Viola cTirysantha var. JVevadensis. (Kellogg.) Fig. 72. 



Stem short, partly subterranean, slightly pubescent, cespitose. 



Leaves both radical and canline, on long petioles, bipinnatifid, 

 segments linear-lanceolate, acute, glabrous above, pubescent or 

 scabrulose beneath, margins scabrous and sometimes also pubescent, 

 points tipped with a gland. 



Stipules linear-lanceolate, falcate, entire or sparsely dentate, often 

 half to three-fourths of an inch in length, and when thus fully de- 

 veloped, sub-lobed and similar to the lea,ves. Peduncles longer 

 than the leaves, sub-glalDrous, rarely a few scabrous elevations and 

 scattering hairs. Bracts mmute, lanceolate, acuminate ; margins 

 subscarious, swelled or produced at the base on the back, situated 

 above the middle ; sepals ovate-oblong, acute, produced and emar- 

 ginate at base, margins naked or scabrous, (rarely a few scattering 

 hau"s on the back), three nerved. 



Flowers very large, petals obovate-cuneate, the two upper yel- 

 lowish in front, purple on the back, claw also purple in front, (a 

 variety with smaller flowers has the upper petals deep indigo on 

 both surfaces) ; lateral petals somewhat papillose bearded from a 

 little mons nearer the upper margin ; lower petals brightly yellow, 

 with dark purple veins at the base, lowest with a short spur. Style 

 clavate, curved, sub-rostrate, sub-lipped, compressed, short bearded 

 below the summit, foramen large, nearer the somewhat protuberant 

 obtuse beak. 



In no specimens of this plant from the interior have we been able 

 to find all the stipules " entire," as V. cJiri/santha is described by 

 Sir Wm. Hooker ; the sepals also are not " cilliate," nor the lateral 

 petals " glabrous ;" the spur, although short, is not wanting, cer- 

 tainly not " slightly saccate." The scabrous and glandular leaves, 

 it would seem, are features worthy of notice. 



Lupinus eervvniis. (Kellogg.) Fig. 73. 



Stem herbaceous, silky appressed pubescent throughout, with 

 short fulvous villi. A robust plant of a pale greenish, ocherish hue, 

 six inches to one foot high. 



Leaves large, petioles stoirt, strongly three to five nerved at the 

 somewhat clasping base ; stipules very short, subulate, adnate, 

 (about one-quarter of an inch in length). Leaflets large, (one to 

 two inches long, or one-quarter to one-third the length of the peti- 

 ole) six to seven, obovate, cuneate, obtuse, (rarely sub-acute) 

 acutely mucronate, mid rib thickened, more ferruginous satiny be- 

 neath ; flowers pale blue, (?) somewhat verticillate in an elongated 

 pedunculate spike ; bracts very short, subulate from a broad base,
