GILIA 



these lanceolate or the uppermost ones ovate, all pinnatifid and with diva,- 

 ricate subulate-spinose lobes : flowers glomerate : calyx cylindraceous with 

 unequal, entire or 3-cleft, pungent teeth : corolla purple, about twice the 

 length of the calyx; ovules 6 or 7 in each cell. On dry ridges, southwest 

 Oregon to California. ' 



6 HUGELIA Benth. Bot. Reg. 1652. 

 Low floccose-lanate plants with narrow or narrowly lobed al- 

 ternate leaves arid blue or white flowers in leafy-bracted terminal 

 glomerules. Calyx densely woolly, 4-5-lobed, with acerose ' or 

 subulate and cuspidate or pungent lobes. Corolla salverf orm ; 

 with ovate or oblong lobes. Filaments filiform, exserted: an- 

 thers deeply sagittate. Seeds few in each cell. 



H. floccosa. Gilia floccosa Gray. Floccose-woolly, at least when 

 young: stem 2-12 inches high, simple or branched, often diffuse or spread- 

 ing : lobes of the calyx subulate, unequal, one large and three smaller ones, 

 pungent : corolla yellow with blue or white lobes ; its tube 3-4 lines long, 

 surpassing the calyx-lobes: anthers narrowly oblong: seeds 1 or 2 in each 

 cell. Dry plains, southeastern Oregon to California, Utah and Arizona. 



7 GILIA Ruiz & Pav. Prodr. Fl. Per. & Chil. 25, t. 4. 



Herbs with alternate or opposite simple or compound leaves 

 and various inflorescence. Calyx campanulate or tubular, 5- 

 tOothed or 5-cleft, the sinuses usually scarious. Corolla funnel- 

 form or salverform, or sometimes campanulate or nearly rotate, 

 regular. Stamens equally or unequally inserted in the tube or in 

 the throat of the corolla : the mostly slender filaments sometimes 

 unequal in length. Ovary oblong or ovoid, 3-jcelled with solitary 

 or several ovules in each cell. Seeds 1-10 in each cell, usually 

 developing mucilage, and often spiral threads, when wetted. 



* Bracts and calyx-lobes commonly cuspidate or aristulate, and 

 pubescent with long and many-jointed somewhat viscid hairs: flowers 

 capitate-congested or sometimes more loosely cymose. 



G. congesta Hook. Fl. ii, 75. White-pubescent throughput: root per- 

 ennial : stems erect or spreading, 3-12 inches long from a tufted base, 

 bearing simple terminal or few and corymbose capitate cymes: leaves 

 inostly petioled, %-2 inches long, pinnately divided into 3-9 narrowly 

 linear mucronate divisions, or the uppermost entire: calyx campanulate; 

 with very short tube and oblong cuspidate-pointed lobes: corolla white, 

 with oval lobes nearly as long as the tube, which does not exceed the 

 calyx'-lobes : filaments short, at length as long as the anthers : ovules 1-4 

 in each cell. Dry plains, eastern Oregon to California and Nebraska. 



* * Rather tall biennials with thyrsoid-paniculate inflorescence. 



G. aggregate Spreng. Syst. i, 626. Somewhat pubescent: stems erect,. 

 1-4 feet high, leafy, simple, or sometimes loosely branched : leaves thick- 

 ish, 1-3 inches long, mostly petioled, pinnately parted into narrowly linear 

 mucronulate segments : flowers in a thyrsoid narrow loose or interrupted 

 panicle, sessile, in small mostly short-peduncled clusters : calyx commonly 

 glandular, 3-4 lines long ; the campanulate tube about as long as the subu- 

 late teeth : corolla from scarlet to pink or white, 12-18 lines long, tubular- 

 funnelform; its lobes ovate or lanceolate, acute or acuminate, 3-4 lines 

 long, widely spreading, soon recurved : stamens inserted in the throat r- 

 below the sinuses of the corolla, not longer than its lobes; filaments s'^:;
