 lineari-oblongis obtusis supra glabris subtus appresso-pilosis, stipulis parvis e lata basi 

 acuminatis, inferioribus coalitls, pedunculis folio longiorlbus, racemis elongatls laxis,

Hab. Abundant on elevated and dry fertile soils of the Red Eiver and Assxuaboin, lat. 50°. Douglas. — 

 The habit of this is very similar to the preceding, and I am doubtful if it ought not to be united with it. 

 But the leaves are smaller and narrower, the "Jlowe?-s are purplish and very fragrant," and the legumes are 

 not only smaller than in P. elongata, but straight. What Mr. Douglas has considered as a white-flowered 

 variety, I have referred to the latter species. The cell of the fruit is without a dissepiment, nor is there 

 any introflexion or thickening of the sutures on either side of it. 



4. P.collina; erecta vel diffusa, pilosa, foliolis 9-11-jugis linearibus obtusis basi in 

 petiolulum brevem attenuatis, stipulis parvis oblongis acuminatis, pedunculis folio duplo 

 longioribus, racemis oblongis densis floribus retrofractis^ calycibus tubulosis dense 

 hirsutis, leguminibus (immaturis) linearibus pubescentibus stipitatis deflexis.— Astragalus 

 colliuus. Douglas, MSS. in Herb, HorL Soc, 



Caulis erectus vel declinatus, ramosus, pedalis et ultra, teres, strlatus, pubescenti-hirsutus. Folia remota, 

 digitalia, subsessilia, 19-23.foliolataj foliolis remotis-, unciam longis, angusto-linearibus, obtusis vel retusis, 

 subtus pnecipue pilis brevibus albis curvato-patentibus obsitis, basi in petiolulum brevem attenuatis. StipuleB 

 parvie, oblongae, acuminatse, subfoliacese. Pedunculi foliis subduplo longiores, pubescentes. Racemi 3-4 

 uncias longi, oblongi. Flores arete dispositi, retrofracti. BractetB subulatse, pedicellis erectis paululum

 subulatis tubo triplo brevioribus. Corolla alba, macula magna ut videtur singulo petalo purpurea. Vexillum 

 obovatum apice reflexum, alis carinaque longitudine subaequale. Stamina diadelpha. Germen lineare, 

 stipitatum. Legumen (vix raaturum) calyce plusquam duplo longius, lineare, compressum? submembranaceum, 

 pubescens, uniloculare, basi in stipitem gracilem calycis longitudine, apicem stylo gracili sursum curvato ter- 

 minatum, polyspermum. 



Hab. On the subalpine range of the Blue Mountains, in dry soils. Fl. June, July, 1^ . Douglas, —This 

 plant, which, on an inspection of its legumen, must be referred to the genus Phaca, rather than to Astra- 

 galus, where Mr. Douglas had placed it, is remarkable for its narrow linear leaves, for the sudden deflexion 

 of the flower from the summit of the erect pedicel, for the elongated tube of the calyx, and for the short 

 vexillum. 



5. P. pectinata ; glabriuscula, caule decumbente striato, foliis pectinatis rigidis, foliolis 

 8-10-jugis linearibus subacutis terniinali nonnunquam bifido, stipulis hinc longitudinaliter 

 unitis, racemis folio plerumque longioribus, leguminibus sessilibus ovalibus coriaceis
