40 Mr. Tuckerman, on some Plant of New England. 
commonly also brown. Our plant agrees with original specimens 
of Wahlenberg’s variety, and of the C. Gebhardi of Hoppe. 
Koch adopts Persoon’s name, citing for Wahlenberg’s only the 
Flora Suecica, but this last was first published in the Monograph 
of the illustrious Swede, which appeared before the Synopsis of 
Persoon.—(7.) Mountains; White Mountains, Green Mountains, 
&c. Also in swamps, Phippsburg, Me., Nuttall; Penn Yan, 
New York, Dr. Sartwell. This differs still more from the true 
C. canescens than even the variety 6. ‘The form and important 
characters of the fruit seem however to forbid a separation of 
either. In 7. I have observed the color of the fruit to be always 
sreen. "The latter variety does not probably occur in Kurope ; 
but I think it passes into the former on our mountains. ‘That this 
species is the true C. canescens of Linnzeus, independently of 
the descriptions, is the opinion of Wahlenberg, Fries, Koch, and 
Torrey & Gray. The unanimous opinion of the great bota- 
nists of Sweden, with respect to a Linnean Swedish plant, 
would seem perhaps to be of more weight than even the Lin- 
neean herbarium ; a contrary opinion has however prevailed.

Hab. Rocky hills, near Montpelier, Vt., 1839. ‘This plant has 
the peculiar habit of inflorescence of C. trisperma, by which it 
is distinguished from the variety of C. canescens. In the fruit 
it differs very much from C. trisperma. ‘he stem in my speci- 
mens is very scabrous.
