THE CORRESPONDENCE OF SCHWEINITZ AND TORREY 171 
collection of foreign Jungermanniae embraces the following species 
[lists 49]. 
I know not how I can get along without Weber’s work [93]. 
What is the price of it—Are there plates? I sent for a copy many 
months ago, but it has not yet come. Concerning several of 
your determinations of my Jungermans. I would make a remark 
or two—No. 321 you have named J. tridenticulata. Will you 
have the goodness to look at the specimen again. Perhaps I 
put up by mistake a spm. of J. trilobata. My specimens agree 
with Hooker’s plate very well, except the loculi are more numerous 
in the former. No. 366 “ Targionia hypophylla.’’ In the paper 
from which I took your specm. there appear to be two species. 
One of them (large & green) seems to be the Jung. epiphylla, the 
-other (small & red) is very near J. sinuata but still not exactly 
that. I could not find on it anything like fructification. 
No. 325. “J. curvifolia.” Thisseems to be Hooker’s plant, & 
agrees very well with my European specimens, but I think it 
different from one that you sent me as J. curvifolia. 
No. 322. “J. capillaris.” Is this the J. trichophylla of Hooker & 
others? It looks much like Hooker's pl. 7. 
No. 281. “J. nova.” This I have described as a new species, but 
I have some suspicion that Hooker has it. 
No 269. “J. viticulosa,’’ not so according to Hooker, as there are 
stipules in that plant, while they are absolutely wanting in mine. 
I have a little suspicion that it is J. asplenioides notwithstanding 
the leaves are entire. Hooker says the leaves are occasionally 
entire. I know my specimens are much smaller than the European 
J. asplenioides. l 
“JT. sertularoides.’’ The Linnaean plant is probably J. tricho- 
phylla & J. sertularoides is put as a synonym of that species by 
Hooker but the American plant is totally distinct. Do you be- 
lieve the J. laciniosa is very distinct from J. sertularoides? 
I must here close for want of room. Do let me hear from you 
soon. I hada glimpse of Mr. Halsey a day or two ago when I was 
much engaged. He had something to communicate from you 
which I shall go & hear tomorrow. I returned the other day from 
Philadelphia, where I spent a fortnight very agreeably with the de-
