Subsequent history. DeCandolle, Prodr., 5: 265, repeated parts 
from the above quoted description, adding (in Latin): ‘ An aster 
in the garden of Paris 1818, cultivated under the erroneous name 
of A. corymbosus, seems to belong here, but has ligules a little 
longer than the involucre, not shorter." Rays longer than the 
oee seem the rule with native plants. 
Wm. Boott, a careful student of the asters, and who 
Pis about this time with a copy of Nees’ recently published 
Genera Asterearum now preserved in the library of the Gray Her- 
barium — sought to identify native plants to correspond to Nees’ 
descriptions. He came closer to it in A. Schrederi, but in A. 
E his identification proved to ide on a young subsessile 
e of A. macrophyllus, a species which, unlike A. seals si 
is hen glandular. The specimen, which is in the Torr y her- 
barium, still bears Dr. Gray's peremptory correction, M S the 
ordinary A. macrophyllus.” 
Boott’s identification failing, Torrey and Gray seem to have con- 
cluded that no native plants were to occur, and remarking that the 
species A. glomeratus was apparently an accidental state, they 
omitted the species from the Flora of North America, 1841-3, 
since which it has remained unrecognized till my republication in 
Britton and Brown’s Illustrated Flora in 1898 
I began searching for its native counterpart about the Potomac 
region in 1886 and onward, but the allied form occurring there 
which possesses glomerate heads (A. curvescens), has very different 
bracts and much larger, broader more curving leaves than indicated 
in Nees’ description ; and I could never find a representative wholly 
satisfactory for the true A. glomeratus of Bernhardi until 1896, 
when searching for Asters on the continental watershed close 
south of Lake Erie near the source of Canadaway Cr., when a 
score of fine plants suddenly looked out upon me from the grassy 
edge of bushes at the foot of a high bank of crumbling shale. 
Similar secluded ravines have often disclosed its presence since. 
Various unrecognized collections of this species by Beyrich and 
Ravenel in Georgia, by Professor C. H. Peck in several places in 
New York state, etc., had meanwhile occurred, and probably it will 
yet be found throughout the intermediate Appalachian region. 
* * * Bracts ciliate ; teeth of crenate-serrate type; heads in 
high-convex or cylindrical mass, loose ; texture coarse and thin.
