THE CORRESPONDENCE OF SCHWEINITZ AND TORREY 177 
with him. There are very few duplicates except of the little 
rarities he collected on the highest parts of the Rocky Mts. Dr. 
J. has placed the collection in the hands of ħis brother here, who 
has orders to deliver me the whole, should the Doctor not return 
in one year (he being on the point of starting for the Missouri), 
or should any accident happen to him in that time. Now as he 
says himself, there is little probability of his returning to New 
York within three years, I expect to possess this unique collection, 
when you may depend on sharing the duplicatès with one or two 
choice friends. I have already taken a dozen of the little things 
from the snowy regions of the mountains & have determined some 
of them satisfactorily. Among them are two decidedly new 
species of Androsace, Rumex digynus very small & with but two 
stamens! Adoxa moschatellina—or a n. sp. very nearly allied to 
it, &c. It is my intention to present this boquet to some of our 
societies for publication. 
I did not particularly examine the Cryptogamia in Muhlen- 
berg’s Herbm. my attention being particularly directed to the 
grasses & Carices. I believe the lichens are in a good state for 
examination—The Algae are very numerous but few of them 
are determined. I believe I mentioned to you that all (or 
nearly all) the Lichens marked n.sp. in Muhlenberg’ Catalogue 
[52] are described in Acharius’ last work—his Synop. Meth. 
Lichenum [1]. 
Your list of Jungermanniae, is very respectable but I regret 
that of those which [are] most desired by me, there are no dupli- 
cates. However of those which you have so kindly offered to me, 
I take the liberty of selecting the following which would be valu- 
able additions to my Herbarium [cites 10]. As you receive speci- 
mens of which you now have no duplicates, I beg you will re- 
member me. 
Is there more than one edition of Hedwig’s Species Musco- 
rum, by Schwagrichen [29]? Do you allude to Schwagri{chen,] 
Sp. Musc. which is only called an edition of Hedwig by the mod- 
est author? Whether it be this or not we need the book here, & I 
have persuaded our Lyceum to purchase it, as I am too poor my- 
self, provided it can be obtained for $8. If you should not be 
able to get it for this sum, I will add two dollars myself, & send you
