ASTER CAMPTILIS 169 
Inflorescencewith axis strongly decurved, but the heads up- 
turned and small, often 24 in. broad, Y/ high. Bracts quite uni- 
form, pale with distinct p tips, sublingual or oblong-linear, 
rounded above into a slig 
ly acutish apex, kiss nd 
ciliolate, suggesting those of 
cate, and a little less rigid. 
Habitat on banks or lean- 
ing out from rocks, growing 
with other related Asters of 
the Divaricati which do not 
lean. Occasionally it is to 
be found hanging over slight 
depressions in moist flat 
ground in woods where other 
related Asters are growing 
erect. — Aug. and Sept. 
— Among species char- 
acteristically arcuate, A. 
camptilis has an oblong-acu- 
minate leaf-form with slight 
sinus; A. Parthianus ovate- 
lanceolate and more cordate, 
with rounded base in the a Aster camptilis 
principal leaves; A. arcua- Wit. 3. 
fus broad - cordate, abrupt 
and short, with large deep square sinus. In all these, the arcu- 
ate tendency seems connected with inherent weakness of stem 
as compared with rigid plants of A. divaricatus, A. ulmarius, etc., 
growing side by side.
