16 Rhodora [JANUARY 
As might have been expected of these well known bryologists the 
authors have given us a valuable contribution to the list of local floras. 
It is considerably more than a catalogue. With its succinct account 
of the general characteristics of the bryophytes and its more detailed 
descriptions of the six orders recognized (Marchantiales, Junger- 
manniales, Anthocerotales, Sphagnales, Andreaeales, Bryales), as well 
as the numerous and excellent keys to the genera and species, it might 
almost be classed as a manual were it not for the fact that specific de- 
scriptions are omitted. ‘The distribution of each species in the counties 
and towns of Connecticut is clearly indicated, also the known general 
range over the surface of the earth. 
It is a pleasure to note so few things requiring adverse criticism, and 
these of little real importance. On page 91 the key indicates Pogona- 
tum and Polytrichum as having mitrate calyptrae, an error which has 
appeared in certain other bryological publications during the last 
generation. After being favorably impressed with the abundance of 
keys to genera and species one is rather surprised suddenly to realize 
that there is no key to the orders and families. However, this is of less 
importance when one remembers that 28 of the 35 families belong to 
the Bryales, and that this order has a general key to all genera, irre- 
spective of their groupings under the families. 
Aside from Hypnaceae and Dendroidaceae the arrangement of fami- 
lies and genera follows the Engler and Prantl system rather closely 
except that Weberaceae, Buxbaumiaceae, Georgiaceae, and Polytricha- 
ceae are placed at the end of the volume, as in Warnstorf's Laubmoose. 
Several of the Engler and Prantl generic names, е. g. Apolozia, Sac- 
cogyna, Nowellia, Kantia, Stephanina, Bellincinia, are respectively 
replaced in the Connecticut flora by the generally better known names 
of Jungermannia, Geocalyx, Cephalozia, Calypogeia, Radula, and 
Porella. In this connection we are glad to note that Racomitrium and 
Elodium have their original spelling, and that Octodiceras, Ricciella, 
and Sphenolobus are raised to generic rank. 
This valuable bulletin should be in the hands of all bryologists as 
well as others who are interested in a model flora of this type, and 
there is little excuse for its not being there when the State Librarian 
at Hartford advertises it for the absurdly small sum of thirty cents. —
