iiig to both ends : involucre 4 or 5 lines high, little or not at all imliricated ; its bracts all of 

 nearly equal length, some looser outermost not rarely (^uite herbaceous: rays 3 or 4 lines 

 long, violet or purplish, rarely almost white. — Diet i. 300, chiefly (and partly A. paniculatus,

 Canada and N. New England. Like other l)oreal species, Howers early when cultivated in 

 lower latitudes. 



Var. villicaulis. A small and low form, with simple stem (a foot or less high) and 

 midrib of narrow loaves beucatli densely white-villous : heads few or solitaiy : rays deep 

 violet. — Northern Maine, at Fort Kent, Miss Furbish. 



c. Involucre of the middle-sized heads of firmer and more herbaceous orfoliaceous-tipped and linear 

 to spatulate bracts, imbricated in few to several series, of more or less unequal length, tlieir 

 summits from slightly to squarrose-spreading: leaves of rather Hrm texture: rays violet: com- 

 paratively late-flowering. 



A. Novi-Belgii, L. Eather low, rarely tall, glabrous and smooth, or pubescent in lines on 

 the In-anches : leaves from oblong to linear-lanceolate, entire or sparsely or obsciirely ser- 

 rate ; upjjer with sessile base partly clasping and not rarely somewhat auriculate : heads 

 mostly 4 or .5 lines high and bright blue-violet rays of equal length. — The commonest later- 

 flowered blue Aster of the Atlantic border, in low or wet grounds, truly polymorphous, both 

 in wild forms and in those of long European cultivation, many of wliich are not identified 

 with indigenous originals. — Spec. ii. 877 (truly founded on the ^L Nor<r-Be/f/i(e, etc., Herm.

 Diet., probably. A. floribundus, Willd. Spec. iii. 2048. Assume as most normal, if not the 

 original Leyden type, the common form away from influence of salt water, and with leaves not 

 thickish; these from narrowl}^ to' oblong-lanceolate, their upper surface not rarely scabrous, 

 and linear involucral bracts with narrow and acute .sj)reading or recurving upper portion. — 

 Common in wet grounds. New Brunswick and Canada to Georgia, chiefly eastward, but ex- 

 tending to Ohio and Illinois. A. eminens, var. vinjineus, Lindl. Bot. Reg. t. 1656, appears to 

 be a nearly white-rayed form. A. laxus, Torr. & Gray, Fl. ii. 134, a very narrow-leaved 

 form, and A. prwaltus (Nees.1), Torr. & Gray, 1. c, one with broader leaves. A. hmgifolius.

Var. laevigatus. Smooth and glabrous throughout or nearly so : leaves mostly ob- 

 long-lanceolate, little if at all thickened ; upper cauline disposed to be half-clasping by an 

 abrupt or obscurely auriculate base : involucral bracts in few ranks, rather short, all not far 

 from same length, loosely erect, and with comparatively short acutish herl)aceous tips; thus 

 resembling A. versicolor except that the involucral bracts are much less imbricated and little 

 unequal. — A. kevigatus, Lam. Diet. i. 306 ; Foir. Suppl. i. 498, not Willd. &c. A. mutabilis.

Var. litoreus. Stems rigid, low, or sometimes 3 or 4 feet high and then paniculatcly 

 much l)riinche(l, very leafy: leaves thickish and firm, very smooth (rarely upper face some- 

 what scabrous), oblong to lanceolate, upper partly clasping and sometimes auriculate : bracts 

 of the involucre loosely imbricated in several ranks, outer commonly spatulate, all but inner- 

 most with broadish or obtuse herbaceous and mostly thickish tips. — A. Nori-Belgii, L., as
