§ 2. TuckermXnnia. Akenes plane, oblong, smooth and glabrous, with 

 obscure wing-like margin : pappus none or sometimes the margins continued into 

 an acute tooth or short naked awn : rays fertile, oblong, obscurely toothed at the 

 apex : ring of disk-corollas beardless : perennial, with more flesliy leaves and 

 thickened succulent stem or caudex: the heads large and showy. — luckermannia,

L. maritima Gray. Stems low, fleshy-herbaceous from a tliick ba=e or caudex : branches 

 terminatino- in monocephalous peduncles of a span to a foot in length : leaves bipinnately 

 divided into narrowly linear lobes of a line or two in width: rays 16 to 20, an inch or more

 of California, at Sau Diego and on the adjacent islands. 



L. gigantea, Kellogg. Fleshy-woody stem 2 to 8 feet high, 1 to 5 inches thick, leafy at 

 top : leaves twice or thrice pinnately divided into filiform lobes : heads smaller (disk half- 

 inch in diameter) on short corymbosely clustered peduncles : inner bracts of the involucre 

 with prominent midrib. — Proc. Calif. Acad. iv. 198; Gray, Bot. Calif, i. 356. — California,

§ 3. PugiopXppus. Akenes dimorphous ; those of the ray- or outermost disk- 

 flowers very like those of the preceding section (oval, flat, glabrous), either fer- 

 tile or sterile ; those of the disk also flat, but narrowly oblong, marginless, clothed 

 at least on the margins with long and soft-villous hairs (which are bidcntate at 

 apex under a lens), bearing a conspicuous pappus of a pair of linear triquetrous 

 palcce : annuals with the habit and otherwise the character of Euleptosyiia ; the 

 ample golden yellow rays multinervose, commonly styliferous, not rarely fertile, 

 yet sometimes neutral or with mere included rudiment of style. — Af/arista, DC.

L. Bigelovii, Gray. A foot or less high, with the habit of L. Dour/Iasii, leafy only at base,

 so, inner oblong-ovate: rays obovate or quadrate-oblong, half to two-thirds inch long, 10-12- 

 nerved : ring of disk-corollas beardless : ray-akenes oblong, with narrow callous-winged mar- 

 gin ; disk-akenes elongated-oblong, very villous at tlie margins, sparsely so or naked on one or 

 both faces, twice the length of the palea>. of the pappus. — Pugiopappus Bigelovii & P. Breircri, 

 Grav, Proc. Am. Acad. viii. 660, & Bot. Calif. 1. c, the former described from immature and 

 incomplete specimens, in which the villosity of the disk-akenes was little developed. — South-

L. calliopsidea, Gray. A foot or two high, rather stout and leafy, with peduncles a span 

 long : lobes of the leaves narrowly linear, sometimes incised : heads rather large and broad : 

 bracts of the outer involucre broadly ovate, tliick, a little shorter tiian the narrowly ovate 

 inner ones : rays broadly cuneate-obovate, commonly an inch long and three-fuurtlis inch 

 wide, 15-20-nerved: ring of the disk-corollas pubescent: ray-akenes broadly oval, distinctly 

 tliin-winged ; disk-akenes cuneate-oblong, little longer than the palcaj of the pajjpus, very 

 long villous on the margins and inner face. — Agarista calliopsidea, DC. Prodr. v. 569 ;
