above : raceme loosely few-flowe'red : calyx-teeth about half the length of the cam- 

 panulate tube (corolla small and white 1) : pod two thirds of an inch long, 2 lines 

 wide above the middle, thence tapering gradually into the stipe, which is a quarter 

 of an inch long and thrice the length of the calyx. Homalobus multijiorus, Torr. 

 in Pacif. E. Eep. vii. 10, not of Torr. & Gray, El. 



Hillsides, Santa Barbara Co. ; Santa Iflez (Dr. Antisell), Ojai, Dr. G. L. Goodale. 



A. MULTIFLORUS, Gray (the Homalobus disjmr & nigrcsceiis, Nutt., & H. multijiorus, Torr. & 

 Gray, FL), is not known west of the E. Humboldt Mountains, Nevada, nor south of Oregon. It 

 lias white flowers not over 2 lines long, and pods half an inch long, on a stipe not exceeding 

 the calyx. 



32. A. porrectus, Watson. Almost glabrous, a foot or two high : stipules 

 rather large, nearly scarious, the lower united: leaflets 7 to 11, thickish, broadly 

 obovate, about half an inch long : racemes virgate, long-peduncled, loosely many- 

 flowered : pedicels very short, spreading : calyx-teeth slender-subulate, a little 

 shorter than the campanulate tube : corolla " yellow " (apparently cream-color), 

 narrow, half an inch long : pod half an inch or so in length, 2 lines wide, dorsally 

 convex and ventrally almost straight, nearly erect upon an ascending pedicel ; the 

 stipe 2 lines long and barely exceeding the calyx-teeth. Bot. King Exp. 75. 



Trinity Mountains, N. W. Nevada, at 5,000 feet, IVatsmi. Probably to be found within the 

 borders of the State. 



-t- +- Pod two-celled (by strong intrusion of the dorsal suture), turgid ; the cross 

 section broadly obcordately '2-lobed, coriaceous, glabrous: leaflets 7 to 12 pairs. 



33. A. arrectus, Gray. A foot or more high, minutely pubescent or glabrate : 

 stipules distinct : leaflets from linear to oblong, retuse (a third to two thirds of an 

 inch long) : peduncles usually elongated, racemosely 9 - 20-flowered : calyx-teeth 

 much shorter than the tube : corolla yellowish-white : pod narrowly oblong, 

 straight, rather acute at both ends, upright on the ascending stipe which is fully 

 twice the length of the calyx. Proc. Am. Acad. viii. 289 ; Watson, Bot. King 

 Exp. 69. 



Foot-hills of Nevada (Battle Mountain, Watson), and from S. Utah to Idaho. Not yet found 

 very near the borders of California, but to be expected. Flowers two thirds of an inch long. Pod 

 from that to an inch in length. 



34. A. Bolanderi, Gray. A span or two high : stipules scarious and united 

 on the side of the stem opposite the petiole : leaflets oblong-linear or narrowly ob- 

 long, grayish with soft pubescence (a third to half an inch long) : peduncles not 

 exceeding the leaf, almost capitately 6 12- flowered : calyx-teeth slender-subulate, 

 a little shorter than the tube : corolla white with a tinge of purple : pod ovate, in- 

 curved, transversely veiny, less than an inch long, abruptly recurved or reflexed on 

 the conspicuous ascending stipe. Proc. Am. Acad. vii. 337. 



Gravelly soil, in the Sierra Nevada at 6,000 feet and upwards, Mariposa Co. (Bolander, Bridges, 

 &c.), to Sierra Co., Lemmon. Flowers half an inch long. 



* * Pod sessile in the. calyx (or sometimes on a short included stipe) and in size much 

 exceeding it, except in the last species. 



-(- Stems elongated, at least a span or two in length. 

 ++ Flowers about an inch long, few and loose. 



35. A. nudus, Watson. A foot or two high, cinereous with minute appressed 

 pubescence or glabrate : stems branching and flexuous, slender : petioles and angled 

 or flattish rhachis rigid, elongated, bearing a few scattered linear leaflets (varying 

 from 4 to 8 lines long) : peduncles elongated, 5 - 8-flowered : calyx cylindraceous, 

 dark-pubescent ; the lanceolate teeth not half the length of the tube : corolla violet- 

 purple, narrow : pod turgid-oval, glabrous, ascending, rather fleshy, when mature
