﻿No. 5297I. May 26, 1894, Pahria Canon, Utah, 5300° 

 alt., in sand. 



After looking over all the specimens obtainable on these 

 two species, I can only consider A . interior Coville as a 

 geographical variety of A. linear if alias, as transitions 

 seem to occur at all points. Mrs. Brandegee has already 

 called attention to this as a variety. 



Gymnolomia multiflora var. annua. All the forms 

 of this species growing in our northern mountains are 

 perennial, as described by Nuttall; those growing on the 

 arid plains of the south are annual, and with quite a 

 different habit; the heads are decidedly conical, the 

 plants are more delicate and slender, often only a few 

 inches high. The variety ranges from southeastern Utah 

 to Mexico and westward, but I have never seen it in the 

 Great Basin. 



No. 51 10. April 26, St. George, Utah, in red sand. 

 on the slopes of Triassic rocks, at 3000 alt., growing in 

 tangled clumps about three feet high. Soil a little alka- 

 line. 



Shrub 3-6 high, with rounded top and long, slender. 

 intricately interlaced branches, closely and permanently 

 woolly, branches rather tortuous; primary leaves 6-12" 

 long, linear-spatulate, tomentose, straight or nearly so, 

 horizontal to somewhat deflexed, never hooked, becoming 

 long slender spines, 1' long, like those of Ofuntia rutila, 

 but not so long; secondary leaves fleshy, smooth, linear, 

 but a trifle widened above, 6" long ; scales 3" long, oblong ; 

 heads 4" long, on a peduncle 1" long or less; flowers 

 about 6-10 in a head; young branches never elongated. 

 This differs very markedly from the type in the long 

 spines and in its habitat, but there 1
