in a secund and sometimes crowded manner on the principal branches. Involucres mostly 

 hemispherical, or somewhat turbinate. Scales in several series : a few of the outermost ones 

 resembhng the small leaves of the branchlets ; inner ones a little ciliate, with green rhomboid 

 acute tips which are loose and somewhat spreading. Rays 15 - 25, white or pale purple ■

Old fields and barren soils ; common. August - October. This plant presents many 

 varieties in size, branching, length and breadth of leaves, etc., depending on diversities of sofl 

 and situation.

Grayish with a dense pubescence, or hairy ; stem diffusely racemose-compound ; the heads 

 very numerous and crowded, somewhat unilateral ; leaves crowded, linear, entire, not taperin.

.IT tr' rfr^'^'f orTioary from its dense pubescence, but sometimes rather 

 smooth. Stem 1 - 2 feet high, rigid, much branched and bushy ; the branches crowded with 

 small leaves Leaves mostly somewhat clasping ; the cauline ones an inch or rather more in 

 kngth and 1 - 2 hues wide, rather obtuse ; those of the branches about half an inch long 

 Heads somewhat racemose and unilateral, or (in sterile soils) terminal and nearly solitary • 

 the pedicels or branchlets covered with small leaves. Involucre about 3 lines in diameter 

 shorter thaa the disk ; the scales commonly spalulate and obtuse, whitish and appressed with 

 green spreading tips ; the outer ones broader. Rays 10 - 15, white or with a tinge of purple •

Dry sterile fields, particularly in gravelly soil ; not rare. September - November The 

 ordinary form of this species is easily recognized by its hoary appearance, bushy mucii 

 branched stem with small white flowers, and small rather obtuse crowded leaves which are 

 not narrowed at the base.
