CONTRIBUTIONS TO WESTERN BOTANY. 7 II 



Phlox longifolia var. hrevifolia Gray. 



No. 5098J. April 23, 1895, ten miles south of Black 

 Rock Spring, Arizona, in gravel, in the juniper belt, 

 4500° alt. No. 5286V. May 23, 1895, Kanab, Utah, 

 5300° alt., in red sand. These forms have linear-oblong, 

 obtusish leaves, i' or less; the calyx has long and hyaline 

 interspaces greatly enlarged, and folded outward so as to 

 make the calyx seem ovate at base. The replication of 

 the calyx is a character of no permanent value. 



Phlox longifolia var. gladiformis. 



No. 5208c. May 11, 1894, Cedar City, Utah, 6500° 

 alt., in gravel, on slopes. 



This has the habit of P. Doiiglasii, but is less compact; 

 leaves densely clustered around the sessile flowers, loosely 

 imbricated below, or the nodes 3" long, leaves about iV 

 long, all subulate-lanceolate, pungently acute, thick and 

 stiff, midrib and margins prominent, the latter a little in- 

 volute ; whole plant, even to the flower, glandular and 

 sparsely floccose-hairy, but green; calyx lobes a little 

 over half the tube; corolla tube nearly double the calyx, 

 lobes oval, entire. The plants are loosely ceespitose, and 

 would seem to be hybrids between longifolia and Doug- 

 lasii, were it not for the fact that they are very abundant 

 in the locality where found. It grows on north slopes of 

 gravelly hills at the mouth of the canon of Cedar Creek. 



There seems to be a complete transition from P. longi- 

 folia to P. Doiiglasii through the above variety and the 

 var. brevi folia. 



Phlox austromontana Coville seems to deviate in no 

 constant character from P. Doiiglasii, the replication of 

 the calyx relied upon as a crucial character, proves of 

 no value, as it varies from nothing to a wide fold. I can- 

 not refer this to P. s-peciosa, as Gray has done.
