Since the publication of the last paper of this series, the writer 

 has been favored by the opportunity of studying several hundreds 

 of specimens in various herbaria, covering not only the species 

 heretofore treated but others in the different groups under the 

 genus. To this has been added much field work upon some of 

 the species in their natural surroundings. 



If we consider Decaisne's treatment of the Plantaginaceae, in 

 DeCandclle's Prodromus, 1852, as the first full and modern treat- 

 ment, we must consider Asa Gray's treatment of the American 

 species in the Synoptical Flora of North America, 1886, as the 

 first full revision of the group including the then known North 

 American species. Among the perennial plantains there has been 

 little change since 1886 except for the addition of a few new 

 species. Among the annual' plantains considerable revision has 

 been made by several authors. So much for the group of species 

 with four stamens, the flowers all perfect and the corolla remain- 

 ing open and expanded after the stage of anthesis. 



For the species with the stamens two or sometimes four, with 

 flowers mainly other than strictly perfect and the corolla mainly,

 necessary that considerable revision be made. The first group of
