LagophyUa. COMPOSITE. 313 



— Lepidostephanus madioides, Bartl. 1. c. — Open grounds; fl. in spring, throughout the 

 western part of California ; first coll. by Douglas. 



126. LAG-OPH"£XiLA, Nutt. (Acr/ds, a hare, <j>v\\ov, foliage.) —Slen- 

 der (Pacific N. American) herbs, paniculately much branched, usually more or 

 less cinereous with sericeous pubescence (this so long and copious on the crowded 

 upper leaves of the original species as to have suggested the generic name, from 

 some likeness to a hare's foot) : leaves narrow, entire or nearly so, the lower 

 opposite, upper alternate, sometimes bearing small tack-shaped glands : heads 

 small, with " pale yellow " or white and rose-tinged rays, apparently vespertine. 

 Bracts and chaff promptly deciduous with the mature akenes, leaving the naked 

 receptacle terminating and little thicker than the peduncle. — Trans. Am. Phil. 

 Soc. 1. c. 390 ; Torr. & Gray, Fl. ii. 402. 



§ 1. Holozoxia. Perennial and spreading by creeping scaly rootstocks : 

 pubescence all short : heads naked, scattered, mostly slender-peduncled : corollas 

 white or purplish-tinged: chaff of receptacle connate into a 9-12-toothed cup: 

 ray-akenes bearing a shallow entire or denticulate cupule in place of pappus (as 

 sometimes in Layia) : ovary of sterile disk-flowers occasionally bearing 2 to 5 

 nearly capillary naked bristles, which are very caducous, sometimes almost equal- 

 ling the corolla. — Holozonia, Greene, Bull. Torr. Club, ix. 122, 146. 



L. filipes, Gray. Rootstocks elongated, rigid, partly sheathed by the approximate pairs 

 of connate scales : stems diffusely branched : filiform branchlets and peduncles glabrous 

 or sparsely glandular : cauline leaves linear, minutely soft-villous ; those of the branchlets 

 minute, oblong, commonly beset with short-stipitate dark glands : involucre loosely villous ; 

 its bracts little longer than the clavate-obovate obscurely 5-nerved akene, which bears a con- 

 spicuous white saucer-shaped cupule. — Pacif. R. Rep. iv. 109, Bot. Mex. Bouud. 101, & Bot. 

 Calif, i. 367. Hemizonia filipes, Hook. & Arn. Bot. Beech. 356; Torr. & Gray, Fl. ii. 359. 

 Holozonia filipes, Greene, Bull. Torr. Club, 1. c, where the peculiar characters were pointed 

 out, and not unnaturally taken to be generic. — Rocky hills near streams, Napa Co. to Men- 

 docino Co. ; first coll. by Douglas. 



§ 2. Lagophtlla proper. Annuals : heads subtended by bracteal leaves 

 which may sometimes imitate an outer involucre, disposed to be sessile and glom- 

 erate, or at length short-peduncled : no cupule or pappus to the akenes : chaff or 

 bracts of the receptacle mostly quite distinct : stems below smooth and glabrous, 

 or early glabrate. 



* Green or barely cinereous, not caneseent : heads loose or scattered : ligules much exserted, pale 

 yellow ? 



L. dichotoma, Bektii. Stem a foot or two high, dichotomously paniculate ; the branch- 

 lets puberulent : leaves sparse ; cauline spatulate, occasionally dentate, strigulose-pubescent ; 

 of the branchlets short, hirsute-ciliate, as also the broadish bracts of the involucre, and with 

 small and sparse or no glands : akenes obovate, much obcompressed, no nerve or keel to the 

 ventral.face. — PI. Hartw. 317; Gray, Bot. Calif, i. 366. — Plains of Feather River, on the 

 Sacramento, and-Lake Co., California, Hartweg, Fitch, Bigelow, Mrs. Curran. 



L. glandulosa, Gray. Stem virgately paniculate, slender, » foot or two high: leaves 

 cinereous-puberulent, linear or the radical spatulate-lanceolate, entire, sometimes even the 

 lower as well as the small and scattered upper ones (also the branchlets) beset with small 

 tack-shaped glands, sometimes these all but or quite absent : bracts of the involucre and the 

 outer subtending bracts resembling the ordinary leaves, and inconspicuously if at all ciliate : 

 akenes nearly of the following. — Proc. Am. Acad. xvii. 219. — Not rare from Butte Co. to 

 Mariposa, Mrs. Bidwell, G. R. Vasey, Lemmon, Mrs. Curran, Congdon. Badly named, the 

 glands inconstant in this, and occasionally seen in all the species.
