198 POLEMONIACEAE. 



bracted; calyx narrow, 5-cleft; corolla salverform with a long 

 tube, a narrow opening and broad or rounded lobes; stamens 

 included, very unequally inserted on the upper part of the corolla- 

 tube; ovules 1 or sometimes 2; capsules ovoid, with but one 

 seed in each cell. 



Densely tufted with crowded leaves; flowers solitary on the 



shoots. P. rigida. 



Loosely tufted and taller; flowers in cymes. 



Style short, not longer than the ovary. P. speciosa. 



Style long, usually equalling the corolla tube. 



Inflorescence not glandular; leaves 1 mm. wide. P. longifolia. 



Inflorescence glandular; leaves 2-4 mm. wide. P. viscida. 



Phlox rigida Benth. (P. piperi E. Nelson.) Perennial from a woody much 

 branched base; leafy stems erect or ascending, 10-20 cm. high, sparsely gland- 

 ular-pubescent throughout; leaves spreading, acerose, sharp-pointed, 10-15 

 mm. long; flowers solitary on short peduncles; calyx hirsute, the teeth rigid, 

 subulate, sharp-pointed; corolla pale bluish, the tube hairy at base within, 

 nearly twice as long as the calyx, the lobes cuneate-obovate, 6-9 mm. long. 

 Common in pine woods about Spokane, and in the Blue Mountains. 



Phlox speciosa Pursh. Perennial, woody at base, the erect branches 10-40 

 cm. high, glandular-pubescent above becoming glabrous or nearly so toward 

 the base; leaves linear, attenuate from the base, 2-S 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 ob- 

 cordate, 8-14 mm. long; style very short, not longer than the ovary or stigmas. 

 Common in moist ground. 



Phlox speciosa elatior Hook. Corolla-lobes entire. In moist ground, 

 rather rare. Apparently a mere form. 



Phlox longifolia Nutt. Perennial, woody and loosely branched at base, 

 the branches erect or nearly so, 10-30 cm. high, glabrous or puberulent; 

 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 mm. long; style slender, as long as the corolla-tube. 

 In the warmer valleys, variable. 



Phlox viscida E. Nelson. Perennial; stems erect, 10-15 cm. high; herbage 

 green, viscid-pubescent throughout, more dense on the pedicels and calyx; 

 leaves linear or lance-linear, rather rigid, sharp-pointed, 2-4 cm. long; calyx 

 13 mm. long, the lobes subulate, as long as the tube; corolla pinkish, the tube 

 slightly longer than the calyx, the lobes obovate, finely erose; ovules solitary 

 in each cell. Blue Mountains. 



292. GILIA. 



Herbs or half -shrubby plants; leaves alternate or opposite; 

 calyx narrow, the lobes acute, the tube scarious below the sinuses; 

 corolla tubular-funnelform, the limb little spreading (in ours); 

 stamens equally or unequally inserted; capsules with 1-many 

 seeds.
