§ EuBAEElA. Pappus of uniform (or mainly uniform) and entire awned or 

 pointed paleae or chaffy-based awns, or wanting (e-s-en present or absent in the 

 very same species) : receptacle muricate-roughened : ligules mostly conspicuous : 

 leaves linear and entire, except in one species. — Burrielia, Torr. & Gray, 1. c, 

 excl. B. microglossa. 



* Akenes slenderh' subclavate-linear: stjle-tips abruptly terminated by a conspicuous narrow- 

 subulate appendage wliich usually surpasses the broad basal portion: receptacle slender-subu- 

 late and elongated in the manner of Burrielia: heads small: involucral bracts and oval rays 

 5, or sometimes only 4. 



B. leptalea. Wholly glabrous : stems filiform, a span high : leaves nearly filiform, quarter 

 to half inch long : involucre 2 lines high : ligules mostly as long : anther-tips filiform : pap- 

 pus of 2 or 3 scabrous flattened aivns with gradually dilated base. — Burrielia leptalea, Gray, 

 Proc. Am. Acad. vi. 546, & Bot. Calif, i. 37.5. — Jlunterey Co., valley of the Xacismento, 

 Brewer, and the Salinas, Greene. Known only as an exiguous vernal plant : probably also 

 occurs in a larger form. 



B. debilis, Greene in herb. Minutely pubescent: stems weak, 6 to 10 inches long: leaves 

 flaccid, linear, the largest inch and a half long : involucre 2 or 3 lines high : ligules hardly 

 over a line long : anther-tips ovate-lanceolate : papptis of 3 or 4 firm ovate-lanceolate and 

 awned paleae, or in sume heads none, then the akene with narrower apex. — Plains of Fresno 

 and mountains of Kern Co., Greene. 



* * -A-kenes more clavate. with scanty aristiform pappus or commonly none, then less truncate or 

 slightly contracted at summit, either glabrous or minutely papillose-glandular in same species: 

 style-tips capitate and mostly with a small apiculation: receptacle conical: large-flowered and 

 with some hirsute pubescence, a foot or so high unless depauperate: rays and plane involucral 

 bracts 7 to 12, — BaeHa, Fisch. & Meyer, 1. c 



B. macrantlia, Gkay. Apparently perennial, rather stout, with peduncles 4 to 8 inches 

 long; leaves more or less 3-nerved and obtuse, 2 or 3 lines wide {the lower 4 to 8 inches 

 long), hispidly ciliate, at least toward the base : head about half-inch high and broad : invo- 

 lucre of about 12 hirsute-pubescent thickish-herbaceous bracts: ligules half to three-fourths 

 inch long. — Proc. Am. Acad. xix. 21. B. chrt/sostoma, \ai. macrantha. Gray, Proc. Am. 

 Acad. ix. 196, & Bot. Calif. 1. c. Burrielia chri/sostoma, var. macrantha. Gray, Pacif. R. Kep. 

 iv. 106. — Coast of California, north of San Francisco Bay to Humboldt Co., Andrews, 

 Biq^loir, Bolander. 



Var. pauciaristata, Gray, 1. c. Clearly perennial, often only 6 inches high : leaves 

 shorter, hispid-ciliate : ligules only 4 or 5 lines long : pappus when present of 1 to 3 subulate 

 chaffy awns rather than paleee, little shorter than the akene. — Coast of Mendocino Co., 

 B"lander, Pringte. 



B. chrysostoma, Fisch. & lifter, 1. c. Annual, slender: leaves narrowly linear (a line 

 or less wide) : heads 3 or 4 lines high: bracts of the broad involucre 7 to 12, in depauperate 

 plants sometimes fewer: ligules 3 or 4 lines long: pappus (perhaps always) none. — Don, 

 Brit. Fl. Gard. ser. 2, t. 395 ; DC. Prodr. \ . 2.54 ; Gray, Bot. Calif, i. 375, excl. var. Bur-
