California, Douglas!—The Californian plant is said by Hooker & Ar-
nott to accord with their var. y. of the Chilian A. pinnatifida, which seems
to vary greatly in its foliage. The leaflets in this form are deeply pinnatifid,
with very narrow segments, and the upper part of the stem is almost
tomentose. The 5 calyx-segments are articulated with the. tube, thick and
coriaceous : the stamens are usually 3.

Calyx infundibuliform-campanulate, 10-striate, 5-toothed ; the teeth
colored, short and broad, mucronulate-acute, spreading ; the throat scarcely
contracted, furnished with 5 transverse oblong fleshy glands. Petals 5,
orbicular, scarcely unguiculate, spreading. Stamens 9-15, erect-spreading,
inflexed in (Estivation : filaments filiform : anthers roundish. Ovary obo-
vate, with a single or 2 collateral suspended ovules, obliquely truncate and
pubescent at the summit: style terminal or nearly so, flexuous, included :
stigma thickened,, obtuse. Achenium coriaceous, 1-seeded, included in the
indurated tube of the calyx.—A rigid glabrous evergreen shrub, with numerous
branches. Leaves sessile, densely fascicled, rigid, linear-acerose, with
minute scale-like stipules. Flowers small (white), clustered in short spikes,
which are disposed in compound dense terminal panicles; bracts numerous,
minute.

On the declivities of mountains, St. Barbara, St. Francisco, and Monterey,
California, Beechey, Douglas! Nuttall! 0. St. Diego, Nuttall! May.—
This singular shrub has somewhat the habit of Tamarix, as Mr. Nutta.ll
remarks. The rigid somewhat triangular leaves are about half an inch in
length (in var. 0. shorter), and are inclined to fall in dried specimens. Mr.
Nuttall proposes to form a distinct section or tribe for its reception (Adeno-
stomaceae, Nutt.) ; but we leave it for the present in Sanguisorbeae, with
which it has many points of resemblance : in foliage it is not unlike
Margyricarpus.
