succulent, smooth, linear-oblong, incisely toothed ; head subsessile, solitary;
scales of the involucre linear, obtuse, softly pubescent; rays very small, 2—3-

St. Diego, California, N u t ta l l ! on the sands of the sea-coast. May.—
Plant 3—4 inches high. Lower leaves oblong-spatulate, the coarse teeth obtuse.
Rays scarcely if at all exserted. Pappus as long as the corolla of the
disk, whitish.
4. L . e leg an s (Nutt.) : stem decumbent, somewhat hirsute, much branched
from the base ; leaves sparsely hispid, linear-lanceolate ; the radical pinnati-
fid , the cauline laciniate-toothed towards the apex, the uppermost entire ;
peduncles and involucre somewhat villous and glandular; rays 10-12, 3-4-
toothed, longer than the disk ; pappus white.—N u t t . ! 1. c., under Madaroglossa.
St. Barbara, California, N u tta ll!—Awns of the pappus more densely plumose
towards the base than in L. heterotricha, the long and very fine
woolly hairs crisped and interlaced ; and the yellow rays are smaller than in
that species. It appears to differ from L. hieracioides by its larger deeply
toothed rays, very woolly white pappus, &c.

. ^• L . heterotricha (Hook. Sc Arn.! 1. c .) : stem branching; the upper por-
lion» and the oblong-linear obtuse entire or denticulate leaves somewhat seabrous,
with a short pubescence, and with stipitate black glands intermixed ;
rays (white ?) 10-12, large, 3-cleft at the apex, twice the length of the disk;
pappus very white.—Madaroglossa heterotricha, DC. ! 1. c .; Hook. ! ic.

California, Douglas !—Plant 1-2 feet high. Leaves 1-2 inches long, 2-3

Callichroa & Calliglossa, Hook. <p Am.
Heads many-flowered ; the ray-flowers 10-15, ligulate, 2-3-toothed, pistillate
; those of the disk tubular, perfect. Scales of the involucre oblong or
lanceolate, nearly in a single series, foliaceous; the base convolute and enclosing
the ray-achenia. Receptacle flat, chaffy at the margin only, or
throughout. Corolla of the disk with a short pubescent tube and an infundi-
buliform throat, 5-toothed. Branches of the style subulate-filiform, hairy
above, at length exserted and recurved. Achenia of the ray glabrous,
narrowly obovate-oblong, obcompressed, somewhat incurved, crowned
with a small protuberant disk, destitute of pappus; of the disk villous,
obcompressed, subclavate or narrowly cuneiform-oblong, with a pappus
of 12 to 25 subulate and naked serrulate-scabrous awns.—Annual (Californian)
herbs, with entirely the habit and aspect of Layia and Oxyura.
Flowers yellow; the rays often whitish at the apex. Anthers purplish-
brown. ,
The first section is. only distinguished from Layia by the naked, instead of plumose
awns of the pappus, and might perhaps be combined with it.
§ 1. Receptacle naked and pubescent at the centre, chaffy at the margin in one
or tnore series ; the exterior resembling the scales of the involucre : achenia
narrow: aims of the pappus (20-25) setiform, equal.—C a l l i c h r o a , Fisch.
& Meyer.
1. C. platyglossa (Fisch. & Meyer, 1. c .) : somewhat hirsute with slender
white hairs, and cinereous with a short pubescence, with small stipitate glands
intermixed ; leaves linear-lanceolate ; the lower incisely pinnatifid, the upper
entire or slightly toothed ;, achenia of the disk slender, slightly obcompressed,
villous, when mature rather longer than the pappus ; corolla somewhat pubescent.—

California, at the Russian Colony Ross, Fisch. Sp Meyer, and at St. Barbara
and Monterey, Nuttall!—Plant branching from the base, 6-12 inches
high. Heads showy, an inch and a half in diameter, including the light
bright yellow cuneiform-oblong rays ; the latter whitish at the tips in the wild
plant, according to Nuttall.—The small and stipitate dark glands are not mentioned
in the account of the cultivated plant; with which Mr. Nuttall’s specimens
otherwise well accord.
