Plumas Co., 1876. The late summer slate, with capsules from 

 apetalous flowers, known only in a sheet collected by my former 

 pupil, Air. Milo S. Baker, in Big- Valley, Lassen Co., 3 July, 

 1893. At the time of my proposing the V. cognata segregates 

 from / *. cucullata I placed these Californian and some other Pa- 

 cific coast forms tentatively under V. cognata; but in the light 

 of additional material I see cause to separate them." 



Specimens collected in the mountains west of Reno, espe- 

 cially in Hunter creek canyon, seem to belong tot'iis large flow- 

 ered species. It inhabits wet grassy places along and near 

 streams. The species probably has quite an extended range 

 along the eastern base of the Sierra Nevada. 



Viola blanda Willd. Hort. Berol. pi. 24. 1806. 

 We have a specimen from Slide mountain, Washoe county, 

 collected in July, 1907, by C. L. Brown, which is referred to 

 this species for the present. I had supposed that it would prove 

 to be / '. Macloskeyi Lloyd, Erythea 3: 74. 1895, but it does 

 not agree with the description of that species. While having 

 the purple striped petals of V. blanda, the base of the leaf is not 

 cordate, as shown in the Illustrated Flora. Future stud)- of 

 this group will probably demonstrate that our plant is unde- 

 scribed. One should not expect to find V. blanda on this side 

 of the continent.
