but two heads may occasionally become confluent, as happens in some other
species.

branched at the summit; leaves opposite, nearly sessile, lanceolate, somewhat
tapering to each end, conspicuously 3-nerved, pubescent, acutely and
rather remotely serrate above the middle; the uppermost often entire, and
sometimes alternate; corymbs numerous; heads glomerate, 5-flowered;
scales of the involucre about 10, linear-oblong, obtuse, pubescent or tomentose

que ! Sept.-Oct.—Stem 3-7 feet high. Leaves 3-4 inches long, resembling
some species of Solidago, minutely dotted, pubescent or sometimes almost
tomentose. Heads rather large. Lobes of the corolla ovate-lanceolate.
Style slightly enlarged and pubescent at the base ; the branches elongated
and thickened. Pappus somewhat remotely scabrous-serrulate.
1 1 . E . album (Linn.): stem pubescent, corymbose at the summit; leaves
opposite, sessile, broadly lanceolate, coarsely serrate-toothed, veiny, punctate,
more or less pubescent and scabrous; branches of the corymb fastigiate,
erect; heads 5-flowered, glomerate; scales of the involucre 10-14, closely

Sandy and barren fields, Pennsylvania and New Jersey ! to Florida ! and
Louisiana! Aug.-Oct.—Stem about 2 feet high, varying, as also the leaves,
from minutely pubescent to hirsute-villous. Leaves either narrowly or very
broadly lanceolate, often very deeply serrate; the veins reticulated beneath.
Involucre, corolla, and achenia, when old, copiously sprinkled with resinous
globules; in which state it is the E. glandulosum, Michx. Lobes of the
corolla ovate-lanceolate. Style more commonly included, but sometimes
manifestly exserted. Pappus densely barbellate-serrulate.
12. E . teucrifolium (Willd.): stem roughish-pubescent, corymbose at the
summit; leaves opposite (the uppermost very frequently alternate), sessile,
ovate-oblong and ovate-lanceolate, obtuse or truncate at the base, slightly
tripli-nerved, veiny, somewhat pubescent and scabrous, obscurely punctate,
coarsely serrate-toothed particularly towards the base; the uppermost nearly
entire; branches of the corymb few, often alternate; heads glomerate, 5-

acute ; the interior at length shorter than the flowers ; achenia glandular.—

Borders of swamps and thickets, Massachusetts! New Jersey! and Pennsylvania
! to Alabama ! and Louisiana! Aug.-Sept.—Stem 2-3 feet high,
rather slender. Leaves 2-4 inches long, variable as to the serratures, which
are often very coarse and irregular, sometimes even and more numerous;
ihe upper leaves small, usually lanceolate or deltoid-lanceolate, tapering
from the base to the apex, but usually rather obtuse, often entire, except a
few coarse teeth near the base, occasionally deeply incised. Corymbs small
and dense, often somewhat paniculate. Scales of the involucre with scarious
margins, little longer than the mature achenia.—The specific name of Will-
denow and that of Michaux were published during the same year (1803).
13. E . rotundifolium (Linn.): stem densely pubescent, corymbose at the
summit; leaves opposite, roundish-ovate, mostly obtuse, truncate or somewhat
cordate at the base, sessile, tripli-nerved, veiny, scabrous and pubescent,
pale or somewhat hoary and glandular beneath, deeply crenate-toothed;
corymb fastigiate; heads 5-flowered ; scales of the involucre 8-10, very pubescent,
glandular; the exterior very short; the interior linear-lanceolate, abruptly
acute or acuminate, scarcely shorter than the flowers; achenia glandular.—

14. E . pubescens (Muhl.): stem Very pubescent or somewhat hirsute,
corymbosely branched at the summit; leaves opposite, ovate, mostly acute,
slightly truncate at the base, sessile, somewhat tripli-nerved, veiny, more or
less pubescent, slightly scabrous, obscurely glandular-punctate, dentate-
serrate ; corymb fastigiate; heads 7-8-flowered ; scales of the involucre

Massachusetts! New Jersey! Pennsylvania, and probably in the Southern
States, in similar situations with the preceding. Aug.-Sept.—Stem 2-4 feet
high, usually a stouter and more branching plant than E. rotundifolium.
Leaves broadly ovate or ovate-oblong, 2-3 inches long and about 1J wide
near the base, rather obtusely and coarsely serrate ; the teeth (as in the preceding)
either simple and equal, or occasionally unequal, thus becoming
somewhat doubly serrate. Scales of the involucre with scarious summits.
Corolla, pappus, &c. as in E. rotundifolium, which it sometimes approaches
perhaps too closely; but the heads appear to be uniformly more than 5-
flowered.—The specimens in Willdenow’s herbarium (particularly fol. 2.)
certainly belong to this species; but that author states the heads to be 5-
flowered.
t t Leaves closely sessile or partly clasping at the base, or sometimes connate:
heads 10-20- (rarely 5-) flowered.
15. E . sessilifolium (Linn.) : glabrous; stem corymbosely branched above;
leaves opposite, closely sessile or partly clasping, distinct, rounded at the
base, lanceolate or ovate-lanceolate, tapering from near the base to the acuminate
apex, sharply serrate, veiny, obscurely punctate and paler beneath ;
corymb compound, pubescent; heads 5-flowered; scales of the involucre 10,
imbricated somewhat in a triple series, oval or oblong, obtuse, canescently
