villous wool all-straight and erect, a little or sometimes much shorter than the rather 

 slender bristles. — Hook. Ic. PI. t. 32G. Madaroglossa lieterotricha, 1 >C. 



Open grounds, through the western part of the State, especially in the .San Joaquin Valley. 

 Heads with disk hall' an inch high ; the large and showy elongated rays three quarters of an inch 

 long. The copious stipitate black glands, intermixed with the short hispid and above apparently 

 somewhat viscid bristles, suggested the specific name. 



3. L. carnosa. Ton-. & Gray. Dwarf and depressed, rising only 3 to 5 inches 

 high, more or less hirsute-pubescent : leaves succulent, spatulate or the upper linear- 

 oblong, the lower often sinuate-pinnatitid : heads small: rays 8 to 10, very short 

 (slightly surpassing the involucre), apparently white : akenes both of ray and disk 

 pubescent : pappus dull whitish, its slender bristles very sparsely plumose with 

 straight villous hairs to much above the middle. — Madaroglossa carnosa, Mutt. 



Sands of the sea beach, San Diego (Xuttall), Monterey (Parry), Punta de Ios Reyes, Bigclow. 

 The rays (nowhere stated to be yellow) appear to be white, and they are very inconspicuous. 



* * Rays as well as dish-flowers yellow. 



4. L. hieracioides, Hook, & Am. A foot or so high, very hispid with long 

 and spreading rigid bristles, which above are somewhat viscid : leaves varying from 

 linear to oblong, laciniate-toothed or almost pinnatilid : heads small : rays 10 to 15, 

 small, a little exceeding the disk : disk-akenes minutely pubescent : pappus rusty- 

 brownish; the straight and erect villous hairs rather scanty and little shorter than 

 the bristles. ■ — ifiidm-nylossa hieracioides, DC. 



Open grounds, San Franeisen to .Monterey, ic. Stem not rarely spotted by the dark-colored 

 bases of the bristles. Leaves mostly only an inch or so in length. Heads only 3 or 4 lines high : 

 rays seldom - lines long : their akenes sometimes showing rudiments of pappus. 



5. L. gaillardioid.es, Hook. & Am. A foot or two high, loosely branched, 

 hispid and glandular like the preceding : leaves lanceolate or linear, the lower com- 

 monly pinnatilid : heads pretty large : rays 12 to 20, orange-yellow, cuneate-oblong, 

 twice or thrice the length of the disk : disk-akenes silky-pubeseent : pappus dull 

 while or rather rusty ; the erect and not abundant villous hairs all straight and con- 

 siderably shorter than the bristles. 



Open grounds, common through the western part of the State, especially near San Francisco 

 Bay. Rays in well-developed plants two thirds to three fourths of an inch long. Chair of the 

 receptacle sometimes (as originally described) among the outer disk-flowers, but commonly only 

 between the disk and ray. In Icelander's collection from Forest Hill. Placer Co., are specimens 

 andistinguishahle from /.. pentachceta of thai locality, and apparently growing with it, hut with 

 lie- pappus of the presenl sj Les. 



0. L. elegans, 'I'm it. >V dray. Resembles the pi eding. but rather hirsute than 



hispid, and the linear cauline leaves less pinnatilid : rays 10 to 12, lighter yellow, 

 obovate-CUneifonu, about twice the length of the disk: pappus mostly white; its 

 copious villous hairs much shorter than the awn like bristles, the inner crisped and 

 interlaced. - Mudarng/ossti e/,- : /,t/is, Xutt. 



Open grounds, Pkiah to Santa Barbara and Los Angeles. In the pappus this resembles 

 /,. ylandulosa : and the rays are similar, except in their color and rather larger size. 



§ 2. Pappus, receptacle, <il,indiil<tr herbage, and w!ml, ,ix/n;-t nf /he preceding section, 

 but the (•"> to -'') awns or bristles of the pappus naked, or rarely wanting, — 

 Caluohroa, Gray. (Callichroa, Fischer & Meyer.) 



7. L. pentachaeta, • iny. Sparsely hirsute or hispid as well as glandular. 

 loosely branched: leaves mostly pinnatifid and the lower even bipinnatifid, with 



long linear lobes ; rays large, golden yellow, obloilg-CUneiform : disk-akenes minutely 

 pubescent, sometimes almost glabrous: pappus of 5 or rarely fewer rigid smooth 

 bi i ties, or sometimes wanting. — Pacif. I.'. Rep. iv. 108, t. 16.

length.
