Rocky Mountain Flora 255 



distinct rachis ; leaflets 4, linear to oblong or of the lowest leaves 

 obovate, i — 1.5 cm. long or the lower shorter: peduncles 4-5 cm. 

 long, I— 2-flowered ; bracts linear, about equalling the calyx : calyx 

 strigose, its tube and teeth each about 4 mm. long ; the latter 

 subulate: corolla about 14 mm. long, strongly curved upwards, 

 the banner much exceeding the wings and keel : pod linear, 

 straight, 2.5-3 '^^^- ^o^b- pubescent. 



This is in some respects intermediate between L. rigidiis and 

 L. WrigJitii, differing from the former in the narrower leaflets, in 

 the shorter peduncles, longer bracts and narrower calyx -teeth and 

 from the latter in decumbent habit, leaves with a distinct rachis and 

 elongated peduncles.

Lupinus depressus sp. nov. 



Perennial, cespitose : stems decumbent, 1-2 dm. long, ap- 

 pressed silvery silky pubescent : petioles slender, 5—7 cm. long, 

 also silvery silky ; leaflets about 7, oblanceolate, usually obtusish, 

 1.5-2 cm. long, densely appressed silvery canescent ; stipules sub- 

 ulate : racemes short, slightly exceeding the leaves ; bracts lanceo- 

 late, short, deciduous : flowers 8—9 mm. long : calyx long-villous ; 

 lips ovate-lanceolate ; the lower about ^3 longer than the upper : 

 corolla light bluish-purple ; banner glabrous, slightly' shorter than 

 the wings. 



Being perhaps most nearly related to L. ininii/iiis, it differs 

 from that in the decumbent or spreading leafy stem and more silk\' 

 pubescence. It grows in gravel on dry mountain slopes, at an alti- 

 tude of about 1750 m.

Lupinus Evermannii sp. nov. 



Perennial and densely cespitose : the numerous stems about 

 1.5 dm. high, slender, erect or ascending, leafy, appressed hairy: 

 petioles 2-4 cm. long, also appressed hairy ; leaflets oblanceolate 

 to linear-oblanceolate, 1—2.5 cm. long, densely canescent on both 

 sides with long appressed hairs; stipules lanceolate, acuminate: 

 raceme very short-peduncled, dense and short ; bracts lanceolate, 

 short, deciduous : flowers 6-7 mm. long ; pedicels and calyx 

 densely pubescent with spreading hairs ; lips of the latter ox-ate-
