LuPiNUS CusiCKii Wats. Proc. Am. Acad. 22: 469. 1887. 



Liipimis brachypodus Piper, Bull. Torr. Club 20: 642. 

 1902. 



Through the kindness of Mr. Cusick I have been able to 

 see co-types of both these species. Although the specimen of 

 brachypodus is much smaller than that of Ciisickii^ a suspicious 

 resemblance in leaf shape and in pubescence led me to carefully 

 compare the flowers, with the result that the two were found to 

 be ideniical. 



Of the two descriptions. Piper's is by far the better. The 

 two types differ principally in size, Cusickii being a denser, more 

 branched plant, while the inflorescence of brachypodus is some- 

 what more elongated, one plant having it extended beyond the 

 leaves. I have not yet had a chance to study typical L. aj'idus, 

 and there is a possibility that both may be synonyms of that 

 species, thongh the original illustration would not so indicate.

The penciled date on the cover of my separate of Nuttall's 

 article led me to believe that his L. gracilis has priority over 

 the same name by Aghard, but in order to make no mistake I 

 wrote to Dr. J. H. Barnhart, Librarian of the New York Botani- 

 cal Garden, who kindly looked the matter up and wrote as fol-
