Rocks along rivers, and on dry prairies, from the upper Mississippi! and
Missouri! to Arkansas! Kentucky! and Illinois ! Sept.-Oct.—Stems numerous
from the same root, often suffruticose at the base, rigid, erect or
ascending, much branched, 1-2 feet high, somewhat hirsute or nearly glabrous
below: the branches, young leaves, and involucre covered, more or
less abundantly, with minute resinous and somewhat viscid granules, on
which account the plant exhales a heavy odor. Leaves 1 to 2 inches long,
varying from 2 to 5 lines in breadth, often nearly linear, abruptly acute or
mucronate, pale, rather rigid, reticulated, more or less scabrous with minute
strigose hairs, particularly on the margins which are sometimes scabrous-
ciliate; the upper ones more manifestly sprinkled with reginous dots, which
are frequently pedicellate, so as to appear like glandular hairs ; those of the
branchlets small, often crowded, gradually passing into the scales of the
involucre. Heads very numerous, scarcely as large as in A. Carolinianus;
the scales of the involucre with more or less prolonged foliaceous summits,
which are squarrose-spreading or at length reflexed; all equal iii length, or
the exterior somewhat shorter. Rays purple or violet. Achenia canescent
with a fine closely appressed pubescence. Pappus brownish.—The numerous
specimens before us afford no characters to distinguish the A. graveolens
from the A. oblongifolius-of Nuttail.
69. A . amethystinus (Nutt.): hirsute with a close somewhat cinereous
pubescence ; stem racemose-paniculate; leaves nnmerous, linear-lanceolate,
entire ; strigose-scabrous, acute, partly clasping by a dilated or auriculate
base; scales of the involucre somewhat equal, not glandular or viscid, linear,
acute, erect, with squarrose foliaceous tips; achenia silky.—Nutt. ! in trans.
Amer. phil. soc. (n. ser.) 7. p. 294.
Near Boston and Salem, Massachusetts, Nuttail! Mr. Little! Sept. ?—
We have only seen branches; with leaves about an inch long, abont 2 lines
wide, thickish, minutely reticulated, pale, strigose under a lens: the numerous
racemose branchlets are furnished with similar leaves of a smaller
size, and bear one to three or four heads, scarcely half the size of those of
A. Novae-Anglite. Involucre about the length of the disk ; the scales minutely
strigose; the exterior slightly spatulate, the lower whitish portion somewhat
narrowed ; the innermost rather longer and more attenuated. Rays
numerous, azure according to Nuttail, appearing violet in dried specimens.
Pappus turning brownish.—Resembles A. oblongifolius.
t t Scales of the involucre loose, very narrow (glandular-viscid), appearing as if
nearly in a single series.
70. A . Nova-Anglia (Linn.): stem stout, hispid, corymbose at the summit;
the branchlets and involucre somewhat viscid ; leaves very numerous,
lanceolate or lanceolate-linear, auriculate-clasping, entire, acute, clothed with
a close somewhat scabrous pubescence; scales of the involucre narrowly
subulate-linear, lax, equal, as long as the disk; achenia villous-hirsute.—

Low or moist grounds, Canada and Northern States ! to Missouri ! Kentucky
! and the upper districts of the Southern States! Sept.-Oct.—Stem
3-8 feet high, mostly purple, hirsute with spreading sharp jointed hairs; the
summit and branches furnished besides with a more or less copious close
granular-viscid pubescence, which also clothes the pedicels and the involucre,
and exhales a faint resinous odor. Leaves 2-4 inches long, about half
an inch wide, finely reticulate-veined, often somewhat 3-nerved ; the lower
more obtuse; those of the flowering branches often tinged with purple, like
the involucre. Heads in a short thyrsus or corymb, or in compound somewhat
paniculate corymbs, often an inch and a half in diameter, including the
large and very numerous violet-purple rays; the latter sometimes rose-color
in cultivation (A. roseus, Desf. cat. hort. Par. ) ; the disk turning slightly
purplish. Scales of the involucre numerous in 2-3 series, but similar in
size and form, lax, and very narrow, so that the involucre appears nearly as
simple as an Alpigenous Aster, attenuate from the short chartaceous appressed
base to the apex; or the outermost almost entirely foliaceous.—A
handsome and well-known species, of very uniform appearance in its native
situations, but several varieties have resulted from long cultivation in the
European gardens. To this, or to A. puniceus, probably belongs the A. con-
cinnus, Colla, hort. Ripul. appx. 3, in act. acad. Tur. 33. p . 134, t. 12,
which De Candolle has incautiously cited under A. concinnus, Willd.
71. A. modestus (Lindl.): stem glabrous below', the summit and the peduncles,
or branches of the simple corymb, glandular-pubescent; leaves numerous,
lanceolate, acuminate, sparingly and sharply serrate, glabrous, partly
clasping; scales of the involucre linear-lanceolate, acute, lax, equal, about
the length of the disk; achenia pubescent.—Lindl. ! in Hook. jl. Bor.-Am.

Mountain woods at the mouth of Smoking River, lat. 56° (near the Rocky
Mountains), Drummond! j8. Forests of the Rocky Mountains (lat. 42° ?), and
plains of the Oregon, Nuttail!—Stem about a foot high, simple. Leaves
about 3 inches long, less than an inch wide, serrate with small often spreading
teeth; the uppermost clasping by a broad base; the lower somewhat
narrowed at the base and less clasping. Heads few, resembling those of A.
Novae-Angliae ; the scales of the involucre fewer and rather broader, somewhat
glandular. “ Rays pale blue,” Nutt. Achenia 10-ribbed, pubescent,
especially on the ribs, both in a. and /?., which differ very slightly.
*** Several insufficient specimens of undetermined species remain in our collections,
or in those submitted to our examination: we think it better to leave them
unnoticed than to, describe from imperfect materials, which is very hazardous in
such a genus as the present.
X Species unknown to us, founded on native specimens.
72. A . ccerulescens (DC.): stem erect, smooth; branches erect, leafy,
racemose; leaves sessile, about half-clasping, broadly linear or lingulate,
acute somewhat coriaceous, entire, almost smooth, the margins and midrib
beneath scabrous; those of the branchlets (which bear single heads) gradually
passing into the oblong acute loosely imbricated and slightly squarrose
scales of the involucre. DC', prodr. 5. p . 235.
Texas, in the eastern districts, Berlandier.—Cauline leaves 3 to 4 inches
long, 4 lines broad. Heads as large as in A. puniceus ; the rays pale-blue.
Achenia almost glabrous. Pappus reddish-brown, DC.—The species is
placed next to A. puniceus.
