VARIANTS OF ASTER DIVARICATUS 
s an extreme case of the variability possessed by Asters, I 
describe the 60 following forms in special detail. The first 8 or 9 
are transient states; the others may be more or less permanent 
forms, but have not yet given sufficient evidence of permanence to 
warrant their present recognition as species. Using the Arabic 
number these variants as 1*, 1%, 1*, etc., reserving the form ta, 
14, Ic, etc., for subspecies. 
* TRANSIENT STATES 
1? RosETTE state, an adaption with tufts of radicals for hold- 
ing over in unfavorable shaded conditions ; see description, supra. 
I" SPROUT-FORMS ; these tend to have more leafy inflorescence ; 
stem shorter, more reddened; lower leaves small, with subtrun- 
cate base; the next leaves sive the more conspicuous, ovate or 
narrower, rougher, shorter, and more bulky than in the type, also 
less serrate, and often sessile ; upper leaves (axiles) lanceolate —. 
Collections (in vic. N. Y., Sept. 29-Nov. 1), were seemingly due 
to either of these conditions 
a, loss or injury of the main stem ; 
4, new stimulus late in the season, after the work of the main 
stem is done; as the stimulus of new drainage, new supply of 
nutrition, or newly loosened or comminuted soil ;
