 of its tissues, especially the tap root, which is heavy in proportion 

 to the rest of the plant, as is typical for plants in saline localities, 

 Plantago piisilla Nuttall, 1818, and the less used and often 

 forgotten Plantago hybrida Barton, 18 18, applied to the same 

 species, may yet be the cause of some nomenclatorial controversy. 

 The writer has tried by every known method to determine the 



r 



priority of one of these names. • Dr. Barnhart ^ has discussed the 

 question quite fully. And Nuttall's name is here retained as prior 

 on the following ** internal evidence ":
