COMPOSITE. 377 



long, ovate and roimd-ovate, piingently acute, sessile and somewhat 

 cordate-clasping, densely soft-woolly above, glabrate beneath, the mar- 

 gins closely beset with small stipitate glands: bracts of the narrow- 

 camjtannlate involucres very acute, suberect, more or less stipitate- 

 glandular: coiollas red-jjurple: bristles of the pappus more or less 

 comjtletely united into 5 palefe.— Mountains of Lake and Colusa coun- 

 ties. 



8. L. neinaclada, Greene, 1. c. Size of the last, but the branching 

 more paniculate: leaves lightly floccose above, glandular-scabrous be- 

 neath: branchlets very slender and heads small (3— 5flowered); bracts 

 of the involucre with spreading tips; pappus of few or many awn-like 

 bristles which are sometimes by cohesion reduced to 5 broad awns 

 or paleae as in the last.— Foothills of the mountains on both sides of the 

 Sacramento, in El Dorado and Colusa counties. 



9. L. virgata, Gray, in Benth. PI. Hartw. 315 (1849). More densely 

 woolly: stem and virgate branches rigid: upper leaves appressed, con- 

 cave, carinate-nerved: heads spicately sessile in the axils of the leaves: 

 involucre cylindrical, woolly, 5 — 7 flowered : fl. nearly white : style- 

 branches with a conspicuous subulate tip.— Sandy plains of the Sacra- 

 mento and San Joaquin. Sept. 



10. L. hololenca. With the habit of L. ranmlosa, but stouter, the 

 branches rigidly ascending, the whole plant even to the involucre white- 

 tomentose: leaves all entire, the oblong and ovate-oblong cauline ones 

 sessile and cordate-clasping, ending in a short spinescent tip: heads 

 broadly turbinate ; involucral bracts short and in only a few series, 

 straight and spinescent at tip: corollas red-purple: pappus of rufous 

 bristles. — Low hills east of the Santa Eosa Valley, Sonoma Co.; collected 

 by the author, 15 Sept. 1888. 



■•— -i— Iriner bracts of the involucre cartilaginous-aristate. 



11. L. Parryi, Greene, Bull. Calif. Acad. i. 192 (1885). Woolly 

 throughout, 2 — 10 in. high, erect, not stout, sparingly branched: heads 

 few and spicate, or some solitary at the ends of the branches: corollas 

 pink: pappus reddish: style-appendages bristly-hairy but not cuspidate. 

 — Mountains of Kern Co., at Keene Station, etc. 



12. L. nana, Gray, in Benth. PI. Hartw. 315 (1849). Stout short 

 branches prostrate, only 2—4 in. long, or even obsolete and the heads 

 sessile among the radical leaves, the whole plant white-tomentose except 

 the long white cartilaginous awns of the inner bracts of the involucre; 

 heads large, sessile: corollas red: pappus dark-red.— Sandy plains and 

 hills in the valleys of the Sacramento and San Joaquin. Aug., Sept.
