 Eritrichium pterocaryum Torr., Bot. Mes. Bound. 142 (1859). — In this work Torrey is for the 

 first time publishing the name, Eritrichium pterocaryum, not as originally new in this publicii- 

 tion, but new as derived from a manuscript later issued as his Phanerogamia of the Pacific Coast, 

 Wilkes Exped. 415, pi. 13 (1874), this name being first based on a collection made at Walla Walla, 

 Wash. (Pickering 4" Breckenridge), which locality may, therefore, be regarded as the type locality.
