Lasthenia glabrata californica Jepson, I'M. \V. Middle Calif. 519. 1901. 



Stems simple, or corymbosely branched above, erect, 1-6 dm. high, perfectly glab- 

 rous, or finely puberulent in the inflorescence; leaves linear or the upper lanceolate, entire or 

 irregularly toothed, usually 3-10 cm. long, mostly connate and sheathii: , the upper 



pairs frequently much dilated near the stem and forming an open cup; peduncles 110 cm. long, 

 moderately enlarged beneath the erect heads; bracts of the involucre well united into a broadly 

 hemispheric cup 5-8 mm. high, with acuminate ciliate teeth; ligules conspicuously exserted, 

 5-10 mm. long; disk-corollas 3 mm. long, about equaling the achenes, the tube glandular; 

 achenes slightly compressed, obtusely angled, narrowly oblong-obovate, apparently smooth 

 but usually minutely papillate, sometimes well covered with yellow rough gland-like points 

 (var. Coulteri) ; pappus none. 



Tvi'E LOCALITY: California. 



Distribution: Moist soil and borders of marshes, western California and Lower California.

 Infantea Remy, in C. Gay, Fl. Chil. 4: 257. 1849. 



Low annuals with broom-like branched stems. Leaves alternate, the lower pinnately 

 divided into 3-5 linear leaves, the upper entire. Heads small, apparently discoid. Involucre 

 globose ; bracts 4-6, broad, in two equal series, concave and more or less enclosing the marginal 

 achenes. Receptacle small, conic. Marginal flowers pistillate; corollas tubular, shorter than 

 the styles, with 2 or 3 short teeth. Disk-flowers hermaphrodite and fertile; tube of the corolla 

 short; throat campanulate; limb 5-lobed. Achenes obpyramidal, hirsute and glandular- 

 pubcrulent, rather bluntly angled; pappus of 8-12 oblong, obtuse squamellae.

Subtribe 11. ERIOPHYLLANAE. Floccose-pubescent plants. Heads 

 radiate or discoid. Involucre from hemispheric to campanulate; bracts 

 distinct, strongly concave or boat-shaped, and partly closing around the mar- 

 ginal achenes, or more or less united into a cup. Ray-flowers pistillate 

 and fertile; ligules mostly yellow. Disk-flowers hermaphrodite and usually 

 fertile; corollas yellow; throat campanulate or funnelform. Achenes more or 

 less elongate-obpyramidal, 4-5 -angled. 



Ray-corollas with a lobe on the inner side of the throat, opposite the ligule. 52. Monolopia.
