The first edition of the Check-list of North American Plants, pub- 

 lished in 1887, was soon exhausted. A steady demand for the list has 

 encouraged the publisher to issue another, retaining the large type and 

 the alphabetical arrangement of genera, species and varieties, and num- 

 bering the species and varieties. 



For the benefit of those who arrange their herbariums according to 

 Durand's Index Generum Phanerogamorum, the numbers of that work 

 are given with the generic names, both in the body of the list and index. 



I am indebted to the following specialists for lists of the species in 

 the genera and orders named: 



Epilobium, Prof. William Trelease. {E. Oreganum and E. exaltatum 

 should have been omitted by the printer or marked as probable 

 hybrids. 



Euphorbia. Dr. C. F. Millspaugh. 



Salix, M. S. Bebb. 



Carex, Prof. L. H. Bailey. 



Graminece, Dr. Geobge Vasey. 



Filices and Ophioglossaceoe, George E. Davenport. 

 In the remainder of the list the publisher has had the kind assistance and 

 advice of Dr. Sereno Watson, and the nomenclature of the revised edition 

 of Gray's Manual has been followed. 



This Check-list is published in four styles, differing only in paper 

 and binding, as follows: 



Style A. — Herbarium list, heavy paper, bound in cloth Price $1.50
