31. A . Ca lijo rnica (Less.): shrubby, pubescent-canescent; leaves pin-
nately 5-7-divided, with very narrowly linear segments, which are rarely
2—3-cleft; the uppermost entire ; heads in a simple or compound raceme,
secund, nodding, on short pedicels, hemispherical; scales of the involucre
elliptical, obtuse, with broad scarious margins, almost glabrous; corolla
glabrous. L e s s , in Linneea, 6. p . 523 (whence the above character is derived)

California, Chamisso, C a p t. Beechey. At St. Barbara, N u tta ll', where it
is said to be common, to have much the appearance of A. Abrotanum, the
branches canescent, the heads large, and the receptacle somewhat hairy.—
De Candolle has omitted this species. Besser, who has recently examined
the original specimens (Linneea, l. c.), pronounces the plant a congener and
near ally of his A. Fischeriana, differing only in the division of the leaves.
He adds that the ovary is acutely 4-5-ribbed, one of the ribs winged, and
the rather large disk crowned with 4 or 5 short membranaceous squamellte.
32. A . F ische riana (Bess.): shrubby, subcanescent; lower leaves biter-
nately divided ; the upper 3-cleft; segments filiform; uppermost leaves entire
; heads racemose, secund, nodding, hemispherical; scales of the involucre
ovate-elliptical, with scarious margins ; corolla glabrous. B e ss. A b ro t., &•

“ St. Francisco, California.—Shrub 3 feet high, decumbent.” Besser, l. c.
who, under var. 0., remarks that the receptacle bears a dense wool, longer than
the involucre ; and that the acutely ribbed achenia are terminated by a membranaceous
and somewhat lobed pappus; the epigynous disk therefore large,
as in Tanacetum. Mr. Nuttall’s plant (not in flower) is from Monterey.
The leaves have smaller ones fascicled in the axils ; which is said by Lessing
to be the case in A. Californica.
