gle series, often tortuous or somewhat plumose-penicillate, about the length
of the involucre ; of the fertile plant in one or several series, not thickened or
penicillate at the apex, usually much longer than the involucre.—Shrubs,
very rarely herbs (nearly all American), commonly glabrous and resinous, or
viscous. Leaves mostly alternate, entire or toothed, often decurrent on the
branches, forming either a foliaceous wing or narrow margins. Flowers
mostly white.

the low country of the Southern States! “ growing indiscriminately in
fresh or brackish soils,” Ell. Sept.-Oct.—Shrub 6-12 feet high. Pappus
of the fertile flowers very long and slender.
3. B. glomerulijlora (Pers.): shrubby, very glabrous; the branches angled;
leaves smooth, cuneate-obovate, attenuate into a short petiole, obtuse,
coarsely toothed ; the uppermost obovate-oblong, entire; heads sessile and
crowded in the axils of the leaves; the sterile involucre campanulate, with

Leaves pale green. Pappus of the fertile flowers very long, as in the preceding.—
De Candolle, from whom we have taken the characters of this species
and B. halimifolia, places the two at considerable distance from each
other ; and authors appear to have no doubt of their distinctness : but, if indeed
we are truly acquainted with the present species, we cannot distinguish
them.
4. B. salicina: “ shrubby, smooth ; branches angular; leaves mostly oblong
lanceolate, subdenticulate; the uppermost nearly linear, entire, viscid ;
heads sessile, clustered ; involucre ovate, as well as the smooth scales.”
Nutt, in Irons. Amer. phil. soc. (n. ser.) 7. p. 337, under the name of B. sa-
licifolia, which is pre-occupied by Persoon. B. afF. rupicpla, Torr.! in
ann. lyc. New York, 2. p . 211.
Banks of the Arkansas.—Nearly allied to B. glomeruliflora. More or less
resinously punctate. Leaves very obscurely 3-nerved, attenuated into a petiole.
Nuttall.—Dr. James collected this plant on the Canadian, but his specimens
are not sufficient to allow of our offering any opinion respecting the
species.

5. B. consanguinea (DC.): shrubby, much branched, glabrous, viscous
when young; the branchlets decurrent-angled; leaves sessile, obovate-cunei-
form, obtuse, with 2-4 rigid acute teeth on each side; heads sessile at the
summit of the branches and branchlets, solitary, or mostly aggregated in
glomerules of 2-4 ; scales of the involucre in the fertile heads oblong-linear,
obtuse, with a membranaceous somewhat fimbriate margin ; the innermost
rather acute. DC, prodr. 5. p. 408; Hook. &f Am . hot. Beechey, suppl.
p. 352. B. glomeruliflora, Hook. 8^ Am . l.c. p. 147, excl. var. /?. (which
these authors now refer to B. pilularis.)
California, Menzies, Douglas, &c.—Leaves 6 lines long, about 3 broad,
^lightly scaly above, DC.—Hooker & Arnott still doubt whether this species
be really distinct from B. glomeruliflora, or from B. pilularis.
_ 6. B. pilularis (DC.) : somewhat shrubby, much branched, glabrous and
viscous; the branches angled ; leaves sessile, obovate-cuneiform, obtuse, entire,
or often slightly toothed, 1-nerved, coriaceous; heads globose, solitary at
the summit of the branches on the axillary branchlets, bracteate with minute
leaves ; scales of the involucre in the sterile plant oblong, rather acute,
the margin membranaceous and somewhat fimbrillate at the apex. DC.

California, Douglas, Nuttall!—Leaves 4 lines long, and 2-3 broad; the
uppermost shorter than the heads. Heads about 2 lines in diameter. Fertile
plant unknown. DC.—“ In my specimens of the fertile plant, the leaves are
often strongly denticulate, three-fourths of an inch long, by half an inch in
width : the capituli solitary or by three's^ . . . Achenia smooth with 10
grooves, the pappus of moderate length. A shrub 3 or 4 feet high. It appears
to be subject to the attack of some insect, which causes excrescences on
the branches ; and hence, I suppose, arises the specific name.” Nutt. 1. c.
7. B. Douglasii (DC.): herbaceous, erect, very glabrous, viscid; stem
simple, angled above; leaves' on short petioles, lanceolate, acute, entire,
3-nerved, both sides punctate ; corymb in the sterile plant compound, somewhat
naked, fastigiate, bearing numerous heads; involucre campanulate;
the scales lanceolate, rather acute, with membranaceous ciliate margins.
(Leaves 2 inches long, 5-6 lines wide, the upper narrower; pappus of the
sterile flowers whitish, as long as the involucre.) DC. prodr. 5. p. 400.

California, Chamisso, Capt. Beechey, Douglas, Nuttall!—This plant,
which Lessing and Nuttall take for B. Pingraea, Hooker and Arnott remark
that the^ are still unable to distinguish from the Chilian B. glutinosa.
8. B, viminea (DC.): shrubby, glabrous; branches terete, the branchlets
striate-nerved; leaves on short petioles, oblong-lanceolate, acute at each end,
slightly 3-nerved at the base, entire, or minutely denticulate at the apex ;
corymbs somewhat racemose, crowded, terminating the branchlets ; heads of
the sterile plant pedicellate ; the scales -of the involucre oval-lanceolate,
acute, membranaceous, ciliate. DC. prodr, 5. p. 400; Hook. &r. Am . l.c.
California, Douglas,—Fertile plant unknown. Leaves 12-14 lines long,
those of the branchlets short and scale-like. Pappus of the sterile flowers
