104 DESCRIPTION OF ASTERS ; DIVARICATI 
moderate length, neither very short nor very long, chiefly 1 to 3 
in., usually shorter than the leaf-breadth. Teeth sharp, coarsely 
salient, nearly even, projecting outward 1 in. or more. 
Leaves of the inflorescence small, short, ovate-acute to orbic- 
ular, subentire. Inflorescence: a broad corymb, flattish, and re- 
peatedly forking, the slender peduncles and pedicels long and 
broadly divergent, several chief peduncles contiguous and with 
conspicuous divaricate axile leaves. It is to these peduncles and 
especially their axiles that the specific name is most appropriate. 
Heads about 2 in. broad, sometimes more. Rays chiefly 6 to 
9, especially 6, finear-oblong, white, at first erect and involute- 
terete, soon horizontal, minutely bidentate, toward night deflexed, 
finally often deflexed by day, at last withering brown. Disks 
yellow, changing to a dull reddish-brown. 
Bracts broad, oblong, coriaceous but thin, obtuse, truncated 
or chanfer-obtuse at the greenish erect slightly-thickened ap- 
pressed tip, highly ciliate, especially at the tip. Inner bracts 
linear, obtuse, thinner, tapering slightly, with a narrow white 
scarious margin. A few outermost bracts are sometimes broadly 
and very slightly pointed, involucre 1 in. high or less, changing 
from turbinate to somewhat narrow-bell-shaped during flowering. 
Achenes light brown, finely multistriate, glabrous, little if at all 
compressed, clavate-terete, slightly constricted at top. 
n open woodlands and thickets, in rather dry soil, 
Canada and Manitoba to Georgia and Tennessee. Sept. chiefly ; 
a few in Aug. and in Oct.; with stragglers in Nov. about the 
Potomac and the Hudson. 
Very abundant in Piedmont and hilly districts of the Middle 
States. Absent from the eastern Laurencian region? ‘ Occurs 
from the western part of Quebec to the Kawinistiquia R., west of 
L. Superior,” Macoun, 1883. Absent from wide stretches of the 
Adirondack plateau and of the White Mts.; as also from the 
coastal plain in New Jersey, and southward, to which it descends 
along the great rivers, as toward Washington along the rocky 
banks of the Potomac wherever covered with deciduous trees. 
Nearly or quite absent however from many ravines where it 
should be sought; as the Niagara gorge. Macoun remarks that 
in Canada it is much less abundant than is A. macrophyllus. 
Extends south along the Appalachians, as at
