duncles subscaose. Collected by the writer at Yucca Ariz. 

 1884. Station now called Henning. 



Astragalus lentiginosis Dougl. var. palans {A. fialaus 

 Jones Zoe iv 37.) There will be much doubt as to the distinctness 

 of this form. Most people would call it a very good species, 

 but intermediate forms occur. The A- araneosits Sheldon is an 

 intergrading form. 



Astragalus lentiginosus Dougl. var. Fremonti (T. & G.) 

 Watson Bot. King v 66 is properly referred by Watson to A. 

 lentiginosus. 



Astragalus lentiginosus Dougl. var. Coulteri (Benth), 

 [A. Coulteri Benth. PL Hartw. 307.) cannot longer be kept apart 

 from A lentiginosus and belongs to the group of annual forms. 

 In Contributions No. vii 669 the writer wrongly referred the forms 

 with glabrous pods (A. Fremonti T. & G.) to A. Coulteri as a 

 variety, following other botanists in this. 



Astragalus aridus Gray Proc. Am. Acad, vi 223 has a 

 synonym in A albatiis Sheldon. Minn. Bot. Stud. Bull ix 128. 



Astragalus ursiiius Gray Proc. Am. Acad, xiii 367 is a 

 synomyn for A. Mokiacensis Gray 1. c. and both are wholly dis- 

 tinct from A. ensiformis Jones Cont. vii 658. 



Astragalus Bolanderi Gray Proc. Am. Acad, vii 337 has a 

 synonym in A. supervacaneus Greene Erythea i 221. 



Astragalus Pattersoni Gray var. procerus (Gray) Jones 

 Cont. vii 636 has another synonym in A. Rothrockii Sheldon 

 Minn, Bot. Stud, ix 174. 



Astragalus diphysus Gray var. albiflorus Gray Bot. Ives 10, as 

 to the type in the Gray Herbarium, is mixed with two other 

 species one being a specimen of what is probably A. Pattersoni 

 Gray but may be A procerus Gray. In the Engelmann collec- 

 tion all the specimens are white flowered forms of diphysus. See 

 my Cont. vii as to the identity of the fragment in the Natl. Her- 

 barium. The var. albiflorus should therefore be applied to the 

 white flowered form of diphysus and should be suppressed. 



Astragalus giganteus Watson Proc. Am. Acad, xvii 370 is a 

 synonym for A. Yaquianus Watson Proc. Am. Acad, xxiii 270 

 and therefore there is no need even on the Brittonian basis for 

 the synonym A Tcxcnsis Sheldon Minn. Bot. Stud, ix 65.
