ASTER CONCINNUS IN NEW ENGLAND. 
L. ANDREWS, 
EARLY in September, 1898, while botanizing with Mr. C. H. Bissell 
along the foot of the precipitous cliffs of Meriden Mountain in Connec- 
ticut, we found, growing with the little fern, Asplenium Trichomanes, 
in the crevices of the rocks, a peculiar form of Aster. As these rock- 
crevices are usually very dry and devoid of soil, rarely supporting 
more than a small amount of vegetation, the occurrence of these Asters 
was very noticeable. A few specimens were collected, and, after dry- 
ing, were examined, but with very unsatisfactory results. 
Later, in making up a package for the New England Botanical 
Club, one of these strange Asters was included. The following por- 
tion of a letter, dated June 9, 1900, from Mr. M. L. Fernald, 
phanerogamic curator of the club herbarium, gives the result of his 
investigation.
