142 Rydberg : Rocky Mountain flora 



Erysimum amoenum (Greene) Rydb. 

 Chciranthus iiiva/is aiiioeniis Greene, Pittonia 3 : 137. 1896. 



Lesquerella stenophylla (A. Gray) Rydb. 

 Veskana stcnopliylla A. Gray, Bost. Jour. Nat. Hist. 6: 149. 



1850. 



This was included in L. Fendlcri by Dr. Watson, but I think 

 it well distinct. 



Euklisia crassifolia (Greene) Rydb. 

 Stre/^taiitJuis crassifolins Gycgv\q, Pittonia 3 : 227. 1897. 



Dr. Greene in Leaflets (i : 81-85. D 1904) took up Euklisia of 

 Nuttall, only changing its spelling, but he overlooked that it had 

 already been proposed as a genus in Dr. Small's Flora of the 

 Southeastern United States. About three years ago I intended to 

 publish it as a genus, making Strcptaiitluts cordatiis Nutt. the type. 

 Unfortunately my notes were never published and forgotten. Dr. 

 Small, who had seen them, took up the name in his flora, giving 

 me the credit for the same. As he published only one species, E. 

 liyaciiitJioidcs, this becomes the type. Dr. Greene took up the 

 name for a group, to which neither Dr. Small's type nor my in- 

 tended type (which I also think was Nuttall's) belong. If Strep- 

 tantJnts should be split up into as many genera as Dr. Greene sug- 

 gests, neither his species of Euklisia nor those known to Nuttall 

 would fall within Euklisia. My intention was only to divide the 

 genus into two genera, Strcptaiitlius and Ejiklisia. So limited the 

 latter genus will contain the Rocky Mountain species here given.
