458 POLEMONIACE^ hugelia 



GILIA 



rather stout 6-8 inches high, very rigid, especially the leaves and bracts ; 

 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. Keg, 1652. 



Low floccose-lanate plants with narrow or narrowly lobed al 

 ternate leaves, and blue or white flowers in leafy-br acted terminal 

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

 ulate and cuspidate or pungent lobes. Corolla salverform; with 

 ovate or oblong lobes. Filaments filiform, exserted: anthers 

 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 lobee ; 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 GILTA 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 funnelform 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-celled 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 throughout : 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 

 mostly petioled, %-£ 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. aggregata Spreng. Syst. i, 626. Somewhat pubescent: stems erect, 

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

 isb, 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 or
