No descriptions of the plants are attempted in this cata- 

 logue and no new combinations are published, though a few 

 will probably be necessitated by the new rules of nomemcla- 

 ture. All the species mentioned, unless otherwise specified, are 

 pretty fully described in Dr. Small's Flora, which should be in the 

 hands of all who make any use of this paper. There is a good 

 deal of information about each species scattered about through 

 the foregoing pages, however, and to find it all the reader should 

 consult the index. 



Scattered through the catalogue at the proper places will be 

 found references to morphological and anatomical studies by 

 Kearney, W. E. Britton, Theo. Holm, and others, in which about 

 fifty of our species are discussed. These will doubtless be of 

 some service to any one who may hereafter have occasion to 

 make a more thorough study of the flora of the same or a similar 

 region. 



References are also given to published illustrations of some of 

 the rarer species, and little-known illustrations of some of the 

 commoner ones, especially those which are not included in 

 familiar illustrated works like Sargent's Silva and Britton & 

 Brown's Illustrated Flora.
