their common stations given. The following list of species 

 comprehends perhaps the larger part of our more common Ca- 

 rices, and, as the result of the investigations of a single lover of 

 plants, during a few seasons only, may have its proportion of 

 interest with others devoted to the same pursuits. The names 

 and arrangements are, in general, according to Torrey's Cy- 

 perdcece.

This list, of forty-eight forms of Carex, consists only of 

 such as I have myself found within ten miles of Boston. But 

 it may be increased by the addition of several species, for 

 which I am indebted to other investigators, and, at the best, it 

 can only be regarded as a very imperfect approximation to the 

 probable number. Including the additional forms just referred 

 to, I should estimate the number of our carices, growing in 

 the immediate neighborhood of Boston, at about fifty-six. 



Of our other cyperaceous plants, the groups comprehended 

 in the old genus Scirpus make up the greater proportion. Of 

 these there are at least fourteen species within the district 

 above mentioned, not including the very remarkable and inter- 

 esting forms at Tewksbury and Plymouth. Eleocharis Rob- 

 bins'ii Oakes, and another Elcucharis, as yet undetermined,
