A Revision of the Nomenclature oe the Nebeaska 



POLYPETALAE. 

 BY P. A. KYDBEEa.* 



Herewith I submit an attempt at a revision of the nomen- 

 clature of the reported Polypetalae of Nebraska. I say an at- 

 tempt, as I know full well that the list is not perfect. Owing to 

 the fact that my time has been limited and that the otherwise 

 very good botanical library of the University lacks some of the 

 older foreign works in which original descriptions of certain of 

 our plants are to be found, I have not been able to do the work 

 as I had wished. The original description of a species is espe- 

 cially necessary in this work, as American botanists have been in 

 the habit of citing nomina nuda in the same manner in which 

 they cite names accompanied by descriptions. Professor Greene's 

 reprint of Fraser's catalogue has saved me from doing as Pro- 

 fessor MacMillan has done in a number of cases in his Metasper- 

 mae of the Minnesota valley, namely, accepting nomina nuda.
