316 COMPOSITE. Liyia. 



3. CALLTGLOSSA, Gray, 1. c. Pappus wanting or of few or several flattened 

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

 Calliglossa, Hook. & Arn., with Oxyura, DC. & Lindl. 



* Rays pure white: only marginal receptacular bracts present: pappus aristifunn: habit of L. 

 gland/tlosa : a few small stipitate glands on the upper leaves and involucre. 



L. Douglasii, HOOK. & ARX. Low, sparingly hirsute or hispid : radical leaves piniiatifid- 

 deutate ; upper 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 palete, nearly equalling disk-corolla; their 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 

 Itiver, Douglas (the pappus in the specimen fulvous by discoloration) ; Austin, Nevada, 1882, 

 ,17. E. Jones (pappus bright white). Probably only a form of L. glandulosa 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 paleae: disk-akenes more or less villous-hirsute. Calli- 

 achyris, 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 pinnatifkl, and 

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

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

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

 Obispo, California, M. E. Junes. 



Li. Fremonti, GRAY. A foot high, minutely pubescent, not glandular: leaves not ciliate, 

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

 three-fourths inch long : receptacular bracts to many of the flowers : paleaj 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. Feudl. 103, Bot. Calif, i. 370. Calliuchyris Fremonti, Torr. 

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

 Tuolunme Co. ; first coll. by Fremont. 



H -i Pappus subulate-aristiform anu 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 

 plabrous 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 

 showy, with ample usually particolored rays. 



Li. Calliglossa, GRAY, 1. c. A kenes villous-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 marginal ones rather shorter than the corolla, the 

 smaller hardly half as long. O.ri/wa chrysanthemoides, Lindl. Bot. Reg. t. 1850; Fisch. & 

 Meyer, Hort. Petrop. t. 6. Calliglossa Duitr/Iasii, Hook. Arn. Bot. Beech. 356. Ca/lichroa 

 ( Calliglossa) Douylasii, Torr. & Gray, Fl. ii. 396. California, common around San Fran- 

 cisco Bay; probably first coll. by Douglas. 



Var. oligochseta, GRAY, Bot. Calif. 1. c. Pappus reduced to the two marginal 

 awns (and these sometimed slender) and to some intermediate rudiments or small awns: 

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

 Newberry, Bolander, &c. 



L. chrysantliexnoid.es, GRAY, 1. c. A kenes wholly glabrous, broader, with no epigynons 

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

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

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

 Suppl., & Walp. Repert. ii. 631. Hartmannia ciliata, DC. Prodr. v. 694. California, not 

 rare near San Francisco ; first coll. by Douglas.
