CONTRIBUTIONS TO WESTERN BOTANY. 705 



No. 5696. July 30, Cainville, Utah, 4000° alt., in clay. 



Glabrous throughout except some floccose wool on the 

 lower bracts, involucral scales scabrous; stems tufted 

 from a thick perennial root, with the habit of C . Eaton/ , 

 2° high, erect, stout, somewhat branched above; leaves 

 8-12' long and 10-15" wide, running down on the stem 

 nearly the length of the node, pinnatiiid into triangular 

 or oblong lobes, which are short and stout-spinose at tip 

 and minutely so on the margin; heads sessile or nearly 

 so, about iV long, turbinate-C3dindrical, purple flowered; 

 scales regularly imbricated and outer gradually shorter, 

 thin, inner subulate-acuminate, very acute, but not prickly, 

 outermost scales ovate, tapering into a short erect awn; 

 anther tips apiculate; corolla about equaling the lobe; 

 all the scales have a dark line in the middle, are not 

 closely appressed nor rigid; the plants are very leafy 

 throughout, with heads 1-3 in a cluster, which is sessile 

 or nearly so. 



This grows on alkaline clay soil, above Cainville, along 

 the Fremont River. 



If the published characters for other species of this 

 genus hold, then all these here described are good species, 

 but I fear that many recognized species will eventually 

 prove to be forms of polymorphous species, into which 

 some of these may fall. 



Cnicus nidulus. 



No. 5290a. May 25, Pahria, Utah, in red sand along 

 the river bed, 5000° alt. 



Erect from a thick woody, perennial root, 2° high, 

 fioccose-woolly throughout, except the nearly glabrous, 

 seemingly viscid scales; leaves lanceolate, pinnatifid with 

 triangular lobes, which are very stout-spiny ; spines yellow, 

 6" long; heads ovate, 10" long; scales coriaceous, regu- 

 larly imbricated and close-pressed, without green tips,
