SOME WESTERN POLEMONIACEEX. 305 
I have been shown, by Mr. Coville, specimens of a third 
member of this genus, collected by himself, if I remember 
rightly, in Idaho, or eastern Washington. This is inter- 
mediate in size between the two better-known species, and 
remarkable for being constantly, and I believe, somewhat 
dichotomously branched; the flowers not as large as in 
G. pulchella, yet large enough to be rather showy. 
POLEMONIUM ELEGANS. Near P. viscosum, of the same 
habit, with similarly crowded small leaflets, but these 
obovate or spatulate-obovate rather than rounded, even 
more viscid than P. viscoswm, the inflorescence more ap- 
proaching the cymose: calyx narrow—campanulate rather 
than tubular, cleft to the middle, the segments ovate-oblong, 
obtuse; the corolla broad-funnelform, the gradually dilated 
tube yellow outside the calyx and about as long as the 
obovate blue segments; stamens included. 
In volcanic sand at 9000 feet altitade on Mt. Rainier, 
Washington, Aug., 1895, C. V. Piper; also on Mt. Paddo, 
Suksdorf. A beautiful species, and, with the next, conjoin- 
ing two rather different groups. 
POLEMONIUM EXIMIUM. Near the preceding, larger, less 
leafy, the leaflets extremely reduced in size, 3 to 5-parted : 
inflorescence quite as distinctly branched and capitate. 
cymulose: calyx more narrowly campanulate, with com- 
paratively shorter rather broadly oblong obtuse lobes: 
corolla not two-colored but wholly purple, the tube out- 
side the calyx cylindric rather than funnelform ; stamens 
shorter, even included within the tube of the corolla. 
I suppose that all the so-called P. confertum of the Cali- 
fornian Sierra is of this very distinct species. My speci- 
. mens are from an altitude of 12,300 feet on Mt. Conness, 
collected by Harford.
