true Beckwithii^ one from Salt Lake City, Mrs. Joseph Clemens^ 

 the other from Reno, Nevada, Heller 998/. These agree in 

 color characters, and have the lower petals much paler than the 

 deep violet upper ones; but indeed far from being white. I am 

 confident that further field study will substantiate my conclusion 

 that the white petaled northern form is no mere variation with- 

 out fixed color characters. 



The variety cachensis is common on sage brush covered 

 gravels in the southern end of Cache valley, Utah, and evidently 

 occurs northward and westward over much of northern Utah and 

 southern Idaho. According to reports of my students, it is found 

 as far south as Brigham City, Utah, and I have seen specimens 

 from .southern Idaho, north of the Snake river, tho such are not 

 at hand for definite recording. My own collections of it are: 



Ut.\h: 2084^ Logan, Cache county, 6 April, 1910; 2102^ 

 Wellsville, Cache county, 15 April, 1910; ^j^j, Collinston, Box

/ Tragopogon porrifolius luteus Fr. ? On my first visit 



to Preston, Idaho, in July, 1909, a Tragopogon was very com- 

 mon and conspicuous in full fruit. It looked so much like T. 

 Porrifolius, which is not uncommon about Logan, twenty miles 

 southward, that I unhesitatingly passed it by as such. I was 

 therefore much surprised, in June, 1910, to find the plant uni- 

 formly with bright yellow ligules, tho otherwise with the floral 

 characters of the purple flowered species, and not possibly con- 

 fusable with T. pratensis, the only yellow flowered form reported 

 from North America as yet. I was unable to properly care for 

 the material collected at the time, so that good specimens were 

 not obtained. The determination is, of course, but tentative, 

 and was suggested to me by Mr. H. H. Bartlett, without speci- 

 mens to consider; but the plant is so like our common T. porri- 

 folius that it might well be considered a color variety of the 

 same, at least until its exact relationship can be learned. It is, 

 of course, an introduction from Europe.
