafy, leaves sessile oblong acute or obtuse entire or toothed nerves indistinct, 

 branches of corymb slender usually with many elliptic leaves, heads 1| in. 

 diana., outermost invol. bracts oblong green 'larger than the inner.
