254 NOMENCLATOR FLOBjE DANICA. 



taining as it does, many genera which are favourites in cultivation. 

 The only improvement we can suggest is typographical. The 

 names of genera, subgenera, and species, are all alike printed in 

 small capitals ; and a substitution of thick type for the genera 

 and species would render consultation more easy.

The publication of the ■ Flora Danica ' has extended over a 

 period of more than a hundred and twenty years, from the issue of 

 its first fascicle in 1761 to the date of its last supplement in 1883. 

 The extensive changes of synonymy which have taken place during 

 that period will be understood by every one acquainted with 

 botanical literature, and will be fully realised by those among our 

 British botanists who were puzzled by the nomenclature adopted in 

 the last edition of the « London Catalogue,' and are not unnaturally 

 alarmed at finding that even this extensive revision can hardly be 

 accepted as final or complete. The first part of Prof. Lange's work 

 is devoted to an enumeration in double columns of the plants in 

 their chronological order, the names as published appearing in one 

 column and those now adopted in the other. To this list Prof. 

 Lange has added a number of interesting notes, many of them being 

 corrections of nomenclature and others bearing upon British plants, 

 and deserving the attention of those interested in synonymy. In 

 some cases these notes are of critical value, and we shall take an 

 early opportunity of extracting such for the benefit of our readers, 

 to many of whom Prof. Lange's work will not be readily accessible. 



Ihe second index is systematic — the arrangement followed, 

 however, is not that familiar to British botanists— and shows the 

 geographical distribution of each species in Denmark, Sweden, 

 JNorway, the Faroes, Iceland, and Greenland, these being the 

 countries represented in the 'Flora Danica.' An alphabetically- 

 arranged list of the species, with references to the Flora, completes 

 t lie work. It will be seen from this notice that, besides rendering 

 tlie 'Mora Danica' readily consumable, this ' Nonienclator ' con- 

 tains much information given in a compact form. It is beautifully 

 printed. r
