 PI. Fendl. 1. c. Glabellus vel pube appressa puberulus, erectus, ultra- 

 pedalis ; foliolis oblongis seu lineari-oblongis ; racemis longe peduncu- 

 latis laxifloris ; corolla purpurea (lin. 4 louga) ; legumine ovali inflate 

 recto apiculato minute puberulo, stipite brevissirao. — New Mexico, in

87. A. Hallii, sp. nov. {A. Phacce dehili alF., Gray, Enum. coll. 

 Parry, Hall, & Harbour, 1. c. no. 121.) Subcinereo-pubescens, glabra- 

 tus ; caulibus pedalibus adsurgentibus ; stipulis subulatis ; foliolis 9—12- 

 jugis angusto-oblongis subcuneatis retusis ; pedunculis folium superan- 

 tibus racemo densifloro capituliformi terminatis ; floribus majusculis 

 (lin. 7-8 longis) ; calycis nigricanti-pubescens dentibus latiusculis tube 

 campanulato basi gibboso 3 - 4-plo bi^evioribus ; corolla violacea ; 

 legumine oblongo inflate glaberrirao recto apiculato stipite calyce triple 

 breviori suflfulto. — Valleys of the Rocky Mountains of Colorado Terri- 

 tory, lat. 39° -41°, coll. Hall & Harbour, no. 121. — Stems rather 

 stout. Leaflets 4-7 Hues long. Flowers 20 or more in an open head 

 or short and dense raceme, the rhachis in fruit at most an inch and a 

 half long. Calyx broadly campanulate, very gibbous at the base, 

 3 lines long, the short teeth rather obtuse. Corolla straightish. Ovary 

 very glabrous. Legume 7 -10 lines long, very turgid, its short but 

 distinct stipe about a line long. — This very well-marked species oc- 

 curs in no ether collection that I am aware of. Comparison with an 

 original specimen of the little-known Phaca debilis of Nuttall does 

 not confirm my former suspicion that this might be a larger form 

 of that species. It may therefore appropriately bear the name of the 

 assiduous discoverer. 



++ ++ Legumina lineari-oblenga, cylindrica, tenui-coriacea.
