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 palew 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 ome 
base, of eighteen to twenty-five sete.—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 ye Ow, 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 ret and villous; rays 
ten to twelve, (apparently) of one colour; receptacle villous; pappus of PetieD 
to twenty sete, densely plumose towards the base. 
Has. St. Barbara, Upper California. Nearly allied to A. heterotricha; but in that species the 
leaves are entire. 
Madaroglossa * carnosa; ©, 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 sete. 
Has. St. Diego, Upper California. A dwarf, inconspicuous i Siireced 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-
