(1877), in the district wliere the original and single specimen of A. 

 Preussii was collected by Fremont. The proper stipe of the legume 

 is very short, or even almost wanting, but the base of the pod is 

 abiuptly contracted. 



Astragalus artipes. Injlati, glaber, e caudice perenni subspi- 

 tharaa?us ; stipulis basi petioli (nunc parce pilosuli) adnatis ; foliolis 

 11-17 oblongis seu ovalibus (lin. 4 longis) ; pedunculis folio breviori- 

 biis conf'ertim paucifloris ; pedicellis suberectis calyce brevioribus ; 

 dentibus calycis elongato-subulatis tubo campanulato suboequilongis ; 

 coroUii albo-purpurea ; leguinine tenuiter vesicario ovato purpureo- 

 picto (pollicari) prorsus uniloculari basi parum atteuuata cum stipite 

 gracili calycem superante articulato ! — ^Nlokiak Pass, northwest corner 

 of Arizona, in ravines, Dr. E. Palmer, 1877. A single specimen col- 

 lected of this well-marked species, which is most allied to A. ampul- 

 larius of "Watson, from the same region. The distinct articulation of 

 the pod with its stipe is peculiar, but it occurs in A. oophorics, Watson, 

 and there is some indication of such a joint in A. leucophyllus. The 

 flowers are said to be creamy white, tipped with light purple. In the 

 specimen the purple tinge predominates. 



Astragalus laxcearius. Homalohi, e caudice perenni ultra- 

 pedalis ; caulibus junciforraibus ; stipulis parvis liberis ; foliis cinereo- 

 puberulis; petiolis nunc aphyllis nunc foliolis 2-4-jugis linearibus seu 

 filiformibus sparsis instructis ; pedunculis elongatis racemoso-plurifloris ; 

 calycis dentibus tubo campanulato dimidio brevioribus ; corolla (lin. 4 

 longis) ut videtur alba, carina apice purpurusceute ; Icgnminibus re- 

 fractis lato-lanceolatis plano-compressis glaberrimis baud stipitatis (lin. 

 9-15 longis 3 latis), suturis uec incrassatis uec intrusis, valvis charta- 

 ceis ; seminibus 5-12. — Near Beaverdam on the Rio Virgeu, north- 

 west corner of Arizona, Dr. Palmer, 1877. Flowers and legumes about 

 the size of those oi A.JiUpes, but the latter strictly sessile in the calyx 

 and more acute. 



Astragalus Cusickii. /;?^a^«, fere glaber ; caulibus (ultrapedal- 

 ibus) gracilibus sparsifoliatis subflexuosis ; stipulis parvulis liberis ; 

 petiolis cum rhachi junciformibus ; foliolis dissitis parvis (lin. 2-6 

 longis, majoribus angusto-linearibus, minoribus oblongis) ; pedunculis 

 elongatis laxifloris ; pedicellis brevibus mox recurvis ; calyce late cam- 

 panulato, dentibus brevissimis fere deltoideis ; corolla ut viiletur alba 

 (semipollicari) ; leguminibus pendulis tenuiter vesicariis (ultrapolli- 

 caiibus) prorsus unilocularibus obovatis acuminulatis basi in stipitem ^ 

 calyce parum exsertum attenuatis. — Union Co., in the western part 

 of Oregon, Wm. C. Cusick, comm. by G. O. Woolson. Apparently a
