Flora of the Palousc Region \\i 



leaves narrowly-linear, sharp-pointed, 2-3 cm. long: flowers in loose cymes, 

 erect; pedicels 1-3 cm. long: calyx-tube somewhat angled, exceeded by the 

 subulate teeth: corolla pink-purple, the tube longer than the calyx; lobes 

 obovate, entire, 8-12 cm. long: style slender, as long as the corolla-tube. 

 Bluffs of .Snake River, variable. 



P. speciosa Dougl. Perennial, wood}- at base, the erect branches 10-40 

 cm. high, glabrous or nearly so, glandular-pubescent above: leaves linear, 

 attenuate from the base, 2-5 cm. long, the margins white, thickened: cymes 

 loose, the pedicels 1-3 cm. long: calyx-lobes subulate, not as long as the 

 tube: corolla pink, its tube exceeding the calyx; lobes obcordate, 8-14 mm. 

 long: style very short, not longer than the ovary or stigmas. 



var. sabinii Gray. Corolla-lobes entire. Common in moist ground, the 

 variety rather rare. 



234. GILIA. 



Herbs or suffruteseent plants: leaves alternate or opposite: calyx 

 narrow, the lobes acute, the tube scarious below the sinuses: cor- 

 olla tubular-funnelform, the limb little spreading (in ours): 

 stamens equally or unequally inserted: capsule with i-many 

 seeds. 



Leaves entire: flowers in heads. 



Flowers salmon-colored. 



Flowers pink. 

 Leaves entire: flowers solitary or in loose leafy cymes. 



.Stems simple below: flowers 8-10 cm. long. 



Stems branched from the base: flowers 5-7 cm. long. 

 Leaves opposite, 3-7-palmately parted into linear lobes. 

 Leaves alternate, pinnately parted into narrow lobes. 



Flowers very small, bluish. 



Flowers large, scarlet. 



G. grandiflora Gray. Frect, usually simple, 30-40 cm. high, viscid- 

 glandular below: leaves sessile, all alternate, lanceolate or linear, the upper 

 broader, all entire, 2-6 cm. long: flowers crowded in a terminal head-like 

 cluster: calyx obconical, the lobes broad, obtuse, shorter than the tube: 

 corolla salmon-color, narrowly funnel form, 1.5-2.5 cm. long: stamens un- 

 equally inserted: ovules and seeds solitary in the cells, the seed-coats devel- 

 oping spiricles when wetted. 



var. diffusa Mulford. Usually taller, 40-60 cm. high, the flowers in sev- 

 eral to many racemosely arranged smaller heads. The variety is very common 

 in stony soil, but the species is rare in our limits. 



G. linearis Nutt. Erect, simple or branched above, 10-30 cm. high, pub- 

 escent throughout, or glabrous below, glandular above: leaves sessile, alter- 

 nate, linear or lanceolate, acute, entire, 2-6 cm. long: flowers crowded in 

 head-like clusters: calyx-lobes triangular, acute, as long as the obconic tube: 

 corolla pink, 8-10 mm. long, slender-tubular, the lobes small: stamens un- 

 equally inserted: ovules and seeds solitary in each cell: seed-coats with 

 spiricles. Low ground, quite common. 



G. gracilis Hook. Erect, usually simple, 10-30 cm. high, branched 

 above, glabrous below, pubescent and glandular above: leaves sessile, entire.
