quite declined to submit to any cut and dried rules of morphology even for its 
own characters; the leaf, margins were sometimes erect, sometimes recurved; 
usually entire or nearly so, but here and there subdenticulate, and generally 
showing some signs pointing that way, as if, as Mr. Chamberlain suggests, they 
were "cutting their teeth." The apex was mostly very obtuse, but here and 
there tapering, the cell structure equally variable, often showing distinct traces 
of a border, but very frequently (on the same stem) without any; in fact the plant 
showed in all directions a callous disregard for the convenience of taxonomists. 
Pottia Heimii var. hehringiana Card. & Ther. has the same short capsule, 
bluntish leaves, and tendency to a border, but the leaves are normally toothed 
and less obtuse. P. heimioides Kindb. has the leaves short and obtuse, but the 
capsule longer and cylindric, &c. P. Heimii var. obtusifolia (R. Br.) Hag. (Syn. P. 
RyaniFhilih.) is perhaps the nearest form, but that very marked plant has broader 
and shorter leaves, with plane margins, with more abbreviated characters gen- 
erally of both gametophyte and sporophyte. On the whole it appears better 
to consider the Ata plant as a remarkable form of P. Heimii with a considerable 
approach to var. obtusifolia (R. Br.) Hag.

NOTES 
A recent issue of the Revue bryologique reports the death, in January, 192 1, of 
Sign. Egidio Corti, who was a member of the Sullivant Moss Society from 1909 
to 1916. Sign. Corti was a critical student of the Italian mosses, arid had also 
investigated those of Ecuador. We understand his herbarium is for sale. 
The same issue of the Revue mentions the death of L'abbe Faurie, well 
known for his explorations in Japan and Corea. No details are given. 
We are informed that the Zoologisch-botanische Gesellschaft of Vienna 
is prepared to sell a collection containing some 12,000 specimens of mosses, more 
than 1,000 species of European material, all well prepared specimens collected 
by such bryologists, among others, as Schimper, Wilson, Lindberg, Juratzka, 
Molendo, etc. There are also many numbers from old and rare Exisccati, e.g. 
Bryotheca Europaea. Offers should be sent directly to Dr. Hans Neumeyer, 
Secretary, at Mechelgasse 3. Wein, ni/3, Austria. 
Fascicle Nineteen oiMr. ]oh.nM.H.o\zinger's Musci Acrocarpi Boreali-Amer- 
icani, sent out May 19th 1922, appears hard on the heels of the eighteenth fas- 
cicle, which was noticed in the March, 1922, issue of The Bryologist. As will 
be seen from the subjoined list, the specimens come mainly from the West and 
South; three numbers represent European collections, which we trust may in 
time be supplemented with American material. Number 4.52, ■ Amphidium 
Mougeotii, is from the type locality ; ri'umber 473 is a portion of Ravenel 's original 
collection. If we might suggest, the completion of this important series of North 
American mosses can be very greatly aided and hastened if collectors and students 
will send to Mr. Holzinger for lists of species already issued. Such a course will
