44 PLANTS WRIGHTIAN.E. VI 



calycis villosi dentibus lineari-subulatis tubo campanulato tequilongis ; corollge vio- 

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

 tibus sutui-a dorsali introflexa semibiloculaiibus polyspermis. — Pebbly bed of a 

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

 noo3.) — Root perpendicular, penetrating deeply. Stems a foot or more in length, 

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

 ovate-lanceolate, acuminate ; the upper united to the middle, the lower almost to 

 their summits. Leaves 1] to 2 inches long. Leaflets 5 or G lines long, one or two 

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

 silky-canescent, especially beneath, with rather long and loosely-appressed straight 

 hairs. Raceme one or two inches long, 1 2 - 20-flowered ; the flowers at first con- 

 tiguous, but not densely croAvded, 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. Corolla deep violet in the dried specimens ; the keel tapering and some- 

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

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



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

 flexuoso e radice perenni; stipulis triangulato-subulatis ; foliolis 7-11-jugis ob- 

 longo-linearibus oblongisve obtusis nunc retusis (6- 10 lin. longis) ; racemis longe 

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

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

 oblongis inflatis chartaceis glabellis apiculatis facie ventrali rectiusculis dorsali 

 gibbosis polyspermis. — Phaca Fendleri, Gray, PL Fendl. p. 36. (1004.) — Pine 

 hills, 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 likewise gathered in fruit), having shorter and broader, oblong 

 or elliptical, 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. (Piiaca) Sonor.5; (sp. nov.) : argenteo-sericeus, humilis ; caulibus decumbenti- 

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

 opposito pi. m. coalitis ; foliolis 7 - 8-jugis anguste oblongis lanceolatisve acutatis 

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

 sericei dentibus setaceis tubo a^quilongis ; corolla purpurea ; leguminibus lunatis 

 turgidis chartaceis puberulis, suturis baud introflexis. — Mountain valleys, 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 very short pedicels. Legumes barely 

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

 somewhat compressed, the upper suture acute. Seeds 8 or 10. — This bears some 

 resemblance to A. (Phaca) gracilentus. No. 159 of Fendler's collection : but that is 

 not silky, and has larger and nearly straight pods, smaller and paler flowers, &.c.
