Viola aurea (Kellogg). Fig. 54. 



Stem short, erect, ridged bj the decurrent petiole to the leaf 

 below. 



Canescent hirsute (but beneath the dense white hairs the hue of 

 the w^hole plant is yellowish green, more observable on the stem, 

 petioles, veins and peduncles). 



Stipules adnate, subscarious, lanceolate acuminate, entire, ob- 

 scurely nerved. 



Leaves ovate, sub-acute ; base cuculate, entire, tapering into the 

 petiole and thence decurrent, coarsely sub-repand dentate, three- 

 nerved triplinerved above ; densely canescent hirsute above and 

 below ; petioles one to two inches in length, or about twice the 

 length of the lamina, sub-winged, base and stipule encircling the 

 stem. 



Peduncles longer than the leaves ; bracts opposite, minute. 



Sepals ovate, acute, three-nerved, glabrous vt'ithin ; margins 

 ciliite. 



Corolla pure brilliant yellow ; wings sraooth ; lower petal simply 

 saccate. 



Style capitate, curved, laterally bearded ; foramen nearly central. 



Capsule (in embryo state) villous at the apex. 



Brought by Mr. C. W. Dorr from Nevada Territory. An Alpine 

 species, almost woolly in its external appearance. 



Viola Sequoiensis (Kellogg). Fig. 55. 



Minutely pubescent throughout : somewhat angular stem, flexu- 

 ous ; base ascending from a radical four to six inches in length. 

 Lower stipules ovate-lanceolate acumhiate, rarely entire ; middle 

 ovate-oblong, cut-lobed (or dentate) ; middle lobe elongated, all 

 cuspidate-acuminate, about five-nerved ; upper stipules broadly 

 ovate, acute, dentate ; teeth abruptly acuminate-cuspidate or finely 

 subulate-pointed. 



Leaves sub-cordate and reniform (often ten to twelve-lobed and 

 three to four inches broad, on robust specimens of a foot in height), 

 cordate, palmate, three to nine-lobed ; segments more or less oblong- 

 lanceolate, mostly entire, acute, sub-acute or obtuse, glandvdarly 

 mucronate ; margins pubescent and scabrulose ; also beneath, chiefly 

 along the nerves ; on the upper surface less conspicuous.
