1904] EASTWOOD: WESTERN POLEMONIACEAE * 439 
pedicels short: calyx about equaling the corolla, more than 
7™m long, the segments triangular-acute, as long as the tube, 
veiny: corolla funnelform, with the divisions spreading, orbicular- 
obovate, erosely denticulate, 5™™ long and wide, purplish-blue: 
stamens shorter than the corolla, the attached part very woolly, 
longer than the free portion, the latter 2™™; anthers elliptical, 
2.33™™ long, obtuse at apex and obtusely sagittate at base: 
pistil with style and stigma extending slightly beyond the calyx, 
exserted but little from the bud; ovary suborbicular. 
This also comes in the aces under P. humtle Willd. and is near P. 
californicum. It is peculiar in having a much larger calyx, shorter stamens 
and style, and leaflets differently shaped. The type was collected near Cinder 
pee Mount Lassen, California, by Mrs. C. C. Bruce, July 1897. 
v Polemonium tricolor, sp. nov.—Stems 10-15 °™ high, apparently 
from running rootstocks; caudex clothed with broad chartaceous 
bases of old petioles; sparingly villous throughout with jointed 
hairs and glandular especially on the flowering stems: radi- 
cal leaves erect, the rachis and petiole margined, strongly 
ribbed through the middle, 1™™ wide; petioles 2-4°™ long, 
dilated for almost half the length, reddish; leaflets 11-17, 
obovate or elliptical, callous-mucronate at apex, oblique and 
cuneate at base, confluent with the rachis, lowest alternate, 
upper opposite; cauline shorter and with shorter and broader 
petioles, the leaflets fewer, longer, and narrower: flowers in close, 
erect, compound cymes; buds erect; pedicels and peduncles 
flat, margined, viscid, 1-5 ™™ long; bracts simple or 3—5-foliate: 
calyx open-campanulate, rounded at base, 5™™ long, the trian- 
gular-obtuse segments half the entire length, densely glandular 
on both sides: corolla rotate-campanulate, violet with a reddish- 
purple spot near the base of the divisions, throat yellow; 
divisions suborbicular, emarginate at apex, 6™™ long, 5.5™™ 
wide, almost twice as long as the included tube; this glandu- 
lar and ridged with the woolly adherent bases of the filaments: 
stamens with the free part of the filaments about 4™™ long; 
anthers white, elliptical, auriculate at base, obtuse, 1.5™™ long: 
ovary orbicular in outline; style not surpassing the calyx; 
stigmas 3-4, 3™™ long: capsule 3-valved, but not ripe in the 
type specimen.
