71. LASTHENIA, Cass. 

 Head luany-lloweruil, with f) to 15 pistillate rays; all tho flowers fertile. Invo- 

 lucre a single series of herbaceous scales, united by their edges almost to their tii)s 

 into a 5 - 15-toothed campanulate or hemispherical cup. Receptacle conical, naked, 

 muiicate or papillose with projecting points which bear the akenes. Kays very 

 shurt and included, oblicjuely truncate, or in one species large and exserted : disk- 

 corollas with narrow tube and campanulate or cyatliiform 4 - 5-lobed limb. An- 

 thers ti[)i)ed with small ovate or obK)ng appendages. 8tyle-branches capitate-truncate 

 or obtuse. Akenes linear or linear-oblong, compressed (tho faces liariUy if at all 

 angletl or obviously costato), their terminal areola largo, bearing a pappus of 5 to 10 

 lirm and thickish mostly subulate-pointed scales nearly as long as the disk-corolla, 

 or in one species none. — Slender (Western American) annuals, green and gla- 

 brous or nearly so, somewhat succulent ; with the linear and mostly entire leaves 

 opposite (even to the uppermost), sessile and more or less connate at the base ; the 

 heads of yellow llowers on terminal peduncles, M'hich are more or less thickened at 

 tho summit, sometimes nodding. — The lirst section is intermodiato between tho 

 genuine Ldslhenia and iMonulcpui.

1. L. glabrata, Lindl. A span to 2 feet high, simple or branched from the 

 base and dill'use, glabrous or slightly pubescent : leaves sometimes one-toothed 

 or lol)ed on each side (1 to 3 inchiis long, 1 to 3 lines wide) : involucre 10-15- 

 tootlied : rays oval, l! - .3-tootlnHl at the end : disk-corollas as long as the glabrous 

 akene, their lol)es sparsely papillose-barbellate outside (as in Munulupia). - — L. t'ali-

Low grounds, coniniou from Mcn<locino Co. and San Francisco Bay to Santa Bnrbara. In the 

 larger forms showy ; the expanded ray becoming an inch or more in diameter. 



§ 2. Corollas xhort ; the few anil very short rays wholly inconspicuous, not txceediiuj 

 the disk-jUnvers, little surpassiiKj the j)aj>jms. — True L.\STIIKNIA, 



2. L. glaberi'ima, Di-'. Low, with stems weak or decumbe,nt, a span or two 

 long: leaves rather succulent, entire (an in(;h or two long, a line or two broad): 

 involucre broad, about 15-toothed: corollas shorter than the rather broadly linear 

 and jninutely i»ubescent akenes, their lobes naked : jjappus of 5 to 10 firm chalfy 

 scales, 2 or 3 of thcMu subulate pointed or short-awned, the others mostly lacini- 

 ately cleft or erose. 



Wi't meadows, along or near the coast, from Monterey / to Mendocino Co., and Oregon. 

 Involucre about 3 lines high. Hecejitacle in-oadly conical. Ours is not very dillcrent from tho 

 Chilian s|ic(Ucs, the only remaining one of the genus.
