﻿prove to be a form of G. finnatipda. In view of the 

 imperfection of the original specimen, I thought best to 

 leave it unpublished till better material could be collected. 

 Abundant material is now at hand, and I take pleasure in 

 dedicating this species to its discoverer. This grows on 

 very hot and dry talus and even on cliffs. 



No. 5701a. July 31, 1894, Capitol Wash, Utah, near 

 the Henry Mountains, 5000 alt., on sandstone rocks, in 

 very arid places. 



This plant has the habit of G. Watsoni, but is nearest 

 to G. floribanda; whole plant greenish, but rough, with 

 short, stiff, not dense pubescence throughout; tufted in 

 dense bunches and branched below, stems 2-4' long, 

 terminated by a dense head of sessile flowers, 5-10 in the 

 head; stems white ; leaves pedately 3-5 parted, filiform, 

 rigid, straight, acerose, involute, i-nerved, 5-6" long, 

 somewhat longer than the internodes, not reduced above, 

 and heads with similar bracts; nodes enlarged; calyx 

 -cylindrical, tube 3" long and lobe 1" long, very hyaline 

 between the angles; corolla white, 1-2" longer than the 

 calyx, narrowly oblong lobes, 2-2 k" long; seeds 2 in each 

 cell, linear. The heads are seemingly a little glandular 

 and the flowers are vespertine. 



This plant grows on the hottest red sandstone rocks in 

 little crevices and pockets, and is quite fragrant. 



No. 5445m June 16, 1894, near Emery, Utah, in clay, 

 7000 alt. 



Corolla cuneate and tridentate, rotate-spreading, and 

 flowers smaller and shorter than in the type. This is 

 figured by Watson in King's Report along with the type, 

 but when growing it is conspicuously different from it, 

 though often found growing with it.
