ADDITIONS TO COMPOSITjE.
LIATRIS, p. 67.
7 (a). L. Chapmanii: minutely cinereous-pubescent or nearly glabrous;
stem rigid, very leafy; leaves strongly punctate, linear, rather obtuse, tapering
to the base; the upper very short, the lowermost elongated ; spike vir<*ate,
dense; the nearly sessile heads closely appressed, longer than the bracts,'
mostly 3-flowered ; scales of the involucre (about 8), oblong, acute or mu-
cronulate, appressed, resinous-punctate, shorter than the pappus, the outer
very short; achenia villous-canescent; pappus rigid, plumose-barbellate
towards the base.
Sand hills of Middle Florida, Dr. Chapman! Sept.—Afoot or more in
height; the cauline leaves, except the lowest, seldom more than an inch
long, scarcely a line wide, broadest near the apex, usually spreading. Spike
4-10 inches long. Scales of the involucre often tinged with purple, obtuse
and mucronulate, or acute, the margins very slightly if at all scarious.
Flowers, and especially the pappus, large for the size of the heads; the latter
composed of about 30 stiff bristles, fully as long as in L. cylindracea, very
much longer than the achenia, densely barbellate towards the base, but
scarcely more than denticulate at the apex.—This well-marked species belongs
to the same subdivision as L. punctata, and has fully as large flowers;
but the pappus is scarcely more plumose than in L. secunda.
10. L. graminifolia, S. (L. dubia, Barton! 1. c.) Add syn. L.propinqua,
Hook. hot. mag. t. 2829.—If admitted as a species, the anterior name imposed'
by Barton must be retained.
EUPATORIUM, p. 81.
E . variifolium, Bartl. {lnd. sem. hort. Gatt. 1840; Linncea, 15, suppl.
p . 93) appears to be only a state of E. cannabinum, and to have been mistakenly
considered as of American origin.—A form of A. cannabinum was cultivated
in the Berlin Botanic Garden in the year 1839, under the erroneous
name of E. trifoliatum.
E . Engelmannianum, Link, proposed in hid. sem. hort. Berol. 1840, is
founded on a plant raised from seeds sent from this country by Dr. Engel-
mann: but we have not yet seen the description.
ASTER, p. 103.
10 (o). A. eryngiifolius: stem simple, hirsute, leafy to the summit, bearing
solitary or very few heads; leaves rigid, erect, glabrous, narrowly linear-
lanceolate, pungently acute, 1-3-nerved, with cartilaginous margins, sparsely
spinulose-serrate, or rarely entire; the radical attenuate at the base; the
upper successively shorter, partly clasping; scales of the hemispherical involucre
numerous, nearly equal, lanceolate, foliaceous, rigid, with mucronate
or cuspidate mostly squarrose tips; rays numerous (white!); achenia glabrous.—
Prionopsis? Chapmanii, of this work, p. 245.
As the rays of this plant prove to be white instead of yellow, we now re-
move it to its proper station next to Aster paludosus, with which it well ac-
cords in aspect, in the pappus, &c .; and from which its somewhat spinulose
leaves and white rays abundantly distinguish it.
14. A. adscendens (Lindl.)—Wind River Chain of the Rocky Mountains,
above 7000 feet, Lieut. Fremont! Var. a, and
6. Fremontii: stem leafy, simple, bearing one or two heads; leaves thin;
the cauline mostly oblong-lanceolate ; exterior herbaceous; scales of the involucre
loose (either numerous or few); the inner very narrowly linear, acute;
pappus white.—A span high: perhaps a distinct species, connecting the
Amelli with the Alpigenous Asters.
38. A. ericoides, 0. villosus. Add syn. A. pauciflorus, Martens! in hull,
acad. Brux. 8 (1841), p. 67.—The A. ericoides, Schkuhr, handb. t. 245, is
a good representation of A. multiflorus.
71 (a). A. anomalus (Engelmann! mss.): more or less cinereous-pubescent;
stem simple or racemosely branched above, the branches erect-spreading;
leaves ovate or ovate-lanceolate, entire, acumiate; the radical and cauline
cordate, on slender naked petioles (rarely somewhat serrate); those of the
flowering branches lanceolate, subsessile; scales of the hemispherical involucre
numerous, imbricated in several series, appressed at the base, with
linear elongated and squarrose tips; achenia glabrous.
On limestone rocks, the brink of precipices, &c., in Illinois and Missouri,
not uncommon, Dr. Engelmann ! Sept.-Oct.—A most remarkable species,
with nearly the foliage of Aster Shortii; while the heads and involucre much
resemble those of A. oblongifolius, being equally squarrose, but rather smaller,
and scarcely glandular or granular.
79. A. reticulatus (Pursh) should doubtless be stricken out, and the synonym
referred to Diplopappus obovatus,-p. 184.
106. A. glacialis (Nutt.)—Defiles of the Wind River Chain of the
Rocky Mountains, and also just below the snow-line, Lieut. Fremont!__The
latter specimens are only about two inches high, more pubescent; the leaves
chiefly radical, short, and spatulate; and the involucre quite villous in a
young state.—With the above, Lieut. Fremont also collected a specimen of
A. Andinus, Nutt., A. integrifolius, Nutt., Sfc.
107. A . salsuginosus (Richards.)—Wind River Chain of the Rocky
Mountains, above 7000 feet, Lieut. Fremont! Both var. a. Sf 0. (Leaves
varying from linear-lanceolate to spatulate-oblong : rays showy, violet-
purple), and,
y. scaposus : ctespitose, dwarf; scape slightly exceeding the obovate-
oblong radical leaves, naked, or with a few bracts, bearing a single head.—
Probably gathered near the snow-line.
110. A. graminifolius (Pursh).—New Hampshire, Mr. Eddy ! in herb.
Tuckerman.
116. A . (Orthomeris) glaucus.—Wind River Chain of the Rocky Mountains,
at the elevation of 7000 feet or more, Lieut. Fremont!—A close congener
of A. elegans (of which Lieut. Fremont gathered a single specimen
near the same locality !): rays several, small: achenia slightly’hairy.
121. M. (Oxytripolium) angustus— Saline swampy margin of the Lake
of the Woods, and of Devil’s Lake, Mr. Nicollet!
SOLIDAGO, p. 195.
23. S. humilis, 0.—Abundant in the Notch of the White Mountains of
New Hampshire 1 (where it was first collected by Mr. Tuckerman !) Near
the Willey house, several specimens of this plant, and also of S. altissima,
were collected with greenish-white or cream-colored rays 1
