THE CORRESPONDENCE OF SCHWEINITZ AND TORREY 145 
oxycladon Sw.—I think I was mistaken in this—& it probably 
is really salebros{um] Sprgl. 
contortum Sw.—don’t you think this differs from imponens 
as well as the one I called commutatum which is only a subspecies 
of filicinum Schwagr. 
—— adnaitum Sw. Sprengel calls molle—As I have seen neither 
besides your Specimen I may well be mistaken—but it appeared to 
me to suit adnatum very well. 
—— curvifolium Sw. is certainly not cristacastrensis as you will 
see at first sight when you come to compare the cristacastr. 
which I send you—which corresponds perfectly with numbers of 
European specimens in my collect[ion] & is one of the most dis- 
tinct Hypna in nature. 
Leskea varia Sw.—this species was so called by Muhlenberg—& 
differs materially from H. radicale—the L. sericea Sw. I believe 
was a mistake—it may be Neckera cladorrh{izans]— 
I am perfectly convinced that the Anoectanglium] filiforme is 
specifically distinct fr[om] ciliatum [—] I dont think that Bridel & 
Schwagr. ever saw it. 
I crave your pardon for the flagrant mistake I committed in 
calling your Dicranum cerviculatum—D. virens—I must have com- 
mitted it by a slip of the pen—as it is in my collection by the 
name of D. cerviculatum & evidently agrees with numerous speci- 
mens of this from Europe—while it certainly as you observe, is 
very different from D. virens. 
Your J[ungermannia] nodifolia—I think is evidently distinct from 
J. ciliaris—altho’ allied—my barbarously named J. platyphylloidea 
(by which I wanted to express its near relationship to platyphylla) 
tho’ certainly very near it—I find so regularly distinct by numerous 
marks recited in my little work that it ought to be separated. 
J. platyphylla both in Europe & here always inhabits trees & 
grows in remarkably arcuately reflected tufts,—platyphylloidea— 
on rocks clothing them often to a great extent—& but slightly 
reflected or not at all—I confess I have been very negligent in the 
composition of some of my names. How Sprengel can take what 
I have called Blasia pusilla—for J. pinguis I cannot conceive. 
It has no manner of resemblance with that—of which I have this 
year found the most beautiful specimens in full fructification with
