REVIEW OF THE BRYOTKECA FENNICA OFTdR. V. F. 
BROTHERUS 
L. W. RIDDLE 
The close relationship of the moss-flora of Scandinavia, Lapland, 
and Finland to our North American flora makes the set of mosses 
which Dr. Brotherus is issuing under the title of “ Bryotheca Fen- 
nica ’’ of special importance to students of our mosses. Of the 100 
species recently issued in the first fascicle, 88 are species found in 
North America. As we should expect, many of these, such as 
Distichium capillaceum (Sw.) B. & S. Dichodontium pellucidum (L.) 
Schimp., Dicranum Blytii Schimp., Amphldium ' lapponicum (Hedw.) 
Schimp., and Zygodon viridissimus (Dicks.) R. Br., are arctic-alpine 
species. But an interesting point in distribution is illustrated by the 
fact that 13 out of the 88 occur with us only in the Rocky Mts., or on 
the Pacific Coast. Among the many interesting things included are 
a series of 12 numbers of Dicranum and 7 numbers of the poly- 
morphic group of Drepanocladus ; while the peculiar Splachnaceae 
are represented by Splachnum ampullaceum, sphaericum, and luteum, 
Tayloria Imgulata {Dissodon splachnoides of Lesquereux & James’ Man- 
ual) and Tetraplodon mnioides. 
In the excellence and abundance of the material and the form of 
the set. Dr. Brotherus establishes a high standard of merit ; all the 
more noteworthy when we take into consideration the low price 
($6.00 per fascicle) at which the set is being issued. It is under- 
stood that the second fascicle will appear during the Spring of 1911, 
and that Dr. Brotherus would be glad of a few more American sub- 
scribers. Wellesley College, Wellesley, Mass.
