can, diifering from Aster in having a yellow, never blue 

 radius, whitish in S. bicolor. The habit agrees with the 

 upright, panicled, oblong-leaved species oi Aster, and the 

 principal generic distinction rests on the calyx-scales being 

 closely imbricated, not spreading. The ligulatej^or^^s of 

 the radius are properly fewer than in Aster, but such a 

 character must be variable. The receptacle is slightly 

 cellular in our solitary species, but I know not whether 

 that character runs through the whole genus, and accord- 

 ing to Gaertner it exists in some species of Aster.

In groves, thickets, grassy lanes, as well as on heaths, and moun- 

 tains, at every degree of elevation. 



Perennial. July — September. 



A very variable plant in magnitude, number and size of fiovoers, 

 and serratures of the leaves; nor do these varieties altogether 

 depend on situation, except that in alpine specimens the^ow;- 

 ers are larger and fewer. The root is woody, with long, stout, 

 simple fibres. Stem usually from 1 to 3 feet high, erect, va- 

 riously zigzag, never quite straight, leafy, angular, solid ; purple 

 below 3 most downy in the upper part, where it terminates in a 

 leafy cluster, either simple or compound, of bright yeUowJlow- 

 ers. Lower leaves stalked, elliptic-oblong, more or less acute, 

 very rough or harsh at the edges, which are closely serrated, 

 rarely altogether entire ; upper smaller, gradually diminishing 

 to bracteas, which are downy like the Jtou'er-stalks. Calyx-scales
