. POLEMONIACKE. (GILIA FAMILY.) 77 



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. Leptodactylon. 



* * * All, or all but the lowest leaves alternate and pinnately compound, cleft 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-funnelform, 

 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. Navarretia. 



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

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



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

 purple or violet) from funnel-form to campanulate or almost rotate; stamens included or 

 not surpassing the corolla lobes; leaves mostly pinnately incised. 7. Eugilia. 



1. Dactylophyllum. Benth. 



1. G. liniflora, Benth. From a few inches to over a foot high; leaves with nearly 

 filiform divisions an inch long; corolla white, rotate, when fully open, 10 to 6 lines across, 

 5-parted down to the very short tube. 



Var. plaarnaceoides, Gr., is similar but smaller; the (sometimes pinkish) corolla half 

 an inch across, or less. 



2. G. pusilla, Benth. Small, 2 to 6 inches high; leaves less than half an inch long, 

 shorter than the scattered pedicels; corolla nearly white, or purplish with a yellow 

 throat, \\ to 2 lines long, little exceeding the calyx. 



Var. Californica, Gr., has a corolla 3 lines long, twice the length of the calyx; the 

 throat often brownish. The most frequent form. 



3. G. Bolanderi, Gr. Very like the last, but the tube of the blue or purple tinged 

 corolla longer and narrower (3 or 4 lines long). 



4. G. aurea, Nutt. Diffuse, 2 to 4 inches high; divisions of roughish leaves nar- 

 rowly linear, 3 lines long; peduncles shorter or but little longer than the flowers; corolla 

 usually yellow, short, funnel-form half an inch or less across; the roundish-obovate lobes 

 about the length of the obconical throat and the sljprt proper tube.
