282 THE JOURNAL OF BOTANY 
relating to nomenclature, Mr. Clarke is frankly anarchist. As 
regards the Latin names employed, ‘ Sic volo, sic jubeo; stat pro 
ratione voluntas ” is his motto. He follows the London Catalogue ex- 
cept when he prefers the Index Nery. and when these authorities 
are in accord, he does not scruple to reject them both in favour of his 
personal prejudice; e.g. Ranunculus Airsins which, asain ee or 
its unromantic sound, must, we think, possess for Mr. ke some

former issue dais Fore: Bot. 1897, 148-150) and there is no need 
about it. 
Of the interest and usefulness of the book as a whole there can 
isprints are commenda ly rare—we note one on p. 74, “ Gna- 
phalium Norgevicum,” and the arrangement could only be improved 
upon by the printing in full at the head of each page the name of 
the genus under consideration, as is done in the best colonial and 
other floras: this takes no ee and adds greatly to oes con- 
venience of using the book. We note one omission—Stachys alpina, 
which was recorded in this Journal for 1897 (p. 380) and igure in 
June, 1898. o one who is interested in the history of British 
botany can afford to be without Mr. Clarke’s volume.

HE approach of the holiday season ‘Sipe it desirable at once 
to call see oe to this extremely useful Flora, which has just made 
its appearance. Those who find Gremli’s admirable Swiss Flora 
insufficient and who in sufficiently at home with German to master 
botanical precios in that lan epelens will welcome the full de- 
scriptions given e present volume; the only drawback to 
the work is its aie (nearly 2 lbs.), which the pedestrian will 
find no inconsiderable addition to his impedimenta on a blazing 
summer day. 
Every care seems to have been taken to render the work useful 
to the German student, for whom of course it is primarily intended. 
There are keys to the genera and species, as well as a detailed 
descripti each, except in the case of monotypic genera, when 
the species only is described at length. So n judge 0 
e usefulness of a book of this kind without testing it in the field, 
botany. One 0 points 
omission of rbot after the names, although these are supplied 
in the excellent index; and the manufacture for each species of a 
German synonym of the kind of which the “English names”’ in 
our own book affords abundant illustration. ‘The typography of 
the book is excellent.
