3. P. orbicularis ; repens, (foliolis corollisque exceptis) glandulis elevatis scabra, caule 

 gracili, petiolis pedunculisque longissimis (spitliamaeis ad pedalem), foliolis (3) rotundato- 

 cuneatis obtusissimis pubescentibus nigro-punctatis, stipulis parvis ovatis membranaceis, 

 spicis brevibus nigro-villosis, bracteis calycisque lacinia inferiore corolla tn aequantibus. — 

 Lindl. Bot. Reg. t. 1971. 



Flowers rather large, purple. Leaflets two inches and more long. 



4. P. physodes ; erecta glabriuscala herbacea, foliolis (3) late rhombeo-ovatis punctatis, 

 stipulis parvis lanceolatis membranaceis, racemis laxis pedunculatis folio longioribus, calyci- 

 bus demum inflatis glandulosis corolla dimidio brevioribus dentibus brevibus subasquanti- 

 bus. — Douglas. — Hook. Fl. Bor. Am. 1. p. 13(5. Torr. et Gr, Fl. 1. p. 301. 



Our former specimens from the Columbia, with only withered flowers, led us into an error with respect to 

 the relative length of the calyx and corolla. The corolla is in reality twice the length of the calyx. After 

 flowering, the latter becomes longer and inflated, and quite encloses the I-seeded legume.

Hab. Between Bruneau and Onyhee Rivers, Snake Country. (Tolmie.) 



I. Amorpha Californica ; fruticosa pubescens, ramulis petiolisque glandulis rigidis 

 acutis aculeatis, foliolis ellipticis obtusis subtus nigro-punctatis, calycibus striatis pubes- 

 centi-canis 5-fidis glandulosis laciniis lanceolatis glandula terminatis, stylo exserto recurvo 

 acuto germineque globoso-villosis. — Nutt. in Torr. et Gr. FL I. p. 306. 

 A very distinct species, most allied perhaps to A. fruticosa. 



1. Phaca macrodon ; erecta dense pubescenti-canescens demum glabriuscula, caule 

 angulato, foliolis 1 1- 13-jugis oblongo-lanceolatis obtusis apiculatis brevissime petiolulatis, 

 stipulis parvis lanceolato-acuminatis persistentibus, pedunculis folio subbrevioribus, 

 racemis elongatis multifloris, bracteis subulatis membranaceis longitudine pedicellorum, 

 calycis tubo ovali, dentibus filiformi-subulatis flexuosis tubum aequantibus corolla parum 

 brevioribus. 



A tall growing species. Leaves six inches long, pubescenti-villous and hoary, in the older leaves as well 

 as on the pale reddish-brown angular stems, at length less hairy and almost glabrous. Flowers apparently 

 yellow, at first patent, then reflexed ; the corolla a good deal curved upwards. Calyx with singularly long 

 flexuose, narrow, subulate teeth. Ovary linear, compressed, silky. 



2. P. leucophylla ; erecta canescenti-sericea, caule obscure striato, foliolis 14-18-jugis 

 oblongo-lanceolatis obtusis brevissime petiolatis, stipulis parvis subulatis membrana- 

 ceis, pedunculis folio duplo longioribus, racemis oblongis densiHoris subspicatis, bracteis 

 subulatis pedicellum brevissimum aequantibus, calycis ovalis dentibus lato-subulatis brevi- 

 bus rectis subajqualibus Astragalus leucophyllus. Torr. et Gr. Fl. 1. p. 336. 



Habit of the preceding, and of several acknowledged Phaca, on which account, in the absence of fruit, I 

 refer it to the present genus. Flowers large, probably cream-coloured when fresh, erecto-patent.
