Mr. Tuckerman, on some Plants of New England. 39 
while in P. lucens they are oval or lanceolate, and petiolate. I 
have found both species in Fresh Pond. ) 
P. Rossinsu, (Oakes.) This very curious. species is quit 
abundant in Fresh Pond, Cambridge, and will, probably, as Mr. 
Oakes has suggested, be found by no means rare in New Eng- 
land 
Carex panrcunata, (L.) Ina cold swamp between Concord 
and Lexington, on the turnpike, with C. exilis, and Eriophorum 
alpinum. ‘This is the true plant, an opinion sustained by Dr. 
Gray when he examined my specimens. ‘The evtrene regularly 
paniculate form did not occur; nor is this uniformly found in 
Europe. It seems quite possible that this state may yet be found 
at our station.

Hab. Penn Yan, New York, Dr. Sartwell. Resembling C. 
cephalophora, but quite different in the fruit. It seems to me 
more difficult to distinguish it from C. vulpina. In that species, 
and C. stipata, the fruit is ovate and scarcely margined. But in’ 
C.cephalophora it is somewhat tapering towards the base, and 
conspicuously margined. By this character, perhaps, C. cephalo- 
phora, C. Muhlenbergii, C. sparganioides, and C. rosea, may be 
separated to form a distinct group; for which the name Muhlen- 
bergianze is not inappropriate, especially as most if not all the 
Species were discovered by Muhlenberg. From the Multifloree 
of Kunth these seem to differ as much as from the Vulpine.
