300 COMPOSITE. Leptosyne. 



§ 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 : perenni al; with more fleshy_leaves_and 

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

 Nutt. Trans. Am. Phil. Soc. 1. c. 363. 



L. maritima, Gray. Stems low , fleshy-herbaceous from a thick base or caudex : branches 

 terminating 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 : rgysJ6_to_20, an inch or more 

 long, and disk-commonly an inch uudiameter. — Proc. Am. Acad. vii. 358, & Bot. Calif. 1. c. ;

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



L. gigantea, Kellogg. Meshy-woody stem_2jB_8 .fe.et_.high, 1 to 5 inches thick, leafy at 

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

 inch in diameter) on short_corymbgsely- clustered, peduncles: inner bracts of the involucre 

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

 on the mountains near Sta. Barbara and San Miguel, and islands off the coast ; first coll. by

 Island, Palmer.) 



§ 3. PugiopIppus. 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 bidentate at 

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

 pale_e : annuals with the habit and otherwise the character of Euleptosyne ; the 

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

 yet sometimes neutral or with mere included rudiment of style. — Agarista, DC.

 R. Eep. 1. c, & Proc. Am. Acad. vi. 545, viii. 659. 



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

 and with long often scapiform pednncles : leaves once or twice ternately or quinately parted 

 into narrow linear lobes: involucre half-inch or less high; its outer bracts linear or nearly 

 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 the margins, sparsely so or naked on one or 

 both faces, twice the length of the palete of the pappus. — Pugiopappus Bigelovii & P. Breweri, 

 Gray, 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- 

 ern part of California, from San Buenaventura and Tejon to the Mohave Desert. 



L. oalliopsidea, Gray. Ajoot or two high, rather stout and leafy, with p eduncles a span 

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

 bracts of the outer involucre broadly ovate, thick, a little shorter than the narrowly ovate 

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

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

 thin-winged ; disk-akenes cuneate-oblong, little longer than the palese of the pappus, very 

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

 or less margined. — San Bernardino Co. at Mohave Station, &c, Lemmon, Pringle.
