First Rep07't on the Flora of Wyoming. 69 



As before stated the following list is based wholly up- 

 on specimens in our herbarium. Plants reported as in the 

 state are not included but appended in separate lists, 

 each under heads showing by whom and from what local- 

 ity reported. 



NOMENCLATURE AND CITATIONS. 



As the discussion of the nomenclature question is still 

 waxing warm, happily with less acerbity than before, it 

 has seemed almost a matter of indifference what view of 

 the question was taken with reference to this report. Not 

 that it is a matter of indifference to any worker in the 

 field of botany, but the question seems so far from settle- 

 ment that one may still expect almost any solution. 

 Stability is the object all have in view and those who pub- 

 lish work of any kind will use that nomenclature which 

 seems to them to offer the greatest chances for perma- 

 nency. So long as different adherents of the so-called 

 "new nomenclature" are far from agreed among them- 

 selves, as witness recent publications, there is small in- 

 ducement to abandon a fairly satisfactory system. That 

 there is room for improvement none will deny, but until 

 there is international agreement we shall hardly reach a 

 permanent, much less an ideal nomenclature. 



I greatly regret that citations in many instances are 

 quite incomplete. Meager library facilities must be my 

 excuse.
