BRITTON, N. L, Manual of the flora of the Northern 

 States and Canada. X + 1080 pp. New-York (Henry 

 Hoer <& Co.) 1901. 



In this manual, which is essentially based on the Illu- 

 strated Flora of the same region by Britton and Brown, 

 the Neoamerican ideas of nomenclature are applied, and the 

 sequence of Engler and Prantl's Classification is adopted. 

 Not far from 4500 species are admitted, in contrast with about 

 3300 in Gray 's Manual for the same region. Synonyms are 

 omitted except when the names iised differ from (hose of the 

 Illustrated Flora, the figures in which work are referred to 

 under the several species. Keys are given to the orders, 

 families, genera, and species, and common names are applied 

 to all of the latter. During the two years that the work 

 has been in press, changes have been found necessary, and 

 these are embodied in an appendix of 16 pages, and the book 

 closes with a glossary of special terms, a list of abbreviations 

 of the names and authors, an index of Latin names, and an index 

 of English plant names. The following species appear in the 

 appendix as new: Paspalum australe Nash, P. Kentuckiense 

 Nash, Eatonia glabra Nash, Cyperus Bushii Britton, Arisaema 

 Stewardsonii Britton and Plantago halophila Bicknell.
