Field, Forest and Garden Botany, by Asa Gray, revised and ex- 
tended by L. H. Bailey. 
This once popular little manual, first published in 1869, had 
never been revised nor re-edited by its author, and, in conseqence, 
had, in time, lost much of its value and become somewhat obso- 
lete. Prof.C.R. Barnes began a much needed revision which was 
later taken up and has just been successfully carried through by 
Prof. Bailey. Considering the nature of the task it is doubtful 
whether anybody else was as well equipped for it. 
The reviser states that his first aim was to preserve, as far as 
possible, the method of the original, attempting “ nothing more 
than to bring it down to date.’ The work, however, has been 
more thorough and extensive than those words would imply ; not 
only were the nomenclature and definition corrected, but the an- 
alytical keys and grouping of species into sections have been re- 
arranged and much new matter added, so that the original of 374 
pages has been increased to 503 pages. The added matter con- 
sists of no less than 82 genera and 533 species, the total number 
of species being 3203, of which 1784 are indigenous and 1419 
extra-limital (in cultivation). To give a few examples taken at 
random: Clematis has now 17 described species instead of II in 
the original ; Magnolia, 8 species and hybrids instead of 3 ; Bras- 
sica, 8 instead of 5; Zilia, 6 instead of 3; Prunus, 29 instead of 19; 
Pyrus, 16 instead of 10; Canna, 11 instead of 5; Palms, 17 instead 
of 4, &c., and the quality has kept pace with the quantity. The 
typography is also very much improved, being even better than 
that of Gray’s Manual, and, indeed, about as perfect as one could 
desire. 
This book is intended to remain, as before, a companion to the 
Manual, and the nomenclature and definition are made to conform 
strictly with it; whatever shortcomings, therefore, the Manual is 
guilty of in these respects are shared by its companion work. A 
very welcome innovation is the citation of the authority after each 
name; this, in our day, has become a necessity in a work with any 
pretention to exactness. 
As would be expected, special attention was devoted to culti- 
vated plants, whether ornamental or useful, native or introduced ; 
in this respect the revision is remarkably complete, including even
