calycis villosi dentibus lineari-subulatis tubo campanulato sequilongis ; corollae vio- 

 lacese carina apice angustata producta ; leguminibus lineari-oblongis arcuatis puben- 

 tibus sutura dorsali introflexa semibilocularibus polyspermis. — Pebbly bed of a 



w , 



stream, and on hills under pine-trees, near the copper mines, New Mexico ; Aug. 



Root perpendicular, penetrating deeply. Stems a foot or more in length, 

 y strigose-hirsute, leafy throughout. Stipules scarious, 3 lines long, hairy. 



•lanceolate, acuminate ; 



the middle 



their summits. Leaves l-} to 2 inches long. Leaflets 5 or 6 lines long, one or tw 

 lines wide, linear or oblong, silky-hirsute (like the peduncles, &c.), and when youn 



especially beneath 



loosely-appressed straight 



hairs. Raceme one or two inches long, 12-20-flowered; the flowers at first con- 

 tiguous, but not densely crowded, 4 or 5 lines long, showy. Bracts rather per 

 sistent, lanceolate-subulate, villous, as long as the calyx. Calyx-tube a line and a 

 half long. CoroUa deep violet in the dried specimens ; the keel tapering and some- 

 what prolonged at the apex, but obtuse. Ovules about 24. Liiraature legume 8 

 or 9 lines long, with a broad and shallow dorsal groove. Mature pods not seen. 

 A. (Phaca) Fexdleri: parce striguloso-puberulus ; caule adscendente gracili 



flexuoso e radice perenni; stipuHs triangulato-subulatis ; foHolis 7-11-jugis ob- 

 longo-Unearibus oblongisve obtusis nunc retusis 



(6 - 10 lin. longis) ; racemis 



pedunculatis patentibus 10 - 20-floris laxis folium superantibus ; floribus purpureis 

 patulis ; calycis nigro-puberuli dentibus subulatis tubo brevioribus ; leguminibus 

 oblongis inflatis chartaceis glabelhs apiculatis facie ventrali rectiuscuUs dorsaU 

 gibbosis polyspermis. — Phaca Fendleri, Graif, Pl, Fendl. f. 36. (1004.) — Pine 

 hiUs, from the Mimbres to the copper mines, New Mexico ; Oct. — The specimens 

 are entirely in ripe fruit, and, except that they are larger, correspond with Fendler's 

 No. 158 (which was Ukewise gathered in fruit), having shorter and broader, oblong 

 or eUiptical, and often emarginate leaflets; but some specimens make a near ap- 

 proach to Fendler's No. 157 (flowering specimens), to Avhich. they may be safely 

 united. The ripe pods are from 9 to 12 lines long, and 4 or 5 in diameter. — I 

 defer to Mr. Bentham in uniting Phaca to the vast genus Astragalus. 



A. (Phaca) S0NOR.E (sp. nov.) : argenteo-sericeus, huimlis ; caulibus decumbenti- 

 bus gracilibus e radice perenni ; stipulis ovatis scariosis, inferioribus inter se folio 

 opposito pl. m. coalitis ; foUolis 7 - 8-jugis anguste oblongis lanceolatisve acutatis 

 utrinque scriceis; pedunculis folio mox longioribus; racemo 8-12-floro; calycis 

 sericei dentibus setaceis tubo aequilongis ; coroUa purpurea; leguminibus lunatis 



o 



puberulis, suturis haud introflexis 



between 



the San Pedro and the Sonoita, Sonora ; Sept. (1005.) — Stems a span or more in 

 length, leafy. Leaflets 3 or 4 lines long, canescently silky and silvery beneath, and 

 hardly less so above. Peduncle 2 or 3 inches long. Flowers 4 to 5 lines long, ap- 

 proximate. Bracts a little longer than the verj short pedicels. Legumes barely 

 half an inch long, 2 to 3 lines in diameter, falcate-incurved, pointed, turgid, but 

 somcwhat compressed, thc upper suture acute. Seeds 8 or 10. — This bears some 

 resemblance to A. (Phaca) gracUcntus, No. 159 of Fendler's coUection: but that is 

 not sUky, and has larger and nearly straight pods, smallcr and paler flowers, &c.
