valvis turgidis. — Rocky Mountains on the British Boundary, probably 

 not at great elevations, Bourgeau, in Palliser's expedition (ex herb. 

 Kew.). — Leaflets 7 to 12 lines long, a line or a line and a half wide, 

 rather rigid. Calyx short-campanulate, the teeth not half the length 

 of the tube, often still shorter. Corolla 4^ to 5 lines long, curved ; the 

 carina produced into a narrow inflexed tip. Legume scarcely if at all 

 exceeding a line in width, straight. It has a short stipe hidden in the 

 calyx, like that of A. Jlexuosus, which is the species of Scytocarpi most 

 approaching the Homalohi in the narrowness of its pod, and which the 

 present species somewhat resembles. But the flowers of this are larger 

 and differ much in the narrow and inflexed tip to the keek The pods 

 with turgid valves resemble those of A. colUnus. But its near affinity 

 is with A. campestris and A. decumbens, from which the glabrous 

 legumes, on a manifest though short stipe, distinguish it.

 cinereo-pubescens ; caulibus cgespitanti-decumbentibus conferte foliosis 

 stipulis majusculis ; foliolis 3 - 5-jugis oblongis lanceolatisve acutis 

 pedunculis folium suba^quantibus 2 - 5-floris ; floribus approximatis 

 racemosis patentibus ; corolla violacea, carina breviter incurva obtusis- 

 sima alis satis vexillo dimidio breviore ; legumine lineari-oblongo com- 

 planato sericeo-puberulo (lin. 4-5 lin. longo). — Elevated regions of 

 the Rocky Mountains, near the Bi'itish Boundary. The fruit, that of 

 a genuine Homalobus, is described from Bourgeau's specimens. Corolla 

 4J- to 5 lines long, curved, the large vexillum reflexed.

 ticaulis, cinereo-puberulus ; caulibus diff"usis (spithamasis) gracilibus 

 laxe foliatis ; stipulis majusculis, superioribus ad medium connatis ; 

 foliolis lato-linearibus oblongisve plerumque obtusis ; pedunculis folium 

 longe superantibus 5 - 12-floris ; floribus in racemo sparsis ; coi'olla et 

 calyce fere praecedentis ; legumine juvenili ovato-oblongo canescente. 

 — Valley of Columbia River, Dr. Lyall (ex herb. Kew.), and, if the 

 same, of its tributary the Spokane, Douglas. Described from Dr. 

 Lyall's specimens (no. 7), and (the fruit being wanting) referred here 

 on account of its resemblance to the preceding species. Douglas's
