6. A. Coulteri, Benth. PL Hartw. 307 (1849) ; .1. Arlfm-SchoUii, Gray, 

 Proc. Am. Acad. vi. 209 ( 1864). Stoutish, 1—2 ft. high, decumbent, often 

 somewhat woody at base, whitish with a short close pubescence : leaflets 

 9—15, oblong or obovate, obtuse or emarginate, ^o in. long : spike loosely 

 10 — 20-flowered : calyx-teeth shorter than the tube : corolla Vg ^^- long, 

 purple : pod ovate, aciite, ?4 in. long, chartaceous, hoary with a short 

 pubescence. — Common in the southern parts of the State, but said to 

 have been found in the first place near Monterey, Coulter. I have seen 

 it to the northward of San Luis Obispo. 



7. A. rremouti, Gray, Pac. E. Rep. iv. 80 (1857). Ascending, 6 10 

 in. high, silvery-canescent : leaflets 9—21, oval, refuse, J^ in. long : fl. 

 subsessile, spreading, purple : calyx-teeth subulate, shorter than the 

 tube : pod chartaceous, round-ovate, acuminate, 1 in. long, obscurely 

 strigulose, mottled with purple. — At Sonora Pass in the Sierra Nevada, 

 thence southward to San Bernardino, and eastward in the desert regions. 

 Belated to A. Coulteri, but of different habit and with rounder pods. It 

 has been referred to A. lentiginosiis ; but that has much smaller pods of 

 a very different texture. 



8. A. leiitig'iiiosns, Dongl. in Hook. Fl. i. 151 (1830). Stoutish, diffuse, 

 glabrous except a minute and sparse roughness upon the stems and along 

 the margins of the 11 — 19 obovate or oblong leaflets : fl. spicate, or fewer 

 and subcapitate, whitish : pod }4 — % ^^- long including the broadly ovate 

 body and abrupt stout beak-like acumination, the whole slightly incurved, 

 firm-coriaceous, white or freckled. — In Sierra Co. or Plumas, if at all 

 within our limits ; for its home is upon the plains of N. E. California, E. 

 Oregon, etc. Readily distinguished from the foregoing by its green and 

 glabrous aspect, as well as by its firm and hard long-pointed and incurved 

 pods. 



9. A. platytropis, Gray, Proc. Am. Acad. vi. 526 (1865). Dwarf, tufted 

 on horizontal rootstocks, silvery-silky : leaflets 7 — 11, obovate : peduncles 

 scapiform, equalling the leaves, capitately few-flowered : calyx-teeth 

 subulate, shorter than the tube : pod round-ovate, scarcely 1 in. long, 

 abruptly pointed, puberulent, white or freckled. — In loose sand and 

 gravel, near the summit of the Sierra at Sonora Pass, Brewer. Apparently 

 not otherwise known within the State ; but it occurs in Nevada. 



H— H— Fods bladdery, 1-celled, the dorsal suture not at all intruded. 



10. A. Hookerianus, Dietr. Syn. iv. 1086 (1847) ; T. & G. Fl. i. 693, 

 under Phaca (1840). Less than 1 ft. high, canescently pubescent or 

 glabrate : leaflets 13—19, rather remote, oblong to linear, 3^ — % in. long : 

 fl. short-pedicelled, whitish : calyx-teeth triangular, very short, the tube 

 cylindrical : pod obovate-oblong, obtuse, tapering to a short scarcely 

 exserted stipe, 2 in. long, thin, glabrous, white or mottled. — Another
