* Lupinus pseudoparviflorus. 



Stems several from a woody caudex, 3-6 dm. high, striate, finely 

 silky-strigose, rather leafy, slender and erect ; stipules lanceolate, 

 about 5 mm. long, early deciduous; petioles slender, the lower 

 about twice as long as the leaves; leaflets 8-10, oblanceolate, 3-5 

 cm. long, acute or mucronate, finely silky-strigose beneath, glabrate 

 above; raceme 1-1.5 ^""^- ^o"S' loosely flowered; bracts almost 

 subulate, a little longer than the pedicels, very early deciduous ; 

 pedicels and calyx densely appressed-silky, very gibbous or gen- 

 erally somewhat spurred above; banner very broad, blue, slightly 

 lighter in the center ; wings and keel light bkie with darker veins, 

 the former a little longer than the banner; corolla about i cm. long, 

 perfectly glabrous ; ovary hairy ; ovules 4-6. 



Nearest related to L. parz'ifiorus, from which it differs mainly in 

 the narrower leaves and in the pubescence and form of the calyx. 

 In L. farvljioriis the leaves are mostly obovate and rounded and 

 mucronate at the apex, and the calyx is villous with spreading pu- 

 bescence, and has no indication of a spur. 



In open woods, at an altitude of 2000-2-300 m.

 what exceeding the leaves, the upper often much shorter ; leaflets
