mont!—Two states were collected ; the one connecting this variety with var.
minuta and var. alpina; the other larger, with a stout glabrous stem.
25. S. thyrsoidea.—Abundant in woods from the base of the Notch to the
alpine region of the White Mountains of New Hampshire, and also sparingly
found on the exposed alpine summits, far above the limit of trees! Also
Indian Pass, and sides of Mount Marcy, Northern New York, Mr. Macrae!
Plant 1-3 feet high, mostly with an elongated virgate or thyrsoid leafy raceme.—
Add syn. S. Yirgaurea, Pursh! fl. 2. p. 542. (Labrador, Kohl-
meister !)
26. S. glomerata (Michx.).—Our plant is certainly the species of Michaux,
the specimen of his herbarium having been compared with ours by Mr.
Decaisne. The state with a strict glomerate inflorescence, as described by
Michaux, has recently been collected on the Black Mountain, North Carolina,
by Mr. Buckley.
31. S. RiddeUii.—Add syn. S. amplexicaulis, Martens! in lull. acad.
Brux. 8 (1841), p. 66.
39. S. neglecta, is not found in N- Carolina; the specimens received from
thence prove to have been collected in Massachusetts. It extends northward
to Montreal, Mr. Macrae !
40. S. patula.—The phrase ‘ leaves very scabrous above,' was accidentally
omitted in the specific character.
49. iS. amplexicaulis.—The reference to Martens under this remarkable
species must be erased, his S. amplexicaulis being S. Riddellii, as above
noted.
SILPHIUM, p . 274.
3. S. pinnatijidum (Ell.) must be reduced to a variety (/l. pinnatijidum)
of S. terebinthinaceum; Mr. Sullivant having noticed that they pass into
each other, as we suspected, like the varying forms of S. compositum. In
specimens from Alabama, collected by Mr. Buckley, the leaves vary from
sinuate-toothed to somewhat bipinnatifid.
IVA, p. 286.
4. I. microcephala.—Middle Florida, Dr. Chapman!—Heads larger than
in the original description, 6- 8-flowered. Leaves filiform-linear, often an
inch long, with smaller ones fascicled in their axils, punctate, and, like the
branches, Sec. sparsely strigose with minute hairs.
HELIANTHUS, p. 318.
13. H. ocddentalis (Riddell).—Add var.
y. Dowellianus: nearly smooth and glabrous; stem often stout (2-5 feet
high) and more leafy, simple or corymbose-paniculate at the summit; leaves
larger, varying from broadly ovate, or even slightly cordate, to oval-oblong.—
H. Dowellianus, M. A . Curtis! in Sill. jour. 44. p. 82.
Around Franklin, Macon County, North Carolina, Mr. Curtis! Mr.
Buckley ! with var. /?., which connects it to the ordinary state of the species.
—Limb of the lower leaves 3-6 inches in length, 2-5 broad, rather coriaceous,
in outline, See., resembling those of some forms of H. atrorubens.
Heads and flowers as in the ordinary form of the species.
