The only difference which I can see between this variety 

 and the type is in the shorter style, which is generally 

 shorter than the septum of the mature pod; the plant 

 grows in a different zone, the type species being found 

 among the junipers of the Great Basin region, and the 

 variety occurring chiefly in the regions below the juniper 

 belt as far down as the upper Larrea belt. 



Lepidium scopulorum. L. heterofhyllum (Watson, Am. 

 Nat. 9, 268) Jones, Zoe, 4, 267. 



The latter name is preoccupied. Dr. B. L. Robinson 

 has called my attention to this and I have suggested this 

 name in its place. 



Lepidium integri folium Nutt. JL. Utahense Jones. 

 Having an opportunity to compare my material with au- 

 thentic specimens I find no appreciable difference. 



Lepidium Oreganum Howell seems to be the same as 

 L. dictyotum. His specimen examined is from Rogue 

 River, Oregon, April. 



Viola pinetorum Greene is only a coarsely toothed form 

 of V. aurea, it has a long thick root, 6' long. Some 

 specimens of undoubted V. aurea without the other char- 

 acters of V. pinetorum have coarsely toothed leaves. 



Biscutella Californica is deliciously fragrant. 



Greggia camporum var. linearifolia (Watson, P. A. 

 A. 18, 191). G. linearifolia Watson 1. c. 



Cleome integrifolia var. angusta. No. 6057a. 



Pods very narrowly -linear and cylindrical. This is 

 the usual form indigenous to the West. Plants intro- 

 duced from Mexico are like the typical form.
