NOTES FROM NORTHERN UTAH— IV 

 By C. p. Smith 



Viola Beckwithii cachensis n. var. 



Fetalis superioribus pnrpureis-violaceis, petalo inferiorique 

 petalis lateralibus albis puris, unguibus flaventibusque purpureis- 

 striatis. 



Upper petals violet-pnrple, lower and lateral petals pure 

 white^ the claws yellow and purple-veined as in the species. 

 Otherwise with the characters of true Beckzvithii. 



This is evidently the northern Utah and southern Idaho 

 representative of the "bird-foot violet" group, and seems to be 

 unrecognized as a definite form. Twice or more has it been de- 

 termined for me as V. Beckivithii^ but as the color difference is 

 very marked and constant, to me it appeals as well worthy of a 

 name. 



As to variations in the color of the lower petals of V. Beck- 

 withii^ I have found but one reference in literature, where M. E. 

 Jones (4) describes a white-petaled form from Weiser, Idaho. 

 This is, hewever, presumably referable to the variety named 

 above. The original description (1) of V. Beckivithii says, 

 "lower petal barely saccate at the base, purple, with yellow 

 claws, the upper shorter and deep violet." Heller (5), who 

 knows the species as it grows at Reno, Nevada, has written, 

 "upper petals deep purple, lower ones much paler." Garrett (6), 

 who presumably knows the plant in the field, about Salt Lake 

 City, follows the original description without reference to any 

 variation-. I have before me specimens of two collections of
