Louisiana, D r . Leavenworth,! Missouri, M r . D u e rin c k ? (Also? Middle
Florida, D r . C h a pm a n !) Sept.-Oct.—A singular species (2-4 feet
high), very remarkable on account of its auriculate-amplexicaui leaves,
which are not unlike those of Aster prenanthoides, or A. patens v a r. phlogi-
fblius. Those of the stem are about 3 inches long, an inch and a half wide
in the middle, tapering to an acute apex, abruptly contracted below (the contracted
portion entire), and again much dilated at the insertion; this clasping
portion being either entire, or sharply serrate: the lowest leaves are similar,
except that the contracted portion is longer and narrower; while the upper,
gradually reduced in size and often entire, are less contracted below. Racemes
small, irregular. Heads small. Scales of the somewhat pubescent
involucre narrow, rather loose. We more commonly observe but a single
ray-flower.
50. S . b ra ch yph y lla (Chapman! mss.): stem scabrous-pubescent, often
virgately branched above, very leafy; leaves glabrous, with ciliate-scabrous
margins, obscurely veiny; the lowest oblong-spatulate, tapering into a short
margined petiole, appressed-serrate; the others oval or ovate, short, closely
sessile, often nearly entire; the secund racemes disposed in a virgate panicle;
scales of the involucre oblong, obtuse; achenia minutely canescent;
disk-flowers 5-6; rays none!
Middle Florida, in fertile soil, D r . C h a pm an ! D r . A le x a n d e r ! Georgia
& Alabama, B a ld w in ! L e Conte !—Stem 4-6 feet high, often much branched
above; the branches elongated, erect. Leaves pale beneath, somewhat
shining above; the lower about 3 inches long; the upper and those of the
branches an inch to half an inch in length, half an inch or less in breadth,
elliptical, ovate, or roundish, entire or sparingly serrate, sometimes mucronu-
late-acute, the lower surface rather obscurely reticulate-veined. Heads
about the size of those of S. altissima. Scales of the involucre glabrous, very
minutely ciliate; the exterior very short.—We find no rays in this well-
marked species; but some of the exterior flowers are occasionally destitute
of stamens.
51. S . E llio t t i i : smooth and glabrous throughout; leaves very numerous,
oblong-lanceolate or elliptical, mucronate-acute or somewhat acuminate, sessile,
veiny, the margins scabrousr serrate with small appressed teeth, the upper
often entire; heads in crowded recurved racemes, forming a pyramidal
panicle; scales of the involucre linear, obtuse; rays 8-10, scarcely longer
than the (5-7) disk-flowers; achenia minutely pubescent.—S. elliptical

simple, or sometimes branched above, the branches or summit angled; the
peduncles and pedicels more or less pubescent.—Allied to S.- pilosa, and
very similar in the inflorescence, heads, &c. but differs in the smooth stem
and leaves; the latter more veiny (the primary veins evident and often reticulated),
pale beneath, instead of green both sides, (2-3 inches long, an
inch or less in width, the upper smaller); the panicle perhaps more elongated;
and the scales of the involucre broader and more obtuse.
+ t + Leaves entire, or slightly serrate, the primary veins nearly obsolete; the minutely
pellucid-reticulate veinlets inconspicuous except by transmitted light:
heads small: scales of the 5-15-flowered involucre few, membranaceous, narrow.
52. S. pilosa (Walt.) : stem hirsute with spreading hairs, strict, often
branching above, very leafy; leaves oblong-lanceolate, serrulate, slightly
scabrous, mostly hairy along the midrib, often pubescent beneath, obscurely
veined ; the upper ovate-lanceolate or oblong, erect, closely sessile, mostly
entire; the recurved racemes disposed in a dense pyramidal panicle ; rays
7-10, scarcely longer than the about 5 disk-flowers ; achenia minutely pubescent.—

towards the summit, with whitish jointed hairs, often paniculately
branched at the summit | the branches or the numerous racemes recurved-
spreading. Leaves thickish or rather firm, pale green, closely sessile or
partly clasping, nearly veinless except by transmitted light, or sometimes
with the primary veins apparent; the prominent midrib, and often the scabrous
margins fringed with long hairs ; the surfaces often glabrous, but sometimes
scabrous-pubescent above and villous-pubescent beneath: lower leaves
2-3 inches long, lanceolate-oblong, sharply serrulate, mostly acute, often narrowed
at the base ; the upper gradually reduced to about half an inch m
length, 3-5 lines in width. Heads very numerous, about as large as m b.

subulate ; the inner linear. Pappus about as long as the corolla of the disk.
