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

 3-5-cleft bracts and calyx densely implexed-vvooUy ; 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

 § Collomiuidcs & § PseuducuUoinia, Endl., Benth. in DC. 



* VVoodj'-based and rig-id peruiiiiiai : corolla violet-blue: ovules few or several in each cell. 

 G. densifolia, Benth. Canesccnt-lcan.ate when young, glabnito with age : tufted stems 

 a span to a foot or more high from a, ligneous base, leafy to the top, simi:)le or sparingly 

 brancheil : 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. Trodr. ix. 311 ; Gray, 1. c. 

 {HurjeUa densijbUa, Benth. in Bot. lieg.), a short and stout form, with crowded leaves. G. 

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

 2-3-ovulate. — 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. 



•(— Coi-olla violet, blue, or purple, or fading to wiiite : ovules few (but .seldom if ever solitary) in 

 the cells. 



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

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

 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 calyx-lobes : anthers linear-sagit- 

 tate, a line long. — ILujdia vini<Lta, Benth. 1. c. ; Hook. Ic. t. 200. — California, on dry hills 

 from Monterey southward, and east to Arizona. 



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

 by much larger and very jnauy-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., Wdllace, Brewer, Palmer. 



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

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

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

 syn. " Hmjelia hitea, Benth." — Dry plains and desert, southern and eastern portions of Cali- 

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



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

 and its tube hardly if at all exceeding tlie 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 higii ; 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. lutsscens, Steud. A span high, closely resembles G. floccosa except in tlie 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: ca])sule oval, 3- 

 sceded. — Benth. in DC. 1. c. 311. UiKjelia liitea, Benth. in Bot. lleg. 1. c. — W. California;
