GENERAL STATISTICS OF THE CATALOG, 

 AND COMPARISON WITH DUDLEY'S FLORA 



Xo attempt is here made to compare the number of plants treated in this catalog 

 with those listed in catalogs of other regions, for in each case the number depends 

 as much upon the thoroughness of exploration and the segregation of species as 

 upon the actual richness of the flora. A few statistics in reference to the present work, 

 however, as compared with Dudley's Flora, are of interest. 49

Dudley's list did not include the vascular cryptogams, of which there are now 

 listed 60 species and varieties. The present flora is, then, larger than Dudley's list, 

 in number of seed plants, by 310 species and varieties. The following tables 

 present this comparison somewhat in detail.

48 Where a species is represented in this flora by a variety only, such a variety is counted as a 

 species, not as a variety, in the following tables. Species and varieties in brackets are not counted. 



50 To facilitate comparison, the number from Dudley excludes the hybrids and forms to which a 

 number was given by him, and includes plants designated by him with an already-used number plus 

 a distinguishing letter.
