Revisio Generum Plantarum secundum leges nomenclature inter- 
nationales cum enumeratio plantarum exoticarum. Otto Kuntze 
(Part iii., Section 1, Leipzig, London, Milan, New York and 
Paris, 1893). 
Since the publication of the first two parts of his now famous 
‘‘ Revisio,” Dr. Kuntze has traveled extensively in South America 
and made large collections, the enumeration of which will make 
the greater portion of the third part of his work. On his return 
from his journeyings in the spring of the present year he found 
the questions of botanical nomenclature opened by his first volumes 
still considerably unsettled, at least in Europe,and determined to 
add to his previous important contributions to this subject. 
The greater number of the pages at present noticed are taken 
up with the collation of everything that has been written on 
nomenclature during the last year and a half, with criticisms and 
suggestions thereon by the author, in which he naturally approves 
the remarks of those who have agreed with him, and pays his 
respects to those by whom he has been attacked. One hundred 
and twenty-four authors are cited and their writings abstracted 
nearly in full; of these, nineteen are Americans. 
Chapters follow on “Orthographical License,” in which a very 
complete list of similar but not identical generic names is pre- 
sented, and a long series of principles proposed to determine 
which should be allowed to stand and which should be rejected, 
illustrating Dr. Kuntze’s great linguistic attainments; on modifi- 
cations of the Paris Code; on “1753, die Nomenclatur der Unbe- 
wussten,” where he argues against the acceptance of the date of 
publication of the first edition of Linnaeus’ “ Species Plantarum” as 
the point of departure in nomenclature of genera and species, thus 
disagreeing with the decision of the Genoa Congress, with that of 
the North American botanists and of the editors of the “Index 
Kewensis;” on “1737, der neue Compromise,” where he indicates 
his present willingness to yield the 1735 date, in favor of 1737,and 
in this as in the preceding chapter gives a list of generic names 
which would be changed from those taken up in his previous ce
