Angeles and Orange counties. The wonderful diversity of the flora of 
California compels separate manuals for different regions of the state, if they 
are to be kept within convenient compass. No one of these regions seems to 
have been in greater need of such a manual than the one selected by the 
author, The usefulness of such a book is to be determined in the using, but 
the page is clear and attractive, the keys are well organized for convenience, 
and the specialists called on for assistance are abundantly able to give it. 
The book should justify fully the evident pains given to its preparation — 
A KEY to the genera of the native and cultivated woody plants of New 
York state, as they appear in their winter condition, has been issued recently 
from Cornell University.%° One hundred and eighty-two genera are considered, 
including such plants as Epigaea. The distinguishing characters of the 
deciduous genera are chiefly those of buds, twigs, and leaf scars. The key 
will be especially helpful in determining the cultivated trees and shrubs of 
the city parks, The authors intend later to present keys to the species of 
each genus.—C, D. Howe.
