 northern Mojave Desert in Kern and north- 

 western San Bernardino Counties, California. 

 15b. G. latiflora speciosa. 

 Inflorescence loose-paniculate not subglomerate, the 

 branches slender, virgate; corolla 12-25 mm. 

 long with tube 0.5-0.7 mm. broad and lobes 

 2-3.9 mm. broad; southern Sierra Nevada in 

 Tulare County. 



15c. G. latiflora Purpustt.

15e. G. latiflora leptantha. 



Stamens equal or subequal, all shorter than the corolla-lobes. 



Corolla-tube shorter than corolla-throat. 



ISf. G. latiflora exilis. 



Corolla-tube longer than corolla-throat. 



16. G. siniiata. 



Basal leaves coarsely pubescent either with white geniculate hairs, translucent 

 straight hairs, or short gland-tipped hairs, never glabrous or woolly. 

 Basal leaves coarsely pubescent with white geniculate hairs or translucent 

 straight hairs, bi- to tripinnately lobed or toothed with slender rachis, 

 or leaves broad and irregularly cleft. 

 Calyx well-exceeded by mature capsule, glabrous, or occasionally very 

 1 lightly glandular-dotted; capsule oblong; uppermost cauline leaves 



usually entire. 

 Stamens less than 3 mm. long, shorter than the corolla-lobes; corolla 

 14-37 mm. long (except in subsp. australis). 



17. G. splendcns. 



Stamens 3-5.5 mm. long, longer than the corolla-lobes; corolla 7.5- 

 12.5 mm. long. 18. G. cartiifoha. 



Calyx accrescent, subequal to or exceeding the mature capsule, densely 

 glandular-dotted; capsule broadly ovoid; uppermost leaves toothed 

 or lobed, not entire. 

 Corolla-tube included in calyx, and from shorter than to less than 

 twice as long as throat; pubescence of lower leaves consisting 

 of white, geniculate hairs. 19. G. stellata. 



Corolla-tube elongate, much exceeding calyx and more than twice as 

 long as throat; pubescence of lower leaves consisting of 

 straight (not geniculate), translucent hairs. 



20. G. scopnlorum. 



Basal leaves pubescent with short, gland-tipped hairs, shallowly sinuate- 

 toothed or short-lobed, the teeth acuminate or apiculate and tipped 

 with a sharp cusp; in the subspecies the lobes more deeply cut, rounded 

 and often with short secondary lobes. 21. G. leptomeria. 

 Flowers usually solitary in the leaf-axils; leaves typically entire or filiform, sometimes the lower 

 pinnately dissected into filiform segments. 

 Stamens unequally inserted on the corolla throat; corolla-lobes a rich pink or rose; corolla 



7-20 mm. long. _ 22. G. Icptalea. 



Stamens equally inserted; corolla-lobes pale pink, white or light blue. 



Ovules 1 to each locule; stamens inserted on corolla-tube. 23. G. minutiflora. 



Ovules several to each locule, stamens inserted in sinuses of corolla-lobes 



24. (j. captilaris. 



Corolla campanulate or turbinate; flowers usually solitary in the leaf-axils or on the stem opposite a leaf. 



Corolla 1-2 mm. long or less, barely exserted from the calyx, usually turbinate. 



25. G. tenerrima. 



Corolla 2-5 mm. long, 2 or more times the calyx. 



Corolla golden yellow; leaves linear-filiform. 26. G. filiformis. 



Corolla white or cream, the throat yellow ; leaves, at least the lower, ovate to ovate-lanceolate. 



Corolla-tube and throat shorter than the calyx as well as shorter than corolla-lobes; stamens 

 equal, 27. G.inyoensis. 



Corolla-tube and throat longer than the calyx and longer than the corolla-lobes; stamens 

 unequal. 28. G. campanulata.
