434 COMPOSITAE (COMPOSITE FAMILY) 
Time of bloom: August to November. 
Seed-time: September to December. 
Range: Maine to Ontario to the Northwest Territory and British 
Columbia, southward to Georgia, Texas, and Arizona. 
Habit: Dry, open soil; fields, meadows, roadsides, and waste 
places. 
Stem one to six feet tall, very slender, strict, hard and woody, 
with many slender, spreading branches, pale with a close, minute 
hairiness. Leaves light green, oblong to linear, spreading, rigid, 
entire, obtuse, rough-edged, sessile or clasping at the base, hardly 
more than an inch long, those on the branches much smaller, 
being mere roughened, awl-like bracts. Heads very many, hardly 
a half-inch broad, with white rays, in densely crowded, long, rather 
one-sided, racemose clusters, so closely set along the branches as 
often to conceal them and really form “white wreaths”; involucre 
top-shaped, its bracts appressed with spreading and recurved green 
tips. Achenes hairy, with tawny pappus. 
Means of control the same as for the Smooth Aster.
