sepals. The insertion of the two pairs of stamens unequally is, 
so far as my field studies 8° 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. 
LPentstemon deustus, 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. 
Eriogonum rubiflorum n. sp. Near E. rentforme but leaves 
oval to orbicular, almost glabrous above, densely floccose tomen- 
tose beneath, not cordate, on petioles of equal or double length, 
blade 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 
ted midvein which stops short of the rounded, emarginate tip; 
lobes oblong, glabrous. The prettiest of the Ganysma 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. 
Eriogonum bicolor n. sp. Matted ceespitose forming mats one 
to two feet in diameter from a very thick woody stem whose bark 
exfoliates like Artemzsia tridentata, one to three inches high; 
whole plant tomentose to the glabrous perianth; leaves linear, 
revolute, 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-
