314 Heller : Plants from Western North America 



portion united by a membrane, the lobes about i' mm. wide at the 

 base, gradually attenuate to the mucronate apex, erect in anthesis, 

 spreading, and more or less recurved at maturity ; corolla pale 

 violet, the slender tube barely the length of the calyx, the lobes 

 very small : seeds straw-color. 



Our no. 3098, collected near the mouth of the Potlatch river, 

 Nez Perces county, Idaho, May 20, 1S96, altitude about 120a 

 feet. The plants grew in rich, stony basalt formation in a thinly 

 wooded tract on the right bank of a small stream which empties 

 Into the Potlatch just above the junction of that stream with the 



Clearwater. 



Our specmiens were distributed cither as '' Phlox gracilis'' or 



CoUouiia gracilis^ and are near to that species in most particulars. 



The corolla lobes, however, are much smaller, the sepals broader 



at the base, and the seeds straw-color, instead of light brown, and 



it is of totally different habit, being more like' Microsteris Jinuiilis 



in that respect. The type is in my private herbarium.

In describing this species, I referred to its possible relationship

FT 



Hookei'^s reference to this name, made the following inexcusable 

 statement: "As he gives no description whatever, and does not 

 even mention the color, which is said to be the sole difference, the 

 name is nomcn iiiiduin^ and we have no other clue than that of local- 



w 



ity,*'' The color is mentioned, however, for the bracts are described 

 as yellow and scarlet variegated. I have now no doubt as to the 

 distinctness of my species. In the herbarium of Columbia Uni- 

 versity there is now a single specimen besides my own C. Intca 

 collected by Professor C. V. Piper of Pullman, Wash.
