Dr. Watson recognized the fact that the specific name sagitta- 

 tum could not be used for two different species in the genus 

 Thelypodium, but unfortunately he gave a new specific name to the 

 older plant, and kept up the name of sagittatum for the later pub- 

 lished Pac hyp odium sagittatum Nutt. On page 26 of the King 

 Expedition Report, he says the plant was " Collected by Nuttall 

 in Southern Idaho," a statement which does not seem to be borne 

 out by the fact, for the paper in which this species is described, is

 As stated above, this is the species to which Watson should 

 have applied a new specific name, instead of giving it to the earlier 

 published species. The original locality of this species is " Plains 

 on the west side of the Rocky Mountains." I have given it the 

 specific name toruloswu, in reference to the torulose pod.
