ASTER DIVARICATUS 119 
Rameals broadly sessile, ovate-triangular, acute, 1 14 x 34 in. 
or less, very conspicuous and numerous. = Ramulars inconspicu- 
ous, ovate to suborbicular, small and subentire, clustered closely 
together at the base of long subultimate branches 
Teeth conspicuous on all but the last, acutely salient, chiefly 
aquiline, rather close-set 
Leaf-substance firm, sometimes slightly roughish, color dull 
brownish-green ; the autumnal change to russet or to dull brown 
occurs all over the leaf or in patches. Radical leaves thin, agi 
or roundish, cordated, strongly toothed, 277 x 214 in. or les 
Bracts not truncate, chiefly narrow-lingual, pale, little nane, 
smooth-backed, the green tips slight and indefinite. Lower bracts 
broad, rounded, a very few acute, innermost bracts prolonged, 
narrow, obtusish, men attenuate. 
Heads small, 3 to i in. broad, jj in. high.  Pedicels long, 
slender, distinct, 1 in. to lin. long. Rays thickish, dull white, 
becoming dingy. Disks turning reddish-brown and soon fully brown. 
ian w, broad-branched plants of dull brownish-green aspect, 
rather late flowering and conspicuous in October ; partial to thin 
soil over gneiss, under moderate shade of high or thin trees, tend- 
ing there to form patches occupying the ground to the exclusion 
of anything else; also scattered in clefts of gneiss boulders, and 
upon sandy spots among rocks and quarries. Rootstocks pale ; 
young spring-growth deep purple, as the under side of the ovate- 
acute radicals long remains. Most typically developed on the 
Potomac banks, as to russet-changes, roundness and non-ciliation 
of bracts ; and abundance of large rameals. Intermediate in many 
respects between A. divaricatus, A. arcifolius, and A. ardens.
