Santa Lucia Mountains, on the Nacimiento River, Brewer. Receptacle subulate, gradually 

 tapering from a broadish base, little shorter than the involucre. 



67. BMBIA., Fischer & Meyer, Benth. 

 Head many-flowered, with 5 to 12 or 14 exserted pistillate rays; all the flowers 

 usually fertile. Involucre campanulate or hemispherical, formed of a single series 

 of herbaceous oval or oblong-lanceolate flat scales. Eeceptacle strongly and usually 

 acutely conical, rough or muricate with projecting points which bear the akenes. 

 Eays oval or oblong, entire or 2 - 3-toothed : disk-corollas with a very slender or 

 filiform tube equalling or longer than the campanulate or cyathiform 5-lobed limb. 

 Anthers oblong, bimucronulate or somewhat sagittate at base, tipped with a deltoid- 

 ovate or oblong obtuse appendage. Style-branches tipped with a very short capitate- 

 truncate or flattened and very obtuse appendage, but its centre sometimes pointed 

 with a short bristle or rarely a more substantial cusp. Akenes linear, subclavate, or 

 linear-cuneate, more or less compressed and 4 - 5-angled or nerved ; those of the ray 

 not at all embraced by the involucral scales. Pappus of a few awns with chafly- 

 dilated base, or of awned or partly awn-pointed chafty scales, or else wholly wanting. 

 — Annuals (all Californian), mostly low or small, pubescent or almost glabrous ; 

 with opposite linear and entire leaves, or else laciniate-pinnatifid into linear lobes, 

 and small or middle sized heads of yellow flowers on slender peduncles, terminating 

 the stem and branches. — Benth. k Hook. Gen. PI. 1. c. ; Gray, Proc. Am. Acad,

§ 1. Pa2->inis uniformly none : akenes somewhat rotmded at the apex, the areola 

 rather small : leaves all entire. (Ba^ria, Fischer & Meyer.) 



1. B. chrysostoma, Fischer & Meyer. More or less pubescent, or the margin 

 of the narrow linear leaves sparsely hirsute, a span to a foot and a half high : scales 

 of the involucre 5 to 12, oblong-ovate or oval-oblong, acute : rays as many, oval 

 or oblong : receptacle rather broadly conical but acute : akenes subclavate-linear, 

 glabrous but most commonly glandular. — Fischer & Meyer, Ind. Sem. Dec. l^.io,
