PHANEROGAMIA. 



There is no complete Phanerogamic Flora of the TTnited 

 Stetes. The Gamopetalse have been completed in Gray's 

 " Synoptical Flora of North America." For the remaining 

 flowering plants we must make use of the various local Floras, 

 as foUows: 



For the Northeastern United States (i.e., north of North 

 Carolina and Tennessee, and west to the 100th meridian), 

 Gray's " Manual of Botany." 



For the Southeastern United States (i.e., south of the 

 preceding, and west to tlie Mississippi Kiver), Chapman's 

 "Flora of the Southern United States." Wood's " Class- 

 book " is intended to include all the Phanerogams of both 

 the foregoing regions. 



For the region west of the Sierra Nevada Mountains, 

 Watson's " Botany of California," or Eattan's "Popular 

 California Flora." 



For the Eocky Mountains and the Plains, Coulter's " Man- 

 ual of Eocky Mountain Botany." Strictly speaking, Coul- 

 ter's Manual is intended to cover Colorado, Wyoming, Mon- 

 tana, Western Dakota, Western Nebraska, and Western 

 Kansas, but its usefulness extends a couple of hundred 

 miles farther in every direction. 



The Great Basin of Utah and Nevada and the Arizona- - 

 Texas region have no manuals as yet. For these regions 

 Watson's " Catalogue of the Known Plants of Nevada and 

 Utah " ( U. 8. Geol Explor. of the iOth Parallel, vol. v.) and 

 Eothrock's " Catalogue of the Plants collected in Nevada, 

 Utah, Colorado, New Mexico, and Arizona" ( U. 8. Oeog. 

 Surveys West of the lOQth Meridian, vol. vi.) will render 

 good service.
