the heads not larger than in E. coronopifolium. Corolla infundibuliform,
attenuate below, and abruptly dilated at the base; the teeth very short, ovate,
glandular externally. Pappus as long as the corolla. Achenia dotted with
scattered resinous globules.—Our plant appears to be that of Elliott, although
we have never seen the lower verticillate leaves, and the heads are mostly
7-9-flowered. The styles also in our specimens are often all included within
the corolla at every stage, and with short very obtuse lobes. Two or three
flowers of each head, however, often present the branches of the style elongated
and much exserted, as described by Elliott. The same thing occurs in
several of the succeeding species, and in Kuhnia eupatorioides, where the
style is usually included until a late period.
6. E . hyssopifolium (Linn.): stem minutely pubescent, simple or branched,
loosely corymbose at the summit; leaves opposite or verticillate, and often
fascicled in the axils, the uppermost alternate, linear or lanceolate, rather
obtuse, tapering or acute at the base, minutely pubescent, punctate on
both sides, 3-nerved, the upper ones 1-nerved, entire, the lower ones spar-
ingly toothed or serrate; heads 5-flowered; scales of the involucre 10, shorter
than the flowers, very pubescent, glandular; the outer ones short; the others
linear-oblong, obtuse, with slightly scarious margins; achenia glabrous and
usually glandular.—Linn. ! spec. 2. p . 836 (pi. Dill. Elth. Aj P lu k .! t. 88,

Cave, Kentucky,” Dr. Short!—Stem 1—3 feet high, usually very leafy.
Leaves commonly 3i —2 inches long, rather thick and rigid; the lateral nerves
somewhat anastomozing, approximate to the mid-nerve in the narrower
leaves, nearly wanting in the narrowest. Compound corymb rather loose,
often fastigiate. Corolla dilated at the base, as in numerous species, cyathi-
form or eampanulate at the summit; the lobes ovate, very short. Style
usually much exserted.—The Linnaean species was founded on the narrower-
leaved plant (E. linearifolium, DC.), in which the lower leaves are always
3-nerved, and often toothed; this passes insensibly into our var. y., the extreme
forms of which appear abundantly different, but Michaux has justly
united them. Our two varieties p. & S. taken by themselves, would never
be thought the same species, but we are unable to separate them.
7. E . leucolepis: stem mostly simple, puberulent; leaves opposite, divaricate,
lanceolate or linear, obtuse, closely sessile, serrate, very scabrous on
both sides, punctate, strongly 1-nerved ; the lower ones obscurely 3-nerved
or somewhat veiny ; corymb fastigiate, canescent; heads 5-flowered ; scales
of the involucre 8- 10, lanceolate, acute or acuminate, very pubescent and
glandular on the back, white and scarious at the summit, as long as the
flowers; achenia minutely glandular.—E. glaucescens/?. leucolepis, D C .!

Damp sandy soil, pine barrens of New Jersey! to Georgia! Florida!
Alabama! and Western Louisiana! Aug.-Oct. — Stem 2-3 feet high.
Leaves spreading or divaricate, rather rigid, perhaps never verticillate, seldom
fascicled in the axils, the uppermost rarely alternate, both surfaces of a
pale glauqous hue, the midrib prominent beneath; the lower ones 2 or rarely 3
inches in length, and from one-fourth to nearly half an inch wide, serrate
with appressed teeth; the upper narrower and more finely serrate, or
sometimes entire. Corolla, &c. nearly as in E. hyssopifolium. Appendages
of the anthers short, obtuse. Branches of the style exserted.—This has
sometimes been confounded with E. hyssopifolium, but is readily distinguished
as well by the leaves as by the very scarious and acute scales of the
involucre.
8. E . cuneifolium (Willd.): pubescent; stem simple or branching, loosely
corymbose at the summit; leaves very short, opposite, or the uppermost
frequently alternate, obovate-oblong, spatulate or oblong-lanceolate, acute or
attenuate at the base, slightly petioled, tripli-nerved or 3-nerved from the
base, pubescent and punctate on both surfaces, mostly obtuse, and with a
few obtuse serratures towards the apex; heads 5-flowered, somewhat crowded
on the loose tomentose branchlets of the corymb ; scales of the involucre
8- 10, very pubescent, sprinkled with glands, obtuse; achenia slightly glandular.—

Shady places, S. Carolina ! Georgia ! Alabama ! and Florida ! Aug.-
Sept.—Stem about 2 feet high, erect or ascending at the base. Leaves
about an inch long, of a pale glaucous hue on both sides, very obtuse, the
uppermost sometimes acute, entire and cuneiform at the base, usually with
2-4 obtuse teeth on each side towards the summit. Involucre, flowers,
pappus, &c. nearly as in E. hyssopifolium.
9. E.parvijlorum (E ll.): minutely velvety-pubescent, branching; leaves
opposite, or the lower sometimes ternate, and the upper frequently alternate
(sometimes verticillate, opposite, and alternate on the same specimen), lanceolate
or oblong, minutely punctate, tripli-nerved, somewhat reticulate-
veined, unequally and acutely serrate, usually entire below the middle,
tapering to the base, the lower slightly petioled ; corymbs numerous ; heads
(small) crowded, 5-flowered; scales of the involucre 8-10, in a double
series, pubescent and glandular; the exterior very short; the interior linear,
obtuse ; achenia glabrous or minutely glandular.—Ell. ! sk. 2. p . 299, (not

P- lancifolium: stem or branches strict, glabrous below, corymbose at the
summit; leaves opposite (sometimes ternate), lanceolate, rather rigid, almost
glabrous, acute, serrulate above the middle, tripli-nerved or 3-nerved ; the
nerves sparingly anastomozing.
i Damp soil, Virginia! to Georgia! Florida! Alabama! and Western Louisiana
! p. Louisiana, Dr. Leavenworth ! Louisiana and Texas, Drummond !
Aug.-Oct.—Stem 2-3 feet high, usually diffusely branched above. Leaves
paje, minutely velvety-pubescent beneath, 2-3 inches long, often an inch
wide, varying from scarcely acute to acuminate, sometimes serrate nearly to
the base ; the texture rather firm. Heads about as large as in E. coronopifolium,
crowded. Involucre shorter than the flowers.—In our var. p. the
leaves' are smaller, nearly glabrous, and rather narrowly lanceolate, resembling
the upper leaves of E. parviflorum, with which it agrees in other respects.
We had considered it a new species, but having observed various
intermediate states, we are satisfied that it is a mere variety of E. parviflorum.
The E. ambiguum of Hooker is said to have 8-10-flowered involu
