PLANTS FROM SOUTHEASTERN UTAH. 317 



of in terminal clusters. The fruiting bracts are not com- 

 pressed and the horny appendages are so numerous that 

 it is impossible to distinguish the margins from the sides 

 of the bracts. The name was suggested by a fanciful 

 resemblance of the fruit to the Gorgon's head. 



117. Another form growing in the same region is 

 smaller with fewer branches, leaves thicker, more ap- 

 pressed-scurfy; the fruiting bracts have shorter processes 

 disposed to be somewhat spine-tipped; the pedicels are 

 stouter and less attenuated. It appears to be a starved, 

 less protected plant than the type, and from its open sit- 

 uation I judge this to be the explanation of the difference 

 rather than to consider it even a variety. 



The type was collected near Recapture Creek, along 

 the banks of the San Juan River, growing in masses 

 mixed with other species of Atriplex, etc. The smaller 

 form grew in the open where the ground was drier and 

 less fertile.

Type locality: "Hillsides, among fragments of creta- 

 ceous sandstone on the San Juan River, near the bound- 

 ary between Colorado and Utah." 



Collected abundantly in a similar locality on a hill op- 

 posite Hill's Ranch, on McElmo Creek not far from the 

 boundary, probably the type locality. 



It was abundant there, but seen in no other place; 

 though I was on the lookout for it constantly. Two forms 

 grow together apparently under the same conditions. 



(a) This grows to a height of 4-5 dm.; leaves, in- 

 cluding the petiole, 3-4 cm.; fruiting bracts 4-6 mm. 

 wide. 



(b) This is less than 2 dm. in height; leaves not ex- 

 ceeding 2 cm. in length, inclined to be revolute espec-
