194 THE CORRESPONDENCE OF SCHWEINITZ AND TORREY 
or two which I shall make. The great objection to studying the 
Carices in the analytical way is the very variab!e character of 
many of the species. So that it is in many instances difficult 
to say to which of the two divisions of a series the specimen under 
examination belongs. To No. 4. 6. a considerable no. of species 
will often be referred when in fact they belong to different series, 
etc.—But I will in my next letter say more on this subject. I 
have at least 6 species to add to your Catalogue—viz. C. alba 
from mountains in Massachusetts. C. xanthophysa Wahl. (C. 
follic. B. xanth. Muhl. p. 244) (but can this be your striata?) C. 
lenticularis Mich. a species from N. England & N. Y. very much 
resembling limosa. - C. Bigelovii a new species from the White 
Hills of New Hampshire. C.——n. sp. from Cape May, given to 
me as a n. sp. by Collins!! Also a fine species from the Rocky 
Mountains & another found by Nuttall on the Arkansas, be- 
sides some doubtful ones.—These I will send you, but having no 
duplicates of several of them, I must beg to have them returned.— 
In your list at the end of the table C. saxatilis is omitted. It 
should be No. 52%. If I were in your place I would omit all the 
European species of which Pursh gives habitats except those which 
I had seen myself.—Such as C. arenaria, divulsa, leporina, remota & 
distans. Pursh evidently knew nothing of the Carices, any more 
than he did of the Grasses, & has put down many species at ran- 
dom! Michaux’s synonyms are also very obscure—Who knows 
his scirpoidea, ovata, miliaris, etc? You are aware, I presume, 
that C. Lagopus of Muhl. is the C. Fraseri of Ph. & Bot. Mag.? 
We have it here in a garden, but unfortunately I lost the op- 
portunity of either seeing it in flower this season, or of obtaining 
a specimen for my herbm. I do not know how Pursh could have 
made such a mistake as to call C. Fraseri Mapania! See what 
Nuttall says.—We intend to publish your paper [67] in the 2nd 
no. of our “Annals” as soon as it is revised. The manuscript 
you sent me I shall probably return to you with my remarks— 
but I beg you will do me the favour to let me keep it at length— 
A few days since I received some charming Nepaul Crypts from 
Hooker & in my bundle was a small package for you containing 
a copy of Greville’s Cryptogamic Flora of Scotland [28]—12 nos.. 
a beautiful work—I could not resist the temptation of taking a
