Gilia. POLEMONIACE.E. 495 



dilated apex, more or less incised, all the teeth or lobes and here and there the even 

 margins beset with very long white bristles, many of the lower in pairs : calyx-lobes 

 similarly setose-tipped : corolla purple or purplish, 6 to 9 lines long : ovules several 

 or rarely few in each cell. Navarretia setosissima, Torr. & Gray, in Ives Colorado 

 Exp. 22. iV. Schottii, Torr. Bot. Mex. Bound. 145, a small form. 



Gravelly plains, on the Rio Colorado and the Mohave, and Providence Mountains {Coulter, 

 Newbcrry, Cooper, &c.), extending to Southern Utah. 



7. Flowers, inflorescence, &c., nearly as in the foregoing section ; but the anthers 

 longer and always exserted : corolla (salverform) more conspicuous : plants all 

 white with floccose wool, at least ivhen young, and neither glandular nor viscid. 

 HUGELIA (Hugelia, Benth. in Bot. Reg. Gilia Hugelia & Pseudocol- 

 lomia, Benth. in DC.). 



* Root perennial : stems ivoody at the base : anthers linear-sagittate : ovules several. 



28. G. densifolia, Benth. A foot or two in height : stems virgate from a woody 

 base, leafy to the top : leaves rigid, linear, laciniate-pinnatih'd or incised ; the short 

 lobes few or several, subulate : flowers numerous in a compact head : corolla over 

 half an inch in length, violet-blue, two or three times the length of the calyx (the 

 lobes 3 lines long) : anthers linear. Hugelia densifolia (a short stout form) and 

 //. elongata, Benth. 



Dry hills, from Santa Clara Co. to the Mohave, and in Southern Nevada. 



* * Root annual : stems slender, at length loosely branched, a foot or less in height : 

 leaves and their few (if any) divisions filiform : flowers rather few in the small 

 clusters. 



29. Gr. virgata, Steudel. At first strict and simple-stemmed, at length branched 

 from the base or throughout, sometimes glabrate : tube of the blue corolla longer 

 than the calyx : anthers (when dry) linear, deeply sagittate, a line long : ovules 2 to 

 5 in each cell. Hugelia virgata, Benth. ; Hook. Ic. PI. t. 200. 



Var. floribunda, Gray, 1. c. Low and rather stout : even the upper leaves 

 pinnately 3 - 7-parted : the numerous heads and flowers fully as large as those of 

 G. densifolia. 



Dry hills, Monterey to San Diego and east to the Rio Colorado. The remarkable variety from 

 Santa Clara Co. (Brewer) to Tejon, Wallace. 



30. Gr. floccosa, Gray, 1. c. Smaller than the preceding : leaves mostly entire : 

 corolla about 4 lines long, blue or becoming white (probably never " yellow ") : 

 anthers linear-oblong (barely half a line in length) : ovules 1 to 4 in each cell. 

 Hugelia lutea, Benth. in Bot. Reg. Gilia lutescens, Steudel ; Benth. in DC. (But 

 the flowers were doubtless bluish, faded to dull white.) 



Eastern borders of the State, from the Mohave to the Truckee, &c., and east to Utah. Also 

 near Monterey. 



31. Gr. filifolia, Xutt. Like the preceding, but more rigid : leaves mostly 

 3-parted : corolla blue or bluish, little if at all exserted : anthers oval, very small : 

 ovules 4 to 6 in each cell. PI. Gamb. 156 ; Gray, 1. c. 



Near Santa Barbara (NiMall), and San Isabel (Thurber), to the Mohave (Cooper), Arizona, 

 and Nevada. This and the preceding probably run together, and all these annual species are hard 

 to distinguish. 



8. Flowers capitate-crowded or somewhat looser, bracteate : corolla white or pur- 

 plish, salverform, mostly with a short tube : stamens shorter than the lobes of 

 the corolla, inserted in or near the sinuses : anthers short : lobes of the calyx 

 and of the leaves tipped with an awn-like bid not pungent cusp : low biennials, 

 annuals, or short-lived perennials, usually viscid-pubescent with many-jointed 

 hairs, and with simply pinnatiftd or entire leaves. ELAPHOCERA, Nutt.
