We have received from W. Engelmann of Leipzig the two most 
recent instalments of the important series of quarto volumes, 
admirably produced, which he is publishing under the general title 
indicated above. 
(1) In his account of The Vegetation of New Zealand, Dr. 
Cockayne sums up not only his own observations of thirty years, 
but, as his excellent and exhaustive bibliography shows, the numerous 
contributions of recent workers, among whom Thomas Kirk, William 
Oolenso, and T. E. Cheeseman hold a prominent place. This is 
preceded by an admirable summary of the history of the botanical 
investigation of New Zealand, beginning with the landing of Banks 
and Solander in 1769 and extending to the end of 1913, at which 
period the actual writing of the book was begun. 
The work is divided into four parts, which deal respectively with 
(i.) the physical geography and climate, (ii.) the vegetation of primi¬ 
tive New Zealand, (iii.) the flora and its distribution, and (iv.) its 
history from the Jurassic period to the present time. These are 
divided and subdivided into sections and chapters : thus under ii. there 
are sections on the vegetation of the sea coast, the lowlands and lower 
hills, the high mountains and the outlying islands, with one on the 
effect of settlement upon the plant-covering of New Zealand ; to this 
last, M r. G. M. Thomson’s volume on The Naturalisation of Animals 
and Plants, reviewed at some length in this Journal last year (p. 301) 
but published too late for reference in Dr. Cockayne’s book, which 
was published in 1921, forms an important supplement. The chapters 
under Sections i.-iv. on “ the leading physiognomic plants and their 
growth-forms ” are of especial interest ; other chapters under each 
section treat of the history of the plants and of plant-formations. 
The limited space at our disposal compels us to content ourselves 
with this indication of the arrangement and scope of the work ; we 
must not, however, omit to mention the excellent index—we note with 
pleasure that there is only one !—and the useful maps and plates by 
which the volume is illustrated. 
(2) Dr. Herzog has made two trips of botanical exploration to the 
Bolivian Andes, in 1907-8 and 1911-12, during which he made 
extensive collections. The volume dealing with the plant-geography 
of this district therefore embodies the results of his own investiga¬ 
tions. The introduction contains a short sketch of the history of 
previous botanical exploration and a detailed account of Dr. Herzog’s 
routes ; also a bibliography and a list of the large number of specialists 
who have worked out Dr. Herzog’s second collection, the results of 
which have been published in the Meded. van’s Rijks Herbarium, 
Leiden. A brief description of the physical geography of Bolivia
