brush, but commonly in shallow ravines or other places where 

 there has been more moisture during the winter It is one of 

 the bird's foot violets, the upper petals deep purple, the lower 

 ones much paler. The dissected leaves are gray with a short 

 pubescence, and are crowded and pressed together close to the 

 ground, forming mat-like masses. This close habit is not well 

 shown in dried specimens, for in nature fully one-half of the 

 plant is beneath the ground, the whole of the stem and about 

 half of the length of the petioles being concealed, while in the 

 dried stale it appears as a rather loose and spreading plant. 



The Synoptical Flora gives its range as "from N. W. Ne- 

 vada ( Diamond Mountain, BeckwitK) and adjacent Sierra Ne- 

 vada, California to Oregon." The Diamond mountains of our 

 present maps are situated in the eastern part of Eureka and the 

 western part of Elko counties, extending north and south for a 

 distance of about 100 miles. The type locality may well be in 

 this range, but it is not "adjacent" to the Sierra Nevada, being 

 at least 300 miles farther east. I have recently seen specimens 

 of this species collected near Salt Lake City, Utah.

"V. Austinae. Related to / '. cognata of the Rocky Moun- 

 tains, but the slender rootstocks branching and the plants there- 

 fore tufted; both shorter as to stature and leaves and flowers 

 larger; herbage light-green and altogether and unvaryingly glab- 

 rous: leaves mostly subreniform-cordate, at time of petaliferous 

 flowering 1 to 2 inches broad, the length rarely i' 4 inches, ab- 

 ruptly tapering to the petiole, obtuse, evenly crenate: pedun- 

 cles equalling or slightly exceeding the leaves, bibracteolate a 

 little below the middle: sepals lance-oblong andjihear-oblong, 

 obtusish; corolla commonly an inch wide, petals blue, spatulate- 

 oblong, obtuse, all nearly equal, the lateral pair only scantily 

 bearded, or apparently sometimes not at all so: fruiting pedun- 

 cles of the late apetalous flowers erect, shorter than the petioles, 

 their capsules about 5 lines Ion-.
