314 COMPOSITE. Lagophylla. 



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

 crowded heads conspicuously and densely ciliate with very soft villous hairs, and b:ick occasion- 

 allv beset with sessile or short-stipitate glands: involucral bracis C'>mose-ciliate at tlie 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, carinate down the 

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

 Lagophylla, Nutt. 



L. ramosissima, NUTT. Sleuder, paniculatel\ r much branched, 6 to 30 inches high : leaves 

 entire ; radical and lowest cauliue obovate-spatulate ; upper 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 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 glomerules : akenes 2 lines long. Bull. Torr. Club, x. 87. Hemisonia conr/esta, 

 Gray in Pacif. 11. Rep. iv. 109 (immature), not DC. From Marin Co. to the Sierra Nevada 

 and to Mendocino Co., California, Bigc/ow, Torrey, Lemmon, Greene, Mrs. Ciirran. 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 Beecliey'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 ; 

 Gray, PL Fendl. 103, & Bot. Calif, i. 3G8. Madaroglossa & Oxyura, DC. Prodr.

 Beech. 356. Calliachyris, Torr. & Gray, in Bost. Jour. Nat. Hist. v. 110. 

 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. MADAEOGLOSSA, 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 conspicuous, 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. & ARN. 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 copious, the outer straight and erect, the inner soon crisped and interlaced into .1 

 woolly mass. Bot. Beech. 358; Torr. & Gray, I.e. L. Neo-Mexicana, Gray, PI. Wright, 

 ii. 98, a form with vestiges of pappus to ray-akenes. Blepharipappus glandulosws, 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, GRAY, Bot. Calif, i. 368, a rare state with rose-purple rays. Ojai, Cali- 

 fornia, Peckham, Palmer.
