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

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

 Braehycomf. 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. Ettmlia linearifoUa 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 numberiflg of the 

 Composite.

Clarke doubts this being a native of the habitat assigned above, which is further 

 beyond the limits of this Plora ; it is, however; so likely to occur in India proper, 

 that it is best to retain it.

 heterogamous, rayed (rarely djscoid) ; ray-fl. g , 1-2-seriate, fertile ; ligulfe

 rate regions. 



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

 siepkus 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 b^ng no good distinguishing characters for the latter genus.

 corymbose ; stems leafy ; leaves sessile.

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

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