to white. Banner roundish, -with a long reflected claw, pubescent 

 on the back ; wings oblong, externally puberulent towards the 

 apex, &c.; keel cihate ; stigma naked ; pods hairy, four-seeded. 



This species is near L. laxifiorus. The spur is remarkably long, 

 exceeding the pedicels ; but (X. laxifloi'us) is described as havmg 

 blue flowers. This, as before stated, has no white flowers, but half 

 the calyx, including the spur, is also white ; the stem certainly is 

 not " glabrous," as some have described laxifiorus, nor are the 

 petioles of the leaves short, nor the points of the leaflets obtuse ; 

 the stiprdes are neither subidate nor caducous, nor is the raceme 

 what we should designate as loose and elongated. 



Finally, the white flowers and half colored calyx, Avhich could by 

 no means be spoken of as slightly saccate, induces us to consider it 

 as a new species. 



Lupinus caudatus (Kellogg). Fig. 61. 



Stem persistent, somewhat decumbent ; leafy and branching, sil- 

 very or satiny, appressed pubescent throughout. 



Leaflets five to seven, hnear-lanceolate, acute, mucronate, nar- 

 rowed towards the base, about as long as the petiole. 



Stipules persistent, small lance-acumuiate. 



Flowers blue, scattered and sub-verticillate, floral portion about 

 twice the length of the peduncle, or two or three times the length 

 of the petioles. 



Bracts caducous, twice the length of the pedicels ; calyx tubular 

 campanulate, upper lip straight,, two-toothed, (not colored) short 

 and somewhat subulately spurred at the base, (spur erect nearly 

 half the length of the pedicel) ; lower hp entu-e, elongated, carin- 

 ate ; hnear bracts conspicuous ; banner satiny pubescent on the 

 back, chiefly along the middle portion ; wings with an erect claw. 



Keel, silky-cihate. 



Stigma, naked. 



Legumes (embryo) linear, silky ; seeded. 



Closely aUied to L. calcaratus (Kellogg). But the general 

 appearance is quite distinct, being very silvery sericeous, with blue 

 flowers. The calyx is not colored ; the upper Up straight ; the spur 

 short, sharp and erect ; the leaflets straight and radiating, only 

 five or six in number ; the flowers also fewer, and the spike less 

 crowded. Found in the same localities, but more rare.
