one, and includes 4885 differentiated species or minor forms per- 

 taining to 1001 admitted genera (of which 706, pertaining to 180 

 genera, are introduced). By groups the native forms are: 



Pteridophyta .... 31 genera, 176 species &c. 

 Gyrnnospermae ... 10 „ 27 „ „ 



Monocotyledoneae . . 184 „ 1229 „ „ 



Dicotyledoneae . . . 596 „ 2747 „ „ 



In addition to an analytical key to the families, keys areprovided 

 for generic determination, and although the familiär synoptical 

 treatment of the latter is followed, their species are frequently also 

 differentiated by keys, which show evidence of unusually careful 

 preparation. A glossary of technical terms foUows the descriptive part 

 of the book: and a füll index of common and Latin names, including 

 Synonyms and occupying over forty pages of form columns each, 

 forms by no means the least useful feature of a book which worthily 

 maintains the Standard of its excellent predecessors. Trelease.
