Part 1, 1914] CARDUACEAE : HELENIEAE 79 



oblong-elliptic ligules 4-8 mm. long; achenes nearly prismatic but narrowed below, angled, 

 strigose ; pappus of 2-4 awns and about 6 truncate- fimbriate intervening squamellae, or rarely- 

 wanting and the achenes then glabrous. (Var. tenella is the slender form with small heads 

 and ligules and mostly entire leaves; it grows in lighter and scarcely alkaline soil.) 



Type locality: Santa Barbara, California. 



Distribution: Low moist or saline ground, from Bodega Bay, California, to San Quentin, Lower 

 California. 



9. Baeria maritima A. Gray, Proc. Am. Acad. 9: 196. 1874. 



Burrielia maritima A. Gray, Proc. Am. Acad. 7: 358. 1868. 



Annual, with weak and reclining stems, succulent, woolly or loosely villous, especially on 



the margins of the involucral bracts, but often glabrate; leaves oblong-linear, 3-20 mm. wide, 



entire or some sparingly dentate or incised; peduncles often very short but usually 1-5 cm. 



long; involucre hemispheric, about 5 mm. high, its 5-7 bracts broadly elliptic, rather obtuse; 



receptacle conic or rarely somewhat hemispheric, acute, strongly muricate, not pubescent; 



ray-flowers 6-8, the oval ligules rarely exceeding 3 mm. long and scarcely equaling the disk; 



achenes linear-clavate, the surface completely covered by the dense appressed pubescence; 



pappus of 3-5 subulate awns and as many intervening laciniate squamellae. 



Type locality: Farallone Islands, off the coast of middle California. 



Distribution: Coast and adjacent islands of middle California, north to Vancouver Island.

Lasthenia Burkei Greene, Man. Bay Reg. 204. 1894. 



Annual, very slender, or sometimes slightly succulent, simple to freely branched, erect, 

 0.8-3 dm. high, nearly glabrous below, densely and finely pubescent on peduncles and in- 

 volucres; leaves mostly parted into linear lobes but some of the upper nearly filiform and 

 entire, rarely all entire in slender plants ; peduncles much exceeding the upper leaves ; involucre 

 hemispheric, 4-6 mm. high; bracts 10-12, broadly ovate, acute, overlapping, usually distinct 

 but occasionally united near the base {Lasthenia conjugens), not keeled, strigose-pubescent at 

 least near the margins, inclined to be deciduous with their achenes at maturity; receptacle 

 subglobose or dome-shaped, low-muricate, densely hirsute; ray-flowers about 10-12, the 

 ligules elliptic and 3-6 mm. long; disk-corollas 2.5-3 mm. long, the tube hirsutulous and glandu- 

 lar; achenes scarcely more than 1 mm. long, prismatic or slightly compressed, black, upwardly 

 scabrous; pappus of 1-4 slender awns and 4 or more short quadrate lacerate squamellae, or the 

 pappus wanting and the achenes then smooth and shining. 



Type locality: California. 



Distribution: Middle California, especially in the Sacramento Valley.
