About 2000 new plant names having been published since the 

 first edition of this Catalogue was issued in March, 1898, the time 

 seems ripe for a second edition. The aim of the author has been to 

 make it as near complete and perfect as possible, and with this end in 

 view, more labor and expense has been put upon it than is usual in 

 a publication of this class. 



The page is printed upon one side only, giving space for the 

 insertion of new names, which are constantly being added. Larger 

 type has been used, which will be appreciated by many, and the 

 press work is of the best. The " Pluck Art Printery," where our 

 press-work is done, has the reputation of putting out nothing but the 

 finest kind of work. 



The intention was to number the genera throughout according 

 to their sequence in Engler &. Prantl's " Naturlichen Pflanzenfam- 

 ilien," as set forth by Drs. Torre and Harms, in their " Genera Siph- 

 onogamarum." The first fascicle only of this latter work had ap- 

 peared when the Catalogue was begun, the last available number in 

 it being Iris 1264. From that point on the calculations were made 

 direct from Engler & Prantl, where the number of th^ genus in the 

 family is given, but not the total number in the sequence. In some 

 way a miscount occurred, as at once became evident when fascicle 2 

 of the "Genera" arrived. The numbering was at once discontinued, 

 and all numbers after Nemastylis 1374 should be ignored, as they 

 are not correct. 



The author supposed that the universal acceptance of the change 

 from the obsolete arrangement of Bentham & Hooker to the more 

 rational one of Engler & Prantl was understood by all, but a com- 

 plaint that the position of the families was reversed in the first edi- 

 tion, seems to call for this remark. 



Instead of repeating the abbreviation var. before each varietal 

 name, the name is set further back under the species. 



The almost unanimous demand for a natural arrangement by 

 those who answered my circular, sent out early in the year, led to the 

 abandonment of the alphabetical arrangement of the first edition, and 



the adoption throughout of the Engler & Prantl sequence for families
