1889, and until recently supposed to be the L. parviflorus Nutt., to 

 which, however, it can hardly be very closely related. 



Lupinus gracilentus. 



Stems tufted, erect, slender, leafy, 2 feet high ; herbage green and 

 not conspicuously pubescent (scantily jjilose or villous under a lens) ; 

 lowest leaves on slender peduncles, 6 or 8 inches long, and with nar- 

 row, adnata, long-setaceous-pointed stipules ; leaflets about 7, linear- 

 falcate, acute, 2 inches long, more or less ; racemes terminal only, 

 and on long, slender, naked peduncles ; flowers in 4 to 6 distinct 

 verticils ; calyx-tube slightly gibbous at base ; corolla rather small 

 (4 or 5 lines long), blue ; keel strongly falcate-acuminate, naked, 

 slightly surpassing the wings, these longer than the banner; ovary 

 hirsute; immature pods appressed-villous. 



In the Tuolumme Canon of the Sierra Nevada, California, 1889, 

 Messrs Chesnut and Drew. 

 Lupinus Covillei. 



Erect, stoutish, 2 or 3 feet high, the striate stems leafy up to the 

 subsessile, long raceme; herbage rather light green, soft to the 

 touch, with a hirsute pubescence ; petioles about equalling the leaf- 

 lets, these about 9, linear-lanceolate, 1* to 2* inches long; racemes 

 elongated, the flowers in distinct verticils ; bracts fully equalling the 

 flowers, linear-filiform, somewhat persistent; calyx and pedicels 

 densely hirsute (as also the young pods) ; corolla purple, h inch 

 long, the banner slightly shorter than the wings ; keel not strongly 

 falcate, naked, or with a few hirsute hairs below the tip. 



Near Farwell Gap, in the Sierra Nevada of California, at an alti- 

 tude of 10,000 feet, August 30, 1891, Messrs. Coville and Funston, 

 n. 1,746. The species is also in the State Survey collection, from the 

 same region, and was evidently mistaken for the far northern and 

 very different L. lepidus,
