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

 obovate, 1-1.5 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 e.xceeding the wings and keel : pod linear, 

 straight. 2.5-3 ^ni. long, pubescent. 



This is in some respects intermediate between L. rigidiis and 

 L. W'riirhtii, 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 silver}' 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 )i longer than the upper : 

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

 the wings. 



Being perhaps most nearly related to L. iiiininms, it differs 

 from that in the decumbent or spreading leafy stem and more silky 

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

 tude of about 1750 m.

Lupinus Evermannii sp. nov.

 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,
