PLANTS FROM SOUTHEASTERN UTAH. 299 



membranous, slightly hispid, 5-toothed; young akenes 

 obovate, hairy, with an inconspicuous toothed margin; 

 mature akenes oblong, keeled on the back, concave on 

 the face, but rigid; 6 mm. long, dark brown, irregu- 

 larly dentate with horny teeth lighter on the edge but 

 not scarious or membranous; pappus a tuft of short hairs; 

 stigmas elongating with the growing akene. 



This is close to Dicoria Brandegei, and occupies the 

 same sandy flats along the San Juan River near the junc- 

 tion with McElmo Creek. D. Brandegei is very abund- 

 ant and blooms later than this species. The flowers of 

 this species are more numerous than those of D. Bran- 

 degei, and there are two fertile flowers to each head in- 

 stead of one. In the akene the teeth of D . Brandegei 

 are said to be connected by an indistinct scarious margin; 

 in this the teeth are not connected except at the base and 

 are more horny there than at the edge. 



Type in the Herbarium of the California Academy of 

 Sciences. 



52. Dicoria Brandegei Gray, Proc. Am. Acad., xi, 76. 



Type locality: "Along the San Juan, between Mc- 

 Elmo and Recapture Creeks." 



Among the hundreds of plants of this species which I 

 saw, there were only two barely coming into bloom. It 

 is conspicuous because of its abundance, its widely 

 spreading habit and its white-veined leaves. Some of the 

 plants cover an area nearly a yard in diameter.* 



This was collected at the type locality. 



* I have scraps of what appears to be a fourth species of Dicoria col- 

 lected by Mr. Alfred Wetherill iu the same region, which I name after the 

 discoverer.
