96 EKYTHEA. 



The form which Prof. Greene describes as A. muniia 

 Durand, Mr. Coville in the Botany of the Death Valley 

 Expedition determines rightly as A. platyceras^Jjink & Otto. 

 So this Californian species is at last settled. A. corymhosa 

 Greene, of which the type is in the herbarium of the Cali- 

 fornia Academy of Sciences, is without doubt a form of A. 

 intermedia Sweet. Mrs. Brandegee's reference of it to A. 

 plaiyceras Link &, Otto was due to the universal ignorance of 

 A. intermedia Sweet and attendant confusion. 



In Colorado, the two well marked species A intermedia 

 Sweet and A. plaiyceras Link & Otto, var. liispida Gray have 

 come under my observation. 



In California there are at least three forms, viz: A. platy- 

 ceras Link & Otto, A. platyceras var. hispida Gray and A. 

 intermedia Sweet var. corymbosa (Greene). 



Dr. Prain has done American botanists a great favor in so 

 clearly setting forth the relationships of these confused Arge- 

 mones and in giving the results of his researches in the Eu- 

 ropean libraries and herbaria in such careful detail, and it is 

 to be hoped^that the monograph of the genus ( which he leaves 

 to American botanists) may some day be done as ably^as he 

 has cleared away the obstacles and prepared the way for it.
