1. B. artemisicefolia (Less.): leaves crowded, mostly alternate, nearly glabrous

woolly, oblong; rays small, oval; achenia minutely hispid along the angles ;
scales of the pappus mostly 8, obtuse; four of them (corresponding to the
angles of the acheniuni) linear, the others oblong and rather shorter.—Less, in

California, Menzies, Chamisso, Douglas! Nuttall! &c.—A low shrub.
Heads on distinct peduncles when the compact corymbs are simple, but often
somewhat fascicled and sessile.—Without much doubt theB. stcechadifolia /?.
Californica of De Candolle is a state of his B. artemisicefolia /3. Douglasii;
but we have not the means of satisfying ourselves whether the latter has been
correctly united with the B. arte mi si® folia of Lessing, which is said to have
sessile or slightly pedicillate heads, only two and a half lines in length. 2
2. B. confertiflora (DC.): stem and branches densely arenose-tomentose
or woolly ; leaves alternate, cauescently tomentose beneath, pinnately 5-7-
parted, with narrowly linear segments, or often 3-parted, with the middle division
3-toothed at the apex; heads (small) in dense corymbs ; scales of the
ovoid involucre (about 5) obovate, retuse, woolly-canescent; rays 3-4,
small, neatly orbicular; achenia slightly scabrous-pubescent; scales of the
pappus 8- 10, oblong, denticulate, nearly equal.—D C .! prodr. 5. p. 657;

California, Douglas ! Nuttall! April.—Plant shrubby at the base, about
a foot high. Lower divisions of the leaves largest. Heads clustered, but on
distinct peduncles when in fruit. Involucre about two lines long.
3. B. trifida (Nutt.): stem and involucre closely arenose-woolly when
young; leaves alternate, cuneate-oblong, closely sessile and partly clasping,
loosely tomentose beneath, 3-cleft at the apex; heads (small) in crowded
corymbs; scales of the obovoid involucre 5, broadly obovate; rays 4-5,
broadly oval, small; achenia glabrous, or slightly hairy along the angles;
scales of the pappus 10-14, equal, oblong, obtuse, nearly entire.—Nutt. ! in

St. Barbara, California, Nuttall! April.—Growing with the preceding;
the heads about the same size. Leaves very numerous, about half an inch
long, nearly glabrous above.
4. B. achillceoides (DC.): woolly-tomentose throughout; leaves alternate,
cuneiform, with a long attenuate base, bipinnatifid above; the lobes (2-4
pairs) small, entire or toothed; heads (rather large) solitary, terminating the
sparingly corymbose branches or peduncles; scales of the globose very woolly
involucre about 10, ovate-lanceolate, acute; rays 8- 10, oblong; achenia
hairy on the angles; scales oval or oblong, somewhat unequal, laciniate-
toothed at the apex.—DC.! prodr. 5.p. 637.
California, Douglas !—Suffruticose, branched from the base. Leaves less
than an inch long, laciniate-bipinnatifid. Heads not clustered. Rays 3-4
lines long.
* * Herbaceous: heads solitary on naked, simple peduncles.
5. B. lanata (Nutt.): stems mostly branched from the decumbent base,
lanuginous-tomentose; leaves lanuginous-tomentose beneath, alternate, or
the lower opposite, pinnatifid ; the uppermost often linear and entire ; heads
(large for the genus) on naked peduncles ; rays large ; achenia glabrous.—

Oregon, common from the Rocky Mountains to the Coast! (The B. tenuifolia,
DC. was probably collected in Oregon instead of California.)—Stems
10-15 inches high, frequently branched above, with the peduncles somewhat
corymbose. Segments of the leaves 1-3 pairs. Involucre subglobose, composed,
as in the following species, of about 12 oval or oblong connivent scales,
wbich.are all clothed with a dense and intricate wool. Scales of the pappus
oblong and obtuse, somewhat unequal, denticulate at the apex, often a little
united at the base.
6. B. leucophylla (DC.): lanuginous-tomentose throughout; stems branched
