var. raildii. Stems mostly tall, 3 to 5.5 dm. high; stolons more 
slender and elongated: youngest leaves often sparingly pubescent, 
very soon glabrate: heads larger, involucre 8 to 11 mm. high; the 
broader more distinctly imbricated bracts with conspicuous long white 
petaloid tips, the outer blunt, the inner acute or bluntish.—A very 
attractive plant collected by Mr. Rand in 1897, at various stations on 
Mt. Desert Island, Me.: roadside near Ripples Pond, July 3 ; roadside, 
head of Northeast Arm, Great Pond, July 3 ; near Indian Point, 
July 1 ; High Head, July 1 ; shore, Somes Harbor, July 5; pasture, 
Somesville, July 2, and at many other stations. 
■+—i— Bcisal leaves cuneate or spatulate, without distinct petioles: stolons 
slender, hardly assurgent. 
A. neglecta Greene. Stems slender, the pistillate plants 2 or 3 
dm. high; stolons slender, prostrate, usually elongated, bracteate 
throughout, except at the leafy tip : basal leaves and those at the tips 
of the stolons at first often appressed silky above, soon glabrate ; 
cauline leaves remote, small, linear, or linear-lanceolate : heads rather 
few, short-pedicelled, at first densely clustered, soon becoming 
distinctly racemose: involucre of pistillate plant 7.5 to 9 mm. high; 
bracts linear or linear-lanceolate, greenish, brown, or purplish below, 
with more or less scarious or petaloid white tips, the outer mostly 
obtuse, the inner obtuse or acute: heads of staminate plants smaller, the 
involucral bracts with broad white petaloid tips.— Pittonia, vol. 3, p. 
173, 274.—The commonest species in southern New England, grow¬ 
ing in almost every dry barren field and on sunny hillsides, and 
flowering in April or early May. The most northern specimens 
examined come from Charlotte, Yt. (C. G. Pringle), Franconia, 
N. II. (Edwin Faxon), Farmington, Me. (C. H. Ivnowlton). 
var. subcorymbosa. Taller, 3 to 4.5 dm. high; heads loosely sub- 
corymbose on elongated pedicels, the lowest sometimes 6 cm. long :
