B14 COMPOSIT.E. Lagophylla. 



* * T\'pical species : leaves canescent with soft silky pubescence : the short ones subtending the 

 crowded heads conspicuously and densely' ciliate with verj' soft villous hairs, and bMck occasion- 

 allv beset with sessile or short-stipitate glands: involucral bracts cnniose-ciliate at the sides 

 (along the line of infolding) : ligules short, pale yellow according to Nuttall, but certainly some- 

 times if not always purplish or rose-color: akenes clavately obovate-oblong, cariuate down the 

 ventral face : stems at length becoming naked below by the early fall of the older leaves. — 

 Liiyophylla, Nutt. 



L. ramosissima, Nutt. Slender, paniculately much branched, 6 to 30 inches high : leaves 

 entire ; radical and lowest cauline obovate-spatulate ; upper lanceolate or linear, obtuse ; 

 uppermost liuear-obloug : heads 3 lines long, glomerate in small and at length rather scat- 

 tered irregular clusters : akenes only a line and a half long. — Trans. Am. Phil. Soc. vii. 

 390; Torr. & Grav, Fl. ii. 402; Gray, Bot. Calif, i. 367, mainly. L. minima, Kellogg, Proc. 

 Calif. Acad. v. 53. — Dry ground, common through California, and to Washington Terr., 

 Nevada, and W. Idaho ; first coll. by Nuttall. 



L. COngesta, Greene. Robust, a foot to a yard high, with short branches and larger heads 

 in thick ghjuierules : akenes 2 lines long. — Bidl. Torr. Club, x. 87. Hemitonia congesta, 

 Gray in Pacif. R. Rep. iv. 109 (immature), not DC. — From Marin Co. to the Sierra Nevada 

 and to Mendocino Co., California, Bigelow, Torreij, Lemmon, Greene, Mrs. Ciirran. Chaff of 

 receptacle not found to be " united into a cup " : perhaps only a gigautesque form of the 

 preceding species. 



127. LAYIA, Hook. & Arn. {Thomas Lay, naturalist in Beechey's Voy- 

 flge.) — Annuals, of California and adjacent parts ; with chiefly alternate leaves^ 

 and branches terminated by usually showy heads of flowers, in spring and early 

 summer : disk-corollas sparsely hispidulons or hirsute on the lobes, yellow : rays 

 yellow or white. — Bot. Beech. 148 & 357 (not 182) ; Torr. & Gray, Fl. ii. 393 ;

 Certain species are so much alike in their whole asjiect and structure that the 

 technical characters which alone distinguish them may be expected to give way. 



§ 1. Madaroglossa, Gray, PI. Fendl. 1. c. Pa2:)pus of about 10 to 20 stout 

 bristles, which are long-plumose or villous below the middle : akenes all narrow 

 and somewhat clavate, mostly with an obvious almost cupulate epigynous disk, 

 at least in the ray : receptacle naked and pubescent among the disk-flowers : 

 herbage hispid or hirsute, somewhat viscid, above beset with scattered stipitate 

 blackish glands. — Madaroglossa^ DC. 1. c. Layia, Hook. & Arn. 



* Rays bright white (sometimes tinged with rose), large and conspicuous, commonly half to three- 

 fourths inch long, 3-lobed : lower leaves lanceolate or linear, laciniate-pinnatilid or incised, 

 upper narrower and entire: pubescence more or less hispid or hirsute and with scattered short- 

 stipitate dark glands, especiall3' toward the heads: lobes of the disk-corollas with some sparse 

 hispid iiairs: pappus bright white. 



L. glandulosa, Hook. & Akn. a span to a foot or more high, diffusely branched : dark 

 glands sometimes abundant, sometimes scarce : rays 8 to 13 : villous hairs of the pajjpus- 

 bristles co])ious, the outer straight and erect, the inner soon crisped and interlaced into a 

 woolly mass. — Bot. Beech. 358 ; Torr. & Gray, I. c. L. Neo-Mexicana, Gray, PI. AYright. 

 ii. 98, a form with vestiges of pappus to ray-akenes. Blepharipappus t/Jandulosus, Hook. Fl. 

 i. 316. Eriopappus glandulosus, Arn. 1. c. Madaroglossa angustifolia, DC. Prodr. v. 694, ex 

 Hook. & Arn. — Barren ground, British Columbia to S. California and the Mexican border, 

 and east to Idaho and New Mexico. Variable, sometimes with stems almost glabrous, some- 

 times with hairs of the pappus less copious. 



Var. rosea, Gr.w, Bot. Calif, i. 368, a rare state with rose-purple rays. — Ojai, Cali- 

 fornia, Pcckham, Palmer.
