Euthallophyta and Cormophyta. Passing to the detailed subdivision of the 
main groups, the descriptions of orders and families and the illustrations are 
generally very good. We note that the Protococcaceae and Hydrodictyaceae 
are placed at the bottom of the large order Siphoneae, a position that is cer- 
tainly open to question. The Charales are reduced to a suborder of the 
same group, which seems curious for so highly specialized and well defined a 
line of development. Among the fungi the Brefeldian system is followed in 
part, with much of the arrangement in Engler and Prantl; and the classifi- 
cation of the Phaeophyta and Rhodophyta is a brief outline of the latter 
work. These two groups are not given the attention they deserve.— B. M

THE THIRD FASCICLE? of the list of the genera of seed plants, according 
to the system of Engler, has just appeared. The general character of the 
work was stated in this journal in the notice of the first part. In the present 
signature 1352 genera are listed, bringing the number up to 3842, the list 
beginning ie Lychnis (Caryophyllaceae) and ending with Geoffraea (Legu- 
minosae).—J. M. C. 
F. LAMSON-SCRIBNER* has published a revised edition of the second 
part of his American grasses, the first edition having been exhausted. The 
work has been entirely rewritten, the synonymy has been revised or extended, 
and the descriptions are much fuller. The two parts now contain illustra- 
tions and descriptions of 627 species, and are invaluable to those who would 
name grasses.—J. M. C 
CHARLES V. Piper and R. KENT BEATTIES have published a manual of 
the flora within a radius of about twenty-one miles around Pullman, Wash. 
This includes some twenty-four townships in Washington and eleven in
