usually defined. Hence in the treatment of genera a somewhat intermediate 
course has been followed. 
In the interpretation and definition of species the work is conservative; in 
fact many of the recently proposed Rocky Mountain species have been reduced to 
synonomy. All categories subordinate to the species are treated uniformly under 
the trinomial, without further indication as to the supposed relationship to species; 
and it is only in the summary that we learn incidentally these are all regarded as 
varieties. The flora contains according to the summary given 116 families, 
649 genera, 2733 species, and 186 varieties. This is by no means an excessive 
number for such a diversified region. A “‘list of new names and combinations” 
is also appended, which totals 169. Some of these combinations seem scarcely 
justifiable; for example, ‘“‘Krigia virginica (L.) A. Nels.” This is a name taken 
up for K. amplexicaulis Nutt. apparently on the basis of absolute priority, but 
which is in direct violation of section 7, article 53, of the International Rules of 
Botanical Nomenclature. A very complete and convenient index, including 
scientific and common names, arranged similar to that of the seventh edition of 
Gray’s Manual, concludes the volume. : 
The press work is excellent, and there are comparatively few typographical 
errors. On page 529, under Erigeron ramosus, the date of publication for the 
Preliminary catalogue, etc., is given as “1788,” a mere typographical error for 
On the whole the revised edition gives a concise, reasonably complete, 
inexpensive, and in general conservative treatise on the flora of a region whic 
is always fascinating to the naturalist; and the clear-cut keys, and brief and lucid 
descriptions render the book particularly well adapted for the field identification 
of species. The botanical public is to be congratulated on having the revision of 
this well-known manual made by one whose continued activities in the field and 
extended knowledge of the Rocky Mountain flora have peculiarly fitted him for 
the work in hand.—J. M. GrEENMAN. :
