along the margin with yellowish large glands: involucre campanulate to 

 turbinate, its bracts more or less glauduliferous. — Plains of the lower 

 San Joaquin and southward. 



3. L. ppctinata, Greene, Proc. Philad. Acad., 1895, p. 548. Slender 

 and very diffuse, the ascending or more widely spreading and almost 

 prostrate branches a foot long or more; herbage scarcely tomentose even 

 when young, green, sparingly stipitate-glandular and scabrous through- 

 out; only the lowest leaves woolly, these and also those of stem and 

 branches pectiuate-pinnatifid, the segments pungently spinescent-tipped: 

 involucral bracts narrow, acute, glandular-puberulent. —Sandy soil near 

 the sea at Monterey, Hartweg, Parry, Tideslrom and others. 



4. L. parvula. Low and slender, branched from the base, the 

 spreading branches only 3—6 in. long; herbage more or less white-woolly 

 and also glandular, some or all of the glands stipitate: radical leaves 

 somewhat lyrately pinnatifid, the cauline 5 7-lobed, the lobes spines- 

 cent; involucres small and almost campanulate, only li^b lines high and 

 almost as broad, the short bracts numerous and imbricated, the short 

 outer ones often woolly, the inner granular-glandular and also with a 

 few large glands, all abruptly acute: bristles of the pappus very fine and 

 only light-brownish. — Common in the interior of Monterey and San 

 Luis Obispo counties, Hickman, Lemmon. It seems to have formed a 

 part of Gray's L. ramulosa tenuis, that author not having known that 

 the flowers are yellow. 



* * Flowers lilac or purplish. 

 ■t— Bracts of the involucre without cartilaginous tips. 



5. L. ranmlosa, Gray, in Beuth. PI. Hartw. 314 (1849). Erect, 1—2 

 ft. high, very loosely branching, the glabrate branchlets and upper 

 leaves more or less hirtellous and glandular: leaves oblong to lanceolate, 

 the lower spatulate, entire or toothed, the small ones of the branchlets 

 with partly clasping base: involucre campanulate or turbinate, 10 20- 

 flowered: corollas short, purple: style-appendages with minute setiform 

 tip. — Dry hills from middle sections of the State uorthwai'd. 



6. L. leptoclada, Gray, Proc. Am. Acad. vii. 351 (1868). Taller and 

 more slender, with almost filiform branchlets bearing few or solitary 

 5— 20-flowered heads: upward leaves somewhat sagittately adnate to the 

 branches at base: involucre turbinate; its bracts in many ranks: corollas 

 elongated: style-appendages with a conspicuous subulate tip. — Same 

 range as the preceding. 



7. L. adenophora, Greene, Bull. Calif. Acad. i. 190 (1885). Erect, 

 1 — 2 ft. high, loosely branched from near the base: stem-leaves }^ — 14' in.
