EUBAERIA. Pappus of uniform (or mainly uniform) and entire awned or 

 pointed paleaa or chaffy-based awns, or wanting (even present or absent in the 

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

 leaves linear and entire, except in one species. -- Burrieli a, Torr. & Gray, 1. c., 

 excl. B. microglossa. 



* Akenes slenderly subelavate-linear: style-tips abruptly terminated by a conspicuous narrow- 

 subulate appendage wliich usually surpasses the broad basal portion: receptacle .--lender-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 awns with gradually dilated base. Burrielia leptalea, Gray, 

 Proc. Am. Acad. vi. 546, Bot. Calif, i. 375. Monterey Co., valley of the Nacismento, 

 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 : pappus of 3 or 4 firm ovate-lanceolate and 

 awued palete, or in some heads none, then the akeue with narrower apex. Plains of Fresno 

 and mountains of Kern Co., Greene. 



* * Akenes more clavate, with scanty anstiform 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. Haeiia, Fisch. & Meyer, 1. c. 



B. macrantha, GRAY. 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. chrysostoma, var. macrantha, Gray, Proc. Am. 

 Acad. ix. 196, & Bot. Calif. 1. c. Burrielia chrysostoma, var. macrantha, Gray, Pacif. R. Rep. 

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

 Bigelow, Bofancler. 



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 paleae, little shorter than the akeue. Coast of Mendocino Co., 

 Bolander, Prinale. 



B. Chrysostoma, FISCH. & MEYER, 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. v. 254; Gray, Bot. Calif, i. 375, excl. var. Bur-
