RANUNCULACE^E. 



EXPLANATORY. 



Mr. Bakers' botanical exploration of the Gunnison Water- 

 shed in the summer of 1901, has already proven a remarkable 

 success, both as to the number and quality of the specimens; 

 while the wealth of new species ds even greater, I think, 

 than was obtained in other sections of southern Colorado 

 either by Mr. Baker in 1899, or by Baker, Earle and Tracy 

 in 1898. Many of the new things in those two earlier 

 collections are still unpublished; this being largely due to 

 my having undertaken to publish full lists of those collec- 

 tions, and in due taxonomic sequence. 



Pending the completion of volumes I and II of the 

 PLANTS BAKERIAN.E, I propose giving, as a first instalment 

 of volume III a somewhat miscellaneous congeries of 

 paragraphs dealing with new or otherwise interesting 

 species; in this absolving myself from the obligation more 

 fanciful than real of following any particular sequence of 

 Families. Any difficulty which this want of order may 

 seem to entail upon students of the sets, will be obviated 

 by an index to the genera treated, if not even to the species.
