76 POLEMONIACE2S. (&ILJA FAMILY.) 



Leaves various but never simply pinnate with entire leaflets Gilia. 1 



Leaves simply pinnate; leaflets linear to ovate; corolla short Polemonium. 2 



1. GILIA. Ruiz Pav. 



Corolla funnel-form, salver-form, or sometimes short-campanulate or rotate, regular. 

 A polymorphous genus, the sections having almost generic differences. 



SERIES I. Stamens attached to the corolla at unequal heights. 



Mostly viscid-pubescent or glandular; all but some of the lower leaves alternate; sta- 

 mens exserted. Gollomia. 



.SEUIES II. Stamens equally inserted, but sometimes with unequal filaments. 



* All of the leaves opposite, at least on the main stems, sessile and palmately parted or 



rarely entire. (Seeds mucilaginous in water. } 



Corolla from short funnel-form to almost rotate; the lobes obovate; filaments slender; 



anthers oval. Low or slender, loosely and mostly small flowered annuals; the leaves 



\vith filiform or setaceous divisions, appearing as if whorled. In ours, the flowers on 



filiform pedicels, loosely paniculate. 1. Dactylophyllum. 



Corolla salver-form, but the tube shorter than the calyx, the broad cuneate-obovate 



lobes slightly crenulate, strongly convolute in the bud; stamens inserted low on the 



corolla tube, included; erect, smooth; leaves entire or 3-5-divided. 2. Linanthus. 



Corolla salver-form, with usually a filiform elongated tube, and the throat sometimes 



abruptly dilated; stamens inserted in the throat; anthers short. Erect annuals, with 



leaves as in the last, and the flowers in a terminal capitate cluster. 3. Leptosiphon. 



* * All the, leaves alternate, and palmately parted. 



Corolla similar to 3. Stems woody; leaves much fascicled in the axils, 3-7 parted, 

 rigid; flowers sessile, solitary or few at the ends of short branches. 4. Leptodactijlon. 



* * * All, or all but the loivest leaves alternate and pinnately compound, deft or toothed, 



or rarely entire. 



Flowers capitate-glomerate or densely clustered, leafy-bracted; bracts and calyx-lobes 

 often laciniate, rigid acerose or spinulose-tipped. Corolla slender tubular-funnelforrn, 

 with small oblong lobes; cells of the ovary and stigmas sometimes only 2. Annuals, 

 mostly viscid-pubescent, never white-woolly, with once or twice pinnatifid leaves, their 

 lobes commonly pungent; the bracts sometimes palmately cleft. 5. Navarreiia. 



Flowers, inflorescence, etc., nearly as in 5; but the anthers always exserted; corolla 

 salver-form, more conspicuous; plants all white-woolly, not viscid. 6. Hucjelia. 



Flowers capitate-glomerate, or panicled, or scattered, usually bractless; corolla (blue,
