New Zealand Plants and their Story, L. Cockayne,—The 
second edition (1919) of this well-printed and well-illustrated 
book, published as Manual No. 1 by the New Zealand Board of 
Science and Art, is virtually a new work. It presents a connected 
account of the vegetation of New Zealand and must form an in- 
dispensable complement to Cheeseman’s “Manual of the New 
Zealand Flora’’ for a botanist studying the vegetation of the 
progressive Dominion. There are 99 photographic reproductions 
in addition to text-figures. 
The vegetation is chiefly considered from ecological and phyto- 
geographical standpoints. The first chapter deals with the history 
of botanical exploration in New Zealand, and the only prominent 
name we miss is that of Dr. Cockayne himself. A second chapter 
forms an introduction to the ecology of the country and contains 
a clear exposition of the commoner terms used in its study and a 
suggestive classification of growth-forms. Following chapters 
deal with the flora of the sea-coast, forests, lowland, heath and 
rock vegetation, plants of inland waters, swamps and bogs and
