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

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

 — Calliglossa^ Hook. & Arn., with Oxyitra, DC. & Lindl. 



* Rays pure white: 011I3' marginal receptacular bracts present: pappus aristifunn: lial^it of Z.. 

 (/landulosa : a few small stipitate glands on the upper leaves and involucre. 



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

 deiitate; U])per linear and entire: rays rather short, broad, 3-cleft : lobes of disk-corolla hir- 

 sute outside : akeues narrow, those of the disk villous-pubescent : pappus of about 10 minutely 

 scabrous linear-subulate flat ])alea3, nearly equalling disk-corolla; their margins toward the 

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

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

 iJiver, Dotifjlas (the pappus in the specimen fulvous by discoloration ) ; Austin, Nevada, 1882, 

 jl/, E. Jones (pappus bright white). Probably only a form of L. glandulosa with more 

 paleaceous and almost uaked pappus. 



* * Ra^'s yellow at base, white or pale at summit : bracts of the involucre lanate-ciliate at the 

 basal mari^ius where infolded around the akene : both ray- and disk-akenes nicstly oblong- 

 obovate. 



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

 acliyris, Torr. & Gray. 



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

 on and near the involucre : leaves hispidulons-ciliate, narrowly linear, simply pinjiatifid, and 

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

 bracts only marginal : palea; of the papjuis ovate or oblong-ovate, acuminate, often erose- 

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

 Gbispo, California, M. E. Jones. 



Li. Fremonti, Gray. A foot high, minutely pubescent, not glandular: leaves not cihate, 

 nearly all pinnately parted into oblong-linear or spatulate short lobes : rays ample, half to 

 three-fourths inch long : recejjtacular bracts to many of the flowers : palesc of the pappus 

 from ovate to ol)long-lauc"eolate, tapering into a subulate awn, nearly equalling the corolla, 

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

 of the surface of the akene. — PI. Feudl. 103, Bot. Calif, i. 370. CalUachyris Fremonti, Torr. 

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

 Tuolumne Co. ; first coll. by Fremont. 



■^ -1— Pappus subulate-aristiform 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 the 

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

 sliowy, witli ample usually particolored rays. 



Lj. Calliglossa, Gray, 1. c. Akenes villous-pubescent or partly glabrate: pappus of usually 

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

 slightly hirsute near the dilated base, the marginal ones rather shorter than the corolla, the 

 smaller hardly half as long. — O.rijnra chri/sant/>emoides,JAntl\. Bot. Keg. t. IS.'iO; Fisch. & 

 Meyer, Hort. Petrop. t. 6. Calliglossa Douglasii, Hook. & Arn. Bot. Beech. 356. Callichrua 

 [Calliglossa) Doiiglnsii, Torr. & Gray, PI. ii. 396. — California, common around San Fran- 

 cisco Bay; probably first coll. by Douglas. 



Var. oligocheeta, Gray, Bot. Calif. 1. c. Pappus reduced to the two marginal 

 awns (and tiicse sometime.i slender) and to some intermediate rudiments or small awns : 

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

 Newberry, Bolander, &c. 



L. chrysantliemoides, Gray, 1. c. Akenes wholly glabrous, broader, with no epigynous 

 disk (the base of corolla covering the top of tiie ovary) : no pappus: receptacle becoming 

 convex: otherwise quite like the preceding species. — Oxgura chrysanthemoides, DC. (in 

 Lindl. Syst. Nat. &) Prodr. v. 693, not of Bot. Reg. Tollatia chrysanthemoides, Eudl. Gen. 

 Suppl., & \A'alp. Kepert. ii. 631. liartmannla ciliata, DC. Prodr. v. 694. — California, not 

 rare near San Francisco ; first coll. by Douglas.
