This fifth edition has been carefully revised and im¬ 
proved in numerous details. The genera Hieracium *), 
Ccntaurea, Carduus, Salix and Euphrasia , in particular, 
have undergone a complete revision. The pronunciation 
of Latin names is shown.by means of an accent placed on 
the tonic syllable. In other respects the arrangement and 
nomenclature of the species have been preserved as nearly 
as possible as in former editions, since the book extending 
already to 6000 copies in the first four editions, lias served 
as a basis to several catalogues. To the present edition 
has been added a tabular view of the natural families. 
In the first part of my u Neue Beitrage ” (1880) will be 
found a method by which ligneous plants may be deter¬ 
mined by their leaves.
