Gilia. POLEMONIACE^. 143 



§ 7. HuGELiA, Gray. Flowers capitate-glomerate and foliaceous-bracted : the 

 3-5-cleft bracts and calyx densely implexed-woolly ; lobes of the latter acerose 

 or subulate and cuspidate or pungent : corolla salverform ; the lobes ovate or 

 oblong : filaments filiform, exserted : anthers deeply sagittate : herbage floccose- 

 lanate, at least when young, neither glandular nor viscid : leaves or their simple 

 divisions very nari'ow and mostly rigid. — Hugelia, Benth. in Bot. Reg. 1. c. Gilia 

 § CoUomioides & § Pseudocollomia, EndL, Benth. in DC. 



* Woody-based and I'igid perennial: corolla violet-blue: ovules few or several in each cell. 

 G. densifolia, Benth. Cancscent-lanate when young, glabrate with age : tufted stems 

 a span to a foot or more high from a ligneous base, leafy to the top, simple or sparingly 

 branched : leaves rigid, mostly pinnatifid or incisely laciniate into short-subulate spinu- 

 lose lobes: flowers densely capitate-glomerate: tube of the corolla (half inch long) twice 

 or thrice the length of the calyx : anthers sagittate-linear. — DC. Prodr. ix. 311 ; Gray, 1. c. 

 {Ilmjelia densiflora, Benth. in Bot. Reg.), a short and stout form, with crowded leaves. G. 

 elongata, Steud. ; Benth. 1. c, a taller and looser form, with cells of the ovary usually only 

 2-8-ovuIate. — California near the coast, from Santa Clara Co. southward, and thence to 

 W. Arizona and S. Nevada. 

 * * Herbaceous, and the root annual or biennial : leaves or divisions nearly or quite filiform. 



•J— Corolla violet, blue, or purple, or fading to white : ovules few (but seldom if ever solitary) in 

 the cells. 



G. virgata, Steud. "White-floccose becoming glabrate : stem slender, either simple and 

 virgate (a span to a foot high) or with virgate branches from the base' and pauiculately 

 branched above : leaves slender-filiform ; the lower mainly entire and the upper rarely 

 more than 3-parted: flowers usually in rather small capitate clusters: corolla blue or lav- 

 ender ; the tube 4 to 6 lines long, surpassing the acerose caly.x-lobes : anthers linear-sagit- 

 tate, a line long. — [Ini/clia vin/ata, Benth. 1. c. ; Hook. Ic. t. 200. — California, on dry hills 

 from Monterey soutliward, and east to Arizona. 



Var. floribunda, Gray. A remarkable form, with corymbose branches terminated 

 by much larger and very many-flowered capitate clusters : most of the leaves (even the 

 lower) pinnately 3-7-parted: corolla-lobes 3 or 4 lines long. — Proc. Am. Acad. 1. c, & Bot. 

 Calif, i. 495. — Santa Clara Co. to San Diego Co., Wallace, Breiver, Palmer. 



G. floccosa, Gray, More branched and generally lower than the foregoing, 2 to 12 

 inches high, similarly floccose-woolly, at length diffuse or spreading : corolla from violet- 

 blue to whitish ; its tube 3 or 4 lines long, surpassing the subulate calyx-lobes : anthers 

 narrowly oltlong, fully half a line long. — Proc. Am. Acad. 1. c. & Bot. Calif, i. 495, excl. 

 syn. " Hiif/r'Ha lutm, Benth." — Drv plains and desert, southern and eastern portions of Cali- 

 fornia and S. E. Oregon to Utah and Arizona. 



G. filif olia, Nutt. Flowers smaller ; the lobes of the corolla seldom over a line in length, 

 and its tube hardly if at all exceeding the calyx and bracts : anthers cordate-oval, a quar- 

 ter or third of a line long: otherwise like small forms of the preceding. — PI. Gamb. 156; 

 Gray, 1. c. — Santa Barbara and San Isabel, California, to the Rio Colorado. 



Var. diffusa, Gray, 1. c. A diffuse form, barely a span high ; the leaves commonly 

 rather shorter and less slender. — Interior of Nevada and Arizona to the western frontier 

 of Texas. 



H^ -!— Corolla yellow : ovules solitary in the cells. 



G. lutescens, Steud. A span high, closely resembles G. floccosa except in the above 

 particulars, and the bright sulphur-yellow corolla only 3 lines long ; its tube not exserted 

 and lobes hardly exceeding a line in length : anthers elongated-oblong : capsule oval, 3- 

 seeded. —- Benth. in DC. 1. c. 311. Hiifjclia litfm, Benth. in Bot. Reg. 1. c. — W. California; 

 back of Monterey ? Dour/las. Back of San Simeon, Palmer, confirming the yellow color of 

 the corolla. 



§ 8. Elaphocera, Nutt. Flow^ers capitate-congested or sometimes more 

 loosely cymose, more or less foliaceous-bracted : bracts and calyx-lobes commonly 

 cuspidate or aristulatc (but not pungent), and pubescent or ciliate vpith long and 

 many-jointed somewhat viscid hairs : corolla (white or barely purplish) salver-
