THE JO U JIN A L OF BOTANY 
appearing with Chloris clivaricata among the grasses (p. 84) and two 
Casuarinas in Cyperaceae (p. 88). The shiny paper and small (though 
clear) type employed will, we think, somewhat militate against the 
usefulness of the volume to the school-children and “persons engaged 
in pastoral or agricultural pursuits ” for whom it has been written. 
It is doubtless on account of its provision for this special public 
that the book contains no bibliographical references, nor is there any 
indication that species are here first published, as we suspect to be 
the case; should this be so, the absence of Latin diagnoses, as the 
Rules now stand, debars the names from recognition. The author’s 
preface contains no information on this head, nor is it possible, in 
the absence of a complete acquaintance with recent Australian botani¬ 
cal literature, to ascertain which species have previously appeared 
elsewhere. Synonyms are hardly ever quoted. We are glad to note 
that no attempt has been made to provide each plant with an 
“English” name, although examples occur—“ Bromus madritensis, 
Madrid Brome.” 
Although, as has been said, there is an absence of bibliographical 
references, it is evident that the literature has been carefully examined; 
thus the substitution of llomulea parv{flora for It. Coliomnce made 
in this Journal (1914, 4b) has been duly followed, though the sub¬ 
sequent note (p. 217) in which it was shown that the name rests on 
earlier authority has been overlooked; and names published in the 
Illustrations of Australian Plants (1905) collected during Cook’s 
first voyage are taken up. 
The Orchidacece, which occupy pp. 114-154, have been under¬ 
taken by I)r. 11. S. Rogers, who occupies towards the order in Aus¬ 
tralia the position formerly filled by 11. D. Fitzgerald. Here, again, 
we suspect that a large proportion of the species to whose names 
“ Rogers ” is attached are here first published, but there is no indi¬ 
cation to that effect. The descriptions as a whole are much longer 
than those in the other orders; the figures, too, from drawings by 
M iss R. C. Fiveash, are more elaborate and show useful details. 
We shall await with interest the continuation, which we hope 
will not be long delayed, of this useful work, on the execution of 
which the author, Mr. J. M. Black, is to be congratulated; its 
cheapness is one of its most noteworthy features. We venture to 
suggest that the blank pages of the wrapper might profitably have been 
occupied by an index to the genera included in the part. 
Manual of the Trees of North America {exclusive of Mexico'). By 
Charles Sprague Sargent, Director of the Arnold Arboretum 
of Harvard University, with 783 illustrations from drawings

Edition, pp. xxvi, 910. London : Constable. £2 5s. 
This new edition of a book which since its publication in 1905 
has been the recognized authority for all who desired to obtain in a 
compact form a comprehensive account of North American trees, has 
been rendered necessary not only by the increased knowledge of the 
subject, but by the fact that the original issue has for some time 
been out of print. How great the increase of knowledge has been
