BuDDLEiA MARRUBiiFOLiA var. Utahensis ( Coville, 

 Proc. Biol. Soc. Wash., 7, 69). This seems like a nar- 

 row leaved form, as the wider primary leaves are absent 

 in Coville's specimens. 



Ei'iogonum nivale Canby seems to differ in no con- 

 stant respect from E . ovaUfoliinn. 



Eriogonum Riisbyi Greene is E . yonesii Watson. 



Abronia micrantha var. pedunculata. 



No. 5101. April 26, 1894, St. George, Utah, 2700° 

 alt., in red sand. 



No. 5482m. June 22, 1894, Green River, Utah, 4500"^ 

 alt. , in clay. 



No. 5i83t. May 7, 1894, Le Verkin, Utah, in gravel, 

 3400° alt. 



Peduncle double the petiole; fruit often 3 -nerved, 

 emarginate at both ends, often very large, 9" long; flow- 

 ers small; fruit often red. 



This seeins like a hybrid with A. cycloptera, but the 

 latter is not known in the region. The bracts of both 

 these species are ovate, small, 1-2" long, abruptly acute 

 or at least acuminate at apex. 



Atriplex subdecumbens. 



No. 5745. August 6, 1894, Fish Lake, Utah, 9000° 

 alt., in gravelly meadows. 



This species is nearest A. microcarpa and A. argentea : 

 plants slender, subdecumbent, annual, 2-8' long, much 

 branched at the base, mealy throughout, leafy through- 

 out; leaves ovate to lanceolate, with a cuneate base, barely 

 petioled, 6-9" long, rather thin, entire; plants fructiferous 

 throughout in small, sessile clusters; flowers minute, 

 greenish; fruiting bracts i" long, rather cuneate-orbicu- 

 lar to obovate, apex crimped and obscurely dentate, or 

 sometimes toothed, green, sides smooth, back nervose to 

 muricate, seldom if ever with green points, bracts united 

 below.
