or the lowest sparingly laciniate-toothed : scales of the involucre and short orbicular 

 rays 6 to 8 : akenes minutely hairy : pappus of 3 to 5 stout awns and at least twice 

 as many small and narrow laciniate chatty scales. - Burrielia maritima, Gray, Proc. 

 Am. Acad. vii. 358. 



On the Farallones, rocky islets off San Francisco, Mr. Gruber. The rays in the specimen do 

 not exceed the disk, but, being broad and flat, probably they may become more conspicuous. 



7. B. Fremontii, Gray, 1. c. Slender, a span high, somewhat hirsute-pubes- 

 cent : leaves narrowly linear and entire, or with 2 to 5 very narrowly linear lobes : 

 scales of the involucre and rather short oval rays 10 to 12 : disk-corollas slender and 

 with a long narrow tube : pappus of mostly 4 slender awns, and as many or twice 

 as many short linear or oblong and entire or 2-cleft blunt scales, or sometimes want- 

 ing. Dichceta Fremontii, Torr. in PI. Fendl. 102. Burrielia (Dichceta} Fremontii, 

 Benth. PL Hartw. 317, a state (always 1 ?) without pappus. 



Valley of the Sacramento (Fremont, Hartwcg) and near Vallejo, Greene. Ovaries minutely 

 pubescent, or, in the form from Hartweg, without pappus, glabrous except at the summit. Upper 

 leaves inclined to be dilated below, and to have 3 to 5 palmately-disposed lobes. 



8. B. uliginosa, Gray, 1. c. Diffuse, at length decumbent, a span to a foot high, 

 loosely pubescent with somewhat cobwebby hairs : lower or most of the leaves 

 copiously pinnatifid from a broad or broadish rhachis ; the lobes narrowly linear : 

 scales of the involucre and oblong exserted rays usually 10 to 13 : throat of disk- 

 corollas very broad, and narrow tube rather short : pappus of 2 or 3 stout chatty- 

 subulate awns, and as many or twice as many intervening conspicuous and broad 

 truncate and laciniate-fimbriate scales. Dichceta uliginosa, Nutt. 1. c. 



Var. tenella, Gray, 1. c. (Dichceta tenella, Nutt. 1. c.), is only a depauperate 

 state, on drier soil, with narrow linear leaves, and more of them entire ; the rays and 

 involucral scales reduced to 8 or 9, or rarely to 5 or 6. 



Low- grounds, common through the western part of the State. Very variable. Leaves in the 

 larger plants a span long, and the sterns luxuriant in proportion. Akenes a line long, oblong- 

 linear and a little narrowed downward, sometimes pubescent, sometimes glabrous, apparently in 

 plants growing together.

Head many-flowered, with few or numerous pistillate rays ; all the flowers fertile. 

 Involucre campanulate, of a single series of oblong or lanceolate thin-herbaceous 

 scales, which become concave or involute and embrace more or less the ray-akenes. 

 Receptacle naked, convex or conical, or in an ambiguous species flat. Rays oval or 

 oblong, 2 3-toothed : disk-corollas with narrow tube and campanulate 5-lobed 

 limb. Anthers tipped with an abrupt narrowish or very slender appendage. Style- 

 branches with a truncate-capitate (or rarely conical) tip. Akenes linear and mostly 

 tapering to the base, or linear-cuneate ; those of the ray commonly somewhat in- 

 curved. Pappus a series of chaffy scales or squamellae (either few or numerous), 

 which are either pointless or extended into an awn, or sometimes none. Low and 

 diffuse or depressed annuals, all of the Californian region, mostly woolly, in one 

 section glandular ; with opposite or alternate commonly toothed or pinnately-parted 

 leaves, and small or proportionally rather large heads terminating the branches. 

 Flowers all yellow, or the rays occasionally white or rose-color. Gray in Proc. 

 Am. Acad. ix. 197. 



A rather well-marked genus, as rightly characterized on the original species by Torrey and 

 Gray, now happily extended by Bentham in the Genera Plantarum, and still more augmented in 

 the paper referred to above. The section placed foremost resembles Bceria, section Dichceta, from 

 which it is distinguished by the partial enclosure of the ray-akenes in the scales of the involucre.
