 1903, but with an appendix of 53 pages devoted to addition, besi- 

 des the rewriting of a considerable number of signatures or scatte- 

 red pages. For a number of groups the Cooperation of specialists

 of the recognized species, it must be conceded that an enormous 

 amount of painstaking labor has gone into the revision as well as 

 into the original edition of this, the only manual of the flora of its 

 extensive and botanically rieh region, and in the judgment of the 

 reviewer future work is likely to increase rather than diminish the 

 number of nominal species.
