Like all the work in Engler & Prantl, the treatment of Musci is ably 
conceived, well carried out and beautifully illustrated with much micro- 
scopic detail, by the several authors. And especially is this true of the 
part that has been assigned to Dr. V. F. Brotherus ; his is, in fact, the lions 
share of the systematic work and for this simple reason needs a somewhat 
more detailed review. 
Brotherus, then, in the first six pages pp. 277-282, brings up to date 
(i. e. 1901) the enumeration of the most important moss literature of the 
countries of the world, supplementing that of C. Muller. In a delightfully con- 
cise introduction of less than half a page (p. 282) the author defines and 
defends his position regarding the systematic place of the Cleistocarpi, 
which C. Muller and Schimper separate as a natural group from the Stego- 
carpi, but which S. O. Lindberg considers as a lower stage of development 
of the latter. He holds Lindberg’s view the more defensible here, as well 
as in the delimitation of families. In the treatment of both larger and 
smaller groups the author pays a deserved tribute to Prof. Limpricht, when 
he explicitly states that the latter’s masterly treatment of European mosses 
has served him as an example in the treatment of anatomical characters in 
exotic forms. This in part explains the excellence of the many microscopical 
drawings in the work as far as completed. Nearly five pages, pp. 283-287, 
are covered by a skilfully arranged artificial Key to the Genera of Acrocar- 
pous Mosses, including the Cleistocarpi and Stegocarpi, and this as well as 
the many keys to the species of the larger genera through the up ward of 350 
pages so far published, constitutes one of the most interesting and helpful 
and therefore most satisfactory features of this most able contribution to 
universal bryology, 
In a subsequent note after the Acrocarpi are completed the writer will 
take pleasure in reviewing more in detail the author’s treatment of this 
group. Winona, Minn. 
NOTES ON NEW OR RARE MOSSES 
A Moss New to North America. 
Dr. John W. Bailey recently collected a moss near Blackfoot, Idaho, at 
an altitude of 4,000 ft. above sea level, which from the description given in 
Limpricht’s Laubmoose I, p. 524, appears to be Pterygoneurmn cavifolium 
incanum (Bry. Germ.) Jur. Laubm. FI. p. 96. 
If my determination is right, this is an addition to our North American 
moss flora. The plant was collected in goodly quantity, and will be dis- 
tributed in Fascicle 4 of my Acrocarpi.

Anacamptodon splachnoides, Brid. 
Looking over Prof. J. Franklin Collins’ “ Notes on Mosses ” Rhodora for 
August, 1903, I find that Anacamptodon splachnoides Brid. has not been 
reported from Connecticut. In the summer of 1899 I found it at Burnside, 
Conn., growing on a living Elm tree about five feet from the ground.
