sepals. The insertion of the two pairs of stamens unequally is, 

 so far as my field studies go now, a generic and not a specific 

 character of which I will write more at another time. Collected 

 by me at Thompson's Springs, Utah, on the slopes of the clay 

 hills on May 7, 1891. 



Peyitstcmon dcustus, var. pedicellatus, n. var. pedicels two to 

 four lines long, rarely six lines long in the lower flowers; upper 

 peduncles obsolete; all the filaments antheriferous; flowers dirty 

 white and veined with purple; six to eighteen inches high, 

 almost glabrous except the pubescent corolla. Among junipers 

 and pinons at about 8000 feet altitude on gravelly slopes of 

 mountains. July 3, 1891, at Muncy, Nevada, and also at Cherry 

 Creek on the fourteenth of July. Local and rather common in 

 such places. 



^ Eriogomcm rubiflortivi n. sp. Near E. renifo7-me but leaves 

 oval to orbicular, almost glabrous above, densely floccose tomen- 

 tose beneath, not cordate, on petioles of equal or double length, 

 l)lade six lines long; loosely pilose at the nodes, branched above, 

 six inches high; pedicels and involucres glandular-hairy; pedicels 

 four to six lines long, usually erect or spreading, but lower ones 

 often reflexed (in rare cases all the pedicels are reflexed); involu- 

 cres fully a line long, rather deeply lobed and lobes deep blood- 

 red, hyaline-margined; flowers a line long, red with very deep 

 red midvein which stops short of the rounded, emarginate tip; 

 lobes oblong, glabrous. The prettiest of the Gayiysma group. 

 May 28, 1891, Dugway, Utah, on the open level places at 5000 

 feet altitude. It is also very common in eastern Nevada in 

 similar situations. 



Eriogomim bicolor n. sp. Matted csespitose forming mats one 

 to two feet in diameter from a very thick woody stem whose bark 

 exfoliates like Artemisia tridentata, one to three inches high; 

 whole plant tomentose to the glabrous perianth; leaves linear, 

 revolule, six to eight lines long; peduncles scapose, an inch 

 long, bearing a single rather large involucre or occasionally 

 three; bracts minute, green; involucre two lines high, turbinate, 

 not angled, eight-toothed and teeth short and hyaline; pedicel 

 two lines long, erect; flowers five to ten, a line long, base hemi-
