218 DESCRIPTION OF ASTER; DIVARICATI 
and lower axiles few or none at flowering time, cordate-ovate, 
rather small, 234 x 134 in., with coarse and rather remote teeth 
which are irregularly couchant ; the sinus shallow, and petioles 
slender or the upper winged. 
Upper axiles and rameals peculiar, sessile, obtuse, elliptical 
spatulate or oblong, strongly tapered toward the base: 212 x 14 
in. when elliptical, or if spatulate- -oblong narrowed to 2⁄4 X 34 in. 
Inflorescence often 6 to 10 in. across, sometimes 16 i € Heads 
very small and numerous; large ones be in. broad, 45, in. high; 
on more floriferous plants $ in. "broad, 4 fg in. high, with hundreds 
such on the plants. Rays dull white. Disks soon brown, becom- 
ing a conspicuous dark umber in many extreme plants, occasion- 
ally with some red. Bracts indefinitely green-tipped, not very 
ciliate, apt to be truncate-obtuse with a slight central point. 
Late-flowering plants of gravelly spots or crevices of rocks.

30" Catskill form, intermediate toward A. divaricatus L. 
Early-flowering high-cordate dense-topped cinereous plants with 
small close sharp teeth, and thickish leaves. Bracts all of a uniform 
somewhat triangular. Stems closely cespitose, dark prune- -color, 
much bent and sinuous, chiefly 1 ft. high.

30" Cliff-clinging form. Growing out of narrow ledges or 
crevices well up the side of cliffs, and rising almost vertically in- 
stead of divergently outward as in many plants in similar situa- 
tions, or instead of curving upward as in A. Parthianus or curving 
downward as in A. arcuatus. Inflorescence of about 6-8 well- 
separated clusters which flatten as a whole into an ovoid-oblong 
outline from the failure of the lower peduncles to elongate far, the 
axis continuing high; a direct result of situation and access of 
light; the kindred typical plants of A. Claytoni on the top of the 
same rock display a much broader-topped inflorescence. Clusters 
denser than in type, and more convex.
