G. stricta. G. Amarella var. stricta Watson, Stem strict, 1-4 feet 
high, with strict branches, remotely ealyis leaves thickish, the cauline 
lanceolate-linear: flowers numerous, usually 4-merous: calyx deeply cleft, 
the lobes unequal: corolla whitish, 3-5 lines long, but little longer than 
the calyx: crown in the throat of few setae or wanting. Mountains of 
Idaho, Wyoming and Nevada. 
§ 2 PneumonanTHA Neck.. El. ii, 12. Flowers almost always 
5-merous. Corolla plicate at the sinuses, the pleats more or less 
extended into thin-membranaceous teeth or lobes: without crown 
or glands. Stigmas distinct. Capsule more or less stipitate. 
* Perennial by offsets or propagula :fleaves marginless: flowers cym- 
ose: calyx short, §-cleft: anthers oblong-linear, introrse, remaining 
erect. 
G. Douglasiana Bong. Veg. Sitka, 38, t, 6. Stem 2-10 inches high, 
cymosely branched: leaves ovate, the lowest rosulate, the cauline of few 
remote pairs and somewhat cordate, 2-4 lines long: corolla yellow, 4-6 
lines lony, its lobes obleng, shorter than the funnelform tube, not twice 
as long as the conspicuous and equally broad 2-cleft lobes in the sinuses: 
capsule stipitate, obovate, two-edged above: seeds elongated-oblong, a line 
long, apiculate at both ends; coat close. In wet places, Oregon to Alaska. 
* * Root perennial: flowers comparatively large, mostly short-ped- 
uncled or sessile, usually two-bracteate below : anthers linear, or oblong,

G. Newhberryi Gray Proc. Am. Acad. xi, 84. ‘ Stems 1-flowered, 2-4 
inches long, and ascending from the axils of the rosulate-radical leaves: 
these obovate or spatulate, an inch or more long; cauline leaves much 
smaller, connate-sheathing ; the lowest obovate, the uppermost lanceolate : 
calyx-lobes lanceolate or oblong, nearly the length of the oblong-campanu- 
late tube: corolla broadly funnelform, inch and a half long, pale blue, 
white within, greenish dotted; its lobes ovate, mucronate; the interposed 
- appendages 2-cleft or laciniate, subulate-tipped : seeds round-oval, smooth, 
broadly winged. Sierra Nevada, California, in or near the alpine region, 
from Mariposa Co. north to 8. Oregon. 
+ + Low: stems several from the same caudex: cauline leaves 6-16 
pairs, more or less connate or even sheathing at base, the uppermost 
involucrate around the sessile terminal flower or 3-5-flowered cluster. 
G. bisetwa. Stems decumbent or ascending, 8-16 inches long: leaves 
rather thick, oval to oblong, or the uppermost lanceolate, all rounded at 
the apex ; narrowed and connate-sheathing below, about an inch long, the 
uppermost pair close to the solitary flower: calyx-lobes lanceolate, acute, 
4-5 lines long by a line broad, about as long as the tube, strongly nerved: 
lobes of the blue corolla oblong, acute, not half as long as the campanu- 
late tube; appendages in the sinuses two setae from a rather broad base: 
capsules stipitate: seeds oblong, with a broad wing all around, usually 
widest on one side. In marshes, eastern base of the Coast Mountains 
near Waldo, Oregon. 
G. calycosa Griseb. Gent. 251. Stems erect, 6-12 inches high, leaves 
ovate, 6-15 lines long, commonly equalling or exceeding the internodes, 
the lowest pairs smaller and with connate-sheathing base, the upper hardly 
30; the uppermost involucrate and somewhat exceeding the calyx of the 
commonly solitary flower: lobes of the calyx ovate or oblong, or even sub- 
cordate, about as long as the turbinate tube: corolla oblong-funnelform, 
its appendages in the sinuses triangular-subulate, laciniate or 2-cleft at
