AND GENERA OF PLANTS. 393 



MADAROGLOSSA. (Decand.) 



Capitulum many-flowered, radiate; liguli feminine in a single series, the apex 

 trifid. Discal florets hermaphrodite, tubular, five-toothed, pubescent. Stig- 

 mas filiform, hirsute, acuminated, at length exserted. Receptacle naked, 

 villous, with a single row of paleae between the ray and disk. Involucrum 

 hemispherical, sepals lanceolate, in a single series, (eight to twelve,) the 

 base embracing the achenium, the summit free and foliaceous. Achenia 

 of the ray smooth, linear-oblong, externally convex, acute, almost stipitate 

 at base, without granulations, crowned with a circular, areolar cicatrice; 

 those of the disk numerous, villous, acutely conic and narrow, crowned with 

 a paleaceous-pilose, subscabrous pappus, simple, or plumose towards the 

 base, of eighteen to twenty-five setse. — Herbaceous, annual or biennial, usu- 

 ally hirsute plants, with alternate, pinnatifid, or incise, linear leaves; branches 

 one-flowered, fastigiate, the apex naked or pedicellate. Flowers yellow, or 

 parti-coloured yellow and white in the ray, disk yellow; anthers dark brown. 



Madaroglossa * elegans; decumbent, somewhat hirsute, much branched from 

 the base; radical leaves pinnatifid, linear-lanceolate; stem leaves amplexicaule, 

 incise, the uppermost entire; pedicels somewhat glandular and villous; rays 

 ten to twelve, (apparently) of one colour; receptacle villous; pappus of eighteen 

 to twenty setae, densely plumose towards the base. 



Hab, St. Barbara, Upper California. Nearly allied to M. heterotricha; but in that species the 

 leaves are entire. 



Madaroglossa ^carnosa; Q, stem decumbent, pilose towards the summit, as 

 well as the involucrum; leaves linear-oblong, succulent and smooth, incisely 

 dentate; capituli subsessile, solitary; sepals linear, obtuse, softly pubescent; 

 rays very small; achenia pubescent in both ray and disk; pappus loosely plu- 

 mose, of about eighteen to twenty setse. 



Hab. St. Diego, Upper California. A dwarf, inconspicuous flowered species, three or four 

 inches high, with thick, somewhat succulent leaves. Rays two or three-toothed, minute. Sepals 

 about twenty, in two series; the rays between the two series, with the achenium included in the 

 sepals, and without pappus. Achenium linear, villous, attenuated at base, subquadrangular. An- 

 thers with black, acute, linear cusps. Stigmas hirsute, subulate, a little exserted, spreading. Pappus 

 VII. — 4 Y
