sterile. Bracts of the subglobose involucre as many as the rays, 
carinate-complicate and enclosing the achenes. Receptacle some 
what convex, naked and smooth except the margin which is 
furnished with a single series of more or less united chaffy scales 
between the ray- and disk-flowers. Branches of the style in the 
disk-flowers subulate, very acute, minutely hispid. Achenes of 
the ray oblong, ohcompressed, somewhat incurved, glabrous, with- 
out lateral nerves or angles, crowned with a small sessile disk, 
destitute of pappus; of the disk obovate, with a pappus of 5-8 
small fimbriate-lacerate membranaceous scales. . 
A. madioides Nutt 1. c. Madia Nuttallii Gray. Stems slender, 1-3 
feet high, pubescent with white spreading hairs, glandular and paniculate- 
ly branched above: leaves linear-lanceolate, 2-8 inches long, remotely ser- 
rate, all but the lowest opposite: heads not very numerous, slender-pedun- 
cled, about 4 lines high: bracts of the involucre 8-12, with short incon- 
spicuous tips, densely glandular and hispid: rays 8-12, fan-shaped, deepli 
3-lobed, 4-6 lines long: achenes obovate-faleate, much compressed, wit 
their sides many-striate. Common on dry ridges in forests, Brit Columbia 
to California. 
45 MADARIA DC. Mem. Soc. Geney. vii, 280. 
Erect annuals with mostly opposite leaves and rather large 
heads of showy yellow-rayed vespertine flowers. - Heads many- 
flowered: the ray-flowers 10-20, ligulate, pistillate, in a single 
series: those of the disk tubular, perfect but sterile by the abortion 
of the ovary. Bracts of the subglobose involucre as many as the 
rays, complicate and enclosing their achenes, flattish on the back 
and with long somewhat spreading tips. Receptacle somewhat 
convex, fimbriate-hirsute except the margin which is furnished 
with 1 or 2 series of chaffy scales between the ray- and disk-flow- 
ers. Corollas pubescent or hairy at base, the rays very conspicu- 
ous but closingin sunshine. Achenes of the rays oblong-obovate, 
nearly straight, compressed, glabrous, without pappus. 
-M. elegans DC.1.c. Madia elegans Don. Stems stout, 1-6 feet high, 
ubescent with almost pilose spreading hairs, glandular above: leaves 
inear-lanceolate 2-4 inches long, usually more or a serrate, sessile, by a 
broad base, the lower crowded in a somewhat rosulate tuft, the others op- 
_ posite or scattered and becoming smaller upward: heads numerous, in an 
open cyme: bracts of the involucre hirsute, the linear tips nearly as long 
as the body: rays 12-20, 8-10 lines long, sharply 3-lobed, yellow. often with — 
a red or brown spot near the base: achenes rather thin and flat. On dry 
hillsides, western Oregon to California. 
M. corymbosa DC.1.c. Stems slender, 6-18 inches high, simple up to 
the inflorescence, pubescent with soft spreading hairs, glandular above: 
leaves linear, mostly opposite, remotely serrate, 1-4 inches long: heads 
rather few, in an open corymb; bracts of the involucre somewhat pilose 
and glandular, the linear tips not as long as the body. On dry hills and 
plaines, southern Oregon to California. Blooming early.
