G. stricta. G. Amarella var. stricta Watson, Stem strict, 1-4 feet 

 high, with strict branches, remotely leafy: 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: 4 leaves marginless: flowers cym- 

 ose: calyx short, 5-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 Ion*, its lobes oblong, shorter than the funnelform tube, not twice 

 as long as the conspicuous and equally broad 2-clef t 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, 

 unconnected, seldom connivent, more or less extrorse, remaining erect. 



-- Dwarf ; 1-5-flowered : cauline leaves only 2-4 pairs. 



G. Kewberryi 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 S. 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. bisetaea. 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 

 so; 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
