der, anthers short, oblong or oval : ovules numerous in the cells : seeds 

 developing mucilage and spiral threads when wetted. On dry ridges in 

 mountainous districts, California to Brit. Columbia and Nebraska. 



* * * Flowers scattered, crowded or rarely capitate-glomerate> in- 

 conspicuously bracted or ebractate. 



■*" Ovules and seeds few or numerous in the cells : stamens insert- 

 ed in or j ust below the sinuses : annuals. 



** Corolla more or less funnelform, having a distinct tube. 



= Leaves once or twice pinnately parted or cleft: seeds developing 

 mucilage and spiral threads when wetted. 



G. capitata Dougl. Hook. Bot. Mag. t. 2698. Nearly glabrous: stem 

 rather slender, usually 1-3 feet high, paniculately branched : leaves 2-3- 

 pinnately divided into slender or even filiform lobes : flowers numerous, in 

 dense capitate clusters terminating long naked peduncles : calyx glabrous 

 or nearly so, the lanceolate acuminate lobes not longer than the campanu- 

 late tube : corolla blue to white, 4-5 lines long ; its tube about as long as 

 the narrowly oblong or lanceolate-linear lobes: stamens inserted in the 

 very sinuses of the corolla and equalling its lobes : anthers elliptical. Com- 

 mon in open places and fields, California to Brit. Columbia. 



G. achilleaefolia Benth. Bot. Reg. 1632. Somewhat pubescent: stem 

 rather stout, 1-2 feet high, loosely branched above : leaves once or twice 

 pinnately parted into linear ilobes : flowers numerous, in dense capitate 

 clusters terminating long peduncles : calyx pubescent ; its ovate almost 

 spinose-tipped lobes longer than the tube: lobes of the blue corolla obo- 

 vate or broadly oblong ; its throat abruptly and amply dilated : stamens 

 inserted in the sinuses of the corolla and about equalling its lobes. West- 

 ern California and Oregon to Brit. Columbia. 



G. inconspicua Dougl. Hook. Bot. Mag. t. 3883. Viscid, and usually 

 with slight woolly pubescence when young : stem stoutish, 4-13 inches high, 

 branching from the base : leaves mostly pinnatifid or pinnately parted, or 

 the lowest bipinnatifid with short cuspidate lobes, the upper becoming 

 small, subulate and entire : flowers somewhat crowded and subsessile, or 

 at length loosely panicled and some of them slender-pediceled : calyx 2 

 lines long,, the short subulate teeth not half as long as the tube: corolla 

 narrowly funnelform, with proper tube shorter or slightly longer than 

 the calyx : seeds several in each cell. Dry hillsides and sandy plains, Cali- 

 fornia and eastern Oregon to Brit. Columbia and the Rocky Mountains. 



Var. sinuata Gray Proc. Am. Acad, viii, 278. Corolla becoming thrice 

 the length of the calyx, with the tube more exserted, with the throat and 

 lobes more ample. Dry plains eastern Oregon to California and N. Mex. 

 = = Seeds destitute of mucilage and spiral threads when wetted. 



G. gracilis Hook. Bot. Mag. t. 3924. Stem stout, simple, or at length 

 corymbosely much branched and spreading, 2-10 inches high: leaves linear 

 or the lower ones obovate to lanceolate, entire, sessile, the lower ones 

 mostly opposite, 4-10 lines long: calyx rounded at base, deeply cleft, with 

 strongly carinate subulate lobes : corolla about 5 lines long, purple or vio- 

 let, the slender tube yellowish, and seldom longer than the calyx: seeds 

 flat and somewhat winged. Common in open places, Brit. Columbia to 

 California and Nebraska. 



G. leptomeria Gray 1. c. Somewhat glandular viscid : stem 6-12 inches 

 high : leaves mainly radical, oblong or broadly lanceolate, incisely toothed 

 or sinuate-pinnatifid the obtuse teeth or lobes minutely cuspidate ; the cau- 

 line small and reduced upward to the subulate bracts of the open effuse 

 cymose panicle ; flowers inconspicuous ; corolla white, 2-3 lines long, fully
