248 
species and varieties are described, and that *the total number 
represented in the Yosemite National Park is considerably 
greater, since the grasses, sedges and rushes are here omitted." 
The omission of the grasses and related plants is probably 
justified since the book is planned primarily for the amateur and 
tourist, but without them botanists and foresters interested in 
the grazing problems of the Sierra Nevada will find the book 
seriously lacking. 
Turning with a more critical eye to the text we find carefully 
worked out keys to the genera and species which will add much 
to the usefulness of the book. In the descriptive part emphasis 
is placed upon the species. The generic and family descriptions 
are brief, or when represented by a single species omitted entirely. 
In the conception of generic and specific lines the authors have 
been very conservative. They recognize, for. instance, only one 
rose, which they term Rosa californica; as a matter of fact there 
are two roses in the region, neither of which, in our opinion, is 
typical К. californica. Again, Castilleia parviflora and C. 
miniata are included although students of the genus have long 
since recognized the Sierra Nevada plants as distinct from those 
northern. species. Of course these are not serious defects, 
especially in a book planned for the amateur. The plant geog- 
rapher, however, must needs be on his guard in using it for 
gathering data on plant distribution. But in many regards 
the “Yosemite Flora" is the best book that has appeared on the 
California flora since the “ Botany of California." And although 
it nominally covers only a small section of the Sierra Nevada it 
will be found very useful throughout the mountain range.

GacER's REVIEW OF PAYNE's LABORATORY MANUAL OF EXPERI-

The review of Payne’s Manual of Experimental Botany for 
high schools contributed by Dr. Gager in the June ToRREYA 
interested me considerably for two reasons: first because of
