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



67. BOERIA, Fischer & Meyer, Benth. 



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

 usually fertile. Involucre cainpanulate 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. 

 Pays oval or oblong, entire or 2 — 3-tootbed : disk-corollas with a very slender or 

 filiform tube equalling or longer than the campamdate 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 chaffy- 

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

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

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

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

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