* Viola Montanensis. 



Rootstalk slender, but rather woodv ; stems several, slender, 1-2 dm. 

 high, pubescent with short more or less reflexed hairs ; stipules 1—2 cm. 

 long, narrowly lanceolate, tapering at both ends, entire or slightly 

 toothed with narrow teeth, but not dissected ; petioles slender, 3-5 cm. 

 long ; leaf-blade 3-5 cm. long, broadly ovate, often subcordate at 

 the base, obtuse at the apex, finely crenate and pubescent with short 

 hairs; peduncles slender, 3-10 cm. long, with one or generally two 

 narrowly linear bracts scarcely i cm. long below the flower; sepals 

 narrow, linear-lanceolate ; petals blue, with yellowish-white base and 

 spur, obovate, 8-10 mm. long, the lateral a little bearded ; spur 

 about 5 mm. long, obtuse, straight or slightly curved ; stigma 

 slightly beaked ; pod ellipsoid, about i cm. long; seeds pear-shaped, 

 2 mm. long, light isabel-blue. 



Resembles V. arcnaria somewhat in the form of the leaves and in 

 the pubescence, but is a much larger plant, resembling T'. striata 

 somewhat in habit. It differs from both in its narrow subentire 

 stipules, and from the latter also in the pubescence. The latter 

 character also separates it from V. adunca Smith. 



In wet places in open woods, at an altitude of 1500-2000 m.
