114 Morris : North American Plantaginaceae 



mature size, and too young to have the mature internodes devel- 

 oped. However, the bracts and the flowers are suggestive of the 

 mature characters of this species. Specimens have been examined 

 from the plateau and prairie regions west of the Mississippi River. 

 To distinguish this species from the others of the spinulose group, 

 it has seemed wise to revise the former description of P. spinulosa. 

 The others I have referred to the new species P. verticillata, 

 picta, oblonga and ignota. 



To definitely understand the differences between typical Plan- 

 tago Purshii R. & S. (= P. Lagopus Pursh, not L.; P. gnaphaloides 

 (sic) Nutt; etc.) and its forms, I have tried to ascertain the char- 

 acters of the types. I have not been able to study Roemer and 

 Schultes's type, if they had one, but they refer their name to 

 P. Lagopus Pursh (Fl. i :gg. 1814), as collected in dry situations 

 along the Missouri River. Nuttall refers his name gnaphaloides 

 to his own plants, noting "(Lagopus Pursh, a name already ap- 

 plied to a very distinct species)," collected on "high and gravelly 

 hills ; commencing to appear near the confluence of the river 

 Jauke, and the Missouri." His type has not been available to 

 me, but one of his collections in Arkansas contained specimens of 

 typical Purshii, and the specimens are in his own handwriting 

 named gnaphaloides. Concerning the station of his type from the 

 river " Jauke," there has been some discussion. 



Coulter and Rose, in their Monograph of North American 

 Umbelliferae, have referred to this locality the type of an umbel- 

 lifer and suggest with question the possible equivalence of this 

 name to Jaune, the old French name for the Yellowstone, although 

 Dr. Rose has said to me that this explanation is not very satisfac- 

 tory. It is known that Nuttall did not go much west of the 

 Mandan villages, which never have extended west of the present 



indan. Previous to Nuttall' s visit to these villages

River. The only other river, whose old name is known, at whose 

 confluence with the Missouri Nuttall did collect many species, 

 which by small error could be called "Jauke," is the present Da- 

 kota or James River, in those days known as the Jacque River. 

 Its union with the Missouri is in the midst of the country which 



Nuttall traversed.
