14. G. tricolor. 

 Lobes or teeth of leaves (exclusive of spines at tip) broader than long, the blades always 

 glandular ; seeds not mucilaginous when wetted ; trausmontane deserts. 

 Leaves oblanceolate or linear, dentately toothed or pirmately lobed; capsules usually well 



exceeding the calyx; corolla 2 to 3 lines long 15. G. leptomeria. 



Leaves orbicular to obovate, coarsely spiny-dentate or some (especially the lower) pin- 

 nately cleft and divided; corolla 3V^ to 5 lines long; capsules merely equaling 

 or shorter than calyx. 

 Stems leafy to middle or up to inflorescence ; stamens inserted at middle of corolla- 

 tube, exserted from corolla-throat 16. G. latifolia. 



Stems leafy only at base or sub-basally; stamens inserted near base of corolla-tube, 

 included in the corolla-tube 17. G. gilmanii. 



b. Inflorescence densely leafy, the leaves surpassing or equaling the flowers; transmontane deserts. 



Leaves mostly entire, the basal ones always so ; flowers both glomerate and solitary, the glomerules 



terminal, the lower flowers solitary 18. G. depressa. 



Leaves pinnatifid, especially the basal; flowers in dense terminal heads, none solitary 



19. G. polycladon. 

 S. Corollas campanulate or Uirbinate; desert species. 



Corolla cleft % or nearly % to base, white. 



Stamens inserted near base of corolla-tube; corolla 3 to 4 lines long, its throat yellowish 



20. G. campanulata. 



Stamens inserted in corolla-throat near sinuses; corolla 1% lines long, its throat whitish 



21. G. micromeria. 

 Corolla cleft nearly to base or at least % the way to base. 



Leaves ovate to oblanceolate, the basal ones largest; corolla white, the throat yellow 



22. G. itiyocnsis. 

 Leaves filiform, the upper ones equaling or longer than the lower; corolla yellow 



23. G. filiformis. 



II. Cells of capsule usually one-seeded (cf. also no. 21) ; cismontane and transmontane. 



Leaves all entire, mostly opposite; corolla salverform 24. G. gracilis. 



Leaves pinnatifid or trifid (rarely some entire), all alternate; corolla tubular-funnelform 



25. G. gilioidcs. 

 1. G. aggregata Spr. Scarlet Gill\. Skyrocket. (Fig. 379.) Stems 1 or 

 several from the perennial or biennial root-crown, erect and usually simple, 1 to 

 314 feet high ; herbage thinly puberulent or villous or glabrate, often slightly glan- 

 dular, the leaves beneath usually somewhat villous ; leaf-blades pinnately divided 

 into linear segments, the segments microscopically bristle-tipped, % to IV2 inches 

 long, rather remote or those of the basal leaves crowded; petioles 1/4 to 1^2 inches 

 long; flowers in an elongate thyrse; calyx 11/2 to 3 lines long, its lanceolate lobes 

 11/2 to 2 times as long as the tube; corolla salverform, commonly scarlet but varying
