200 DESCRIPTION OF ASTER; DIVARICATI 
occur over a wide range, observed from L. Erie to Connecticut and 
the Potomac. But these seem to be variations in the direction of 4. 
carmesinus which still do not quite reach it, except in the Hudson 
region. Other intermediates of A. carmesinus occur in the Hudson 
region also, notably toward A. rupicola, A. listriformis, A. aucupa- 
rius and probably others. 
ariants. 25! Branch-forms bear little oval or oval-oblong 
subentire leaves gradually increased into long low-serrate acumi- 
nate upper leaves. Rameals suborbicular, well separated, fol- 
lowing abruptly upon the long upper caulines and axiles. 
Sprout-forms occur with all the leaves very small, non- 
cordate, oval and suborbicular to lanceolate. 
25* All-cordate form, all leaves or almost all, cordate to the in- 
florescence, shorter than in the type ; still acute, but nearly cordate- 
orbicular. Thin, green-stemmed, with narrow bracts, little ciliate, 
more apt to be eye HUE:

25° Broad-ray form: much larger plants, with green stem; 
heads a full inch broad, the rays broad, about 7 in. long. 
Cauline or axile leaves enlarged; disks still crimson but bracts 
greener.

25° Parchment-leaf form, sunburnt, in open gravelly places, 
leaves firm, thickened, in drying having a fine granular roughness ; 
crimson of the disks intense.

25’ Syncopated form, peculiar and rare extreme state, with 
subsessile heads in involucrate clusters, owing to syncopation of 
pedicels and development of unusually large subelliptic rameals. 
Bracts broader, rounder, paler. Crenation more appressed.

25° Green-awl form; virescent plants with small crowded 
heads, scarcely involucrate, peculiar in their greenish awl-shaped 
open-filiform erect rays ; filiform by involution, erect on account 
of crowding. Teeth often sharper, but bracts and crimson disks 
mf remain normal. In small clusters, in half-shade.
