314 COMPOSITE. Lagophylla. 



* * Typical species : leaves canesccnt with soft silky pubescence : the short ones subtending the 

 crowded heads conspicuously and densely ciliate with very soft villous hairs, and b>iclt occasion- 

 ally beset with sessile or s"liort-stipitate glands : involucral bracts cmnose-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: alienes clavately obovate-oblong, carinate down the 

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

 Lagophylla, Nutt. 



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

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

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

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

 390; Torr. & Gra;y, Fl. ii. 402; Gray, Bot. Calif. 1. 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. Eobast, a foot to a yard high, with short branches and larger heads 

 in thick glomerules: akenes 2 lines long. — Bull. Torr. Club, x. 87. Hemizonia eonrjesta, 

 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. Curran. Chaff of 

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

 preceding species. 



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

 age.) — 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 hispidulous 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 aspect and structure that the 

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



§ 1. MAbAROGLOSSA, Gray, PI. Fendl. 1. c. Pappus 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 ccmspicuous, commonly half to three- 

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

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

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

 hispid hairs: pappus bright white. 



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

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

 bristles cojjicjus, the outer stniight and erect, the inner soon crisped and interlaced into a 

 woolly mass. — Bot. Beech. 358; Torr. & Gray, 1. c. L. Xro-Mrximiia, Gray, PI. Wright, 

 ii. 98, a form with vestiges of pappus to ray-akenes. BlepJiaripappiis iilnmiiiloxiis, Hook. Fl. 

 i. 316. Eriujiiiiijiiis gliiiidulosus, Arn. 1. c. Mtidardijhisisit angustifolia, DC. Prodr. .. 694, ex 

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

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

 times with hairs of the jjappus less c<3pious. 



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

 fornia, I'rrkhum, Palmer.
