§ 3. Calliglossa, Gray, ]. c. Pappus wanting or of few or several flattened 

 awns or paleas (instead of bristles), either naked or with long hairs only at base. 

 — Calliglossa, Hook. & Arn., with Oxyiira, DC. & Lindl. 



* Ravs pure "white: only marginal receptacular bracts present: pappus aristiform: habit of Z-. 

 ylandulosa: a few small stipitate glands on the upper leaves and involucre. 



L. Douglasii, Hook. & Arn. Low, sparingly hirsute or hispid : radical leaves pinnatifid- 

 deutate ; upper linear and entire : rays rather short, broad, 3-cleft : lobes of disk-curolla hir- 

 sute outside : akenes narrow, those of the disk \ illous-pubescent : pappus of about 10 minutely 

 ■scabrous linear-subulate flat palese, nearly equalling disk-corolla; tlieir margins toward the 

 base scantily beset with long and straight villous hairs. — Bot. Beech. 358 ; Gray, Proc. Am. 

 Acad. ix. 194. — Gravelly banks, between the Dalles and Great Falls of the Columbia 

 Eiver, Dour/las (the pappus in the specimen fulvous by discoloration) ; Austin, Nevada, 1882, 

 i1/. E. Jones (pappus bright white). Probably only a form of L. ylandulosa with more 

 paleaceous and almost naked pappus. 



* * Rays yellow at base, white or pale at summit: bracts of the involucre lanate-ciliate at the 

 basal margins where infolded around the akene: both ray- and disk -akenes mostly oblong- 

 obovate. 



H— Pappus of 7 to 12 broadish naked palese: disk-akenes more or less villous-hirsute. — Calli- 

 achyrls, Torr. & Gray. 



L. Jonesii, Gray. Somewhat hispidulous and viscid, a few small and sessile dark glands 

 on and near the involucre: leaves hispidulous-ciliate, narrowly linear, simply pinnatifid, and 

 upper ones 3-lobed or entire : heads rather small : rays only quarter-inch long : receptacular 

 bracts only marginal : palese of the pappus ovate or oblong-ovate, acuminate, often erose- 

 deiiticulate, not longer than the tube of the corolla. — Proc. Am. Acad. xix. 18. — San Luis 

 Obispo, California, M. E. Jones. 

 • L. Fremonti, Gkay. A foot high, minutely pubescent, not glandular: leaves not ciliate, 

 nearly all piunately parted into oblong-liuear or spatulate sliort lobes : rays ample, half to 

 three-fourths inch long : receptacular bracts to many of the flowers : pale:u of the pappus 

 from ovate to oblong-lanceolate, tapering into a subulate awn, nearly equalling the corolla, 

 the margins entire, accompanied by a few free long-villous hairs, which much exceed those 

 of the surface of the akene. — PI. Pendl. 103, Bot. Calif, i. 370. Calliaclti/ris Fremonti, Torr.' 

 & Gray, Jour. Bot. Nat. Hist Soc. v. 140. — California, upper valley of the Sacramento to 

 Tuolumne Co. ; first coll. by Fremont. 



■>— H— Pappus subulate-arifetiform ana unequal and naked, or none : chaffy bracts to most of the 

 disk-flowers: herbs loosely erect or diffuse (about a foot high), not glanduliferous, with herbage 

 glabrous or minutely pubescent, but the margin of the leaves and yet more the base of tlie 

 bracts strongly hispidulous-ciliate: lower leaves piunately parted or lobed; upper entire: heads 

 showy, with ample usually particolored rays. 



ill. Calliglossa, Gka v, 1. c. Akenes villons-pubescent or partly glabrate : pappus of usually 

 several (10 tc 18) very unequal and rigid subulate awns, which are somewhat scabrous or 

 slightly hirsute near the dilated base, the m:irginal ones rather shorter than the corolla, the 

 smaller hardly half as long. — Ozj/ura rf/ys((/////MHu,V/ts, Lindl. Bot. Reg. t IS.'JO; Fiscli. &

 awns (and these sometimes slender) and to some intermediate rudiments or snuill awns: 

 leaves less lobed. — Petaluma, Santa Kosa, and elsewhere, north of Bay of San Francisco, 

 A'lirlierrij, LSolander, &c. 



L. Chrysanthemoides, Gray, 1. c. Akenes wholly glabrous, broader, \\\t\\ no eiiigynons
