Californian), barely hairy ; with opposite entire linear leaves, and slender-peduncled 

 heads of yellow flowers terminating the branches. DC. Prodr. v. 663, in part; 

 Benth. & Hook. Gen. PI. ii. 398. 



1. B. microglossa, DC. Sparsely hairy, a span high, branching : rays 1 to 3, 

 inconspicuous, shorter than their style : appendages to the anthers lanceolate : 

 style-appendages broadly subulate : akenes minutely and sparsely hispid. 



Low ground, in the neighborhood of San Francisco. Heads a quarter to a third of an inch 

 in length. 



2. B. leptalea, Gray. Nearly glabrous : stems filiform, mostly simple : leaves 

 very small and narrow : rays 4 or 5, longer than their style but shorter than the 

 disk : appendages to the anthers almost filiform : style-appendages narrowly and 

 abruptly subulate from a broad base : akenes minutely scabrous-hispid. Proc. 

 Am. Acad. vi. 546. 



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

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



67. BJERIA, Fischer & Meyer, Benth. 



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

 usually fertile. Involucre canipanulate 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. 

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

 filiform tube equalling or longer than the canipanulate or cyathifonn 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 chafty- 

 dilated base, or of awned or partly awn-pointed chaffy 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. & Hook. Gen. PI. 1. c. ; Gray, Proc. Am. Acad. 

 ix. 196. Burrielia, DC. 1. c., excl. sp. ; Torr. & Gray, 1. c., excl. sp. Dichceta,

1. Pappus uniformly none : akenes someivhat rounded at the apex, the areola 

 rattier small : leaves all entire. (Bceria, 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 t6 12, oblong-evate 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. 1835, 

 fe Sert. Petrop. t. 7 ; Don., Brit. Fl. Gard. ser. 2, t. 395. Burrielia hirsuta, Nutt.

Var. macrantha (Burrielia chrysostoma, var. macrantlia, Gray, Pacif. R. Rep. 

 iv. 106) is a form strikingly large in all its parts, a foot or more high ; the head 

 broad and ample ; the oblong rays from half to three quarters of an inch long.
