Scorpiurus vermiculata.

Pod, or fruit, comparatively large. The interior grooves, or furrows,
are indistinct, or quite wanting: the exterior grooves are ten in
number, and well defined. Along the summit of these furrows are produced
numerous, small, pedicelled tubercles, quite similar to those of some
species of worms or caterpillars; and these small tufts, in connection
with the brownish-green color and peculiar coiling of the pods, make the
resemblance nearly perfect, especially if seen from a short distance.
The seeds are large, oblong, flattened at the ends, and of a yellowish
color. A well-developed fruit will measure about three-eighths of an
inch in diameter; and, when uncoiled, nearly an inch and a half in
length.

FURROWED CATERPILLAR.

Chenille rayee. _Vil._ Scorpiurus sulcata.

Fruit rather slender, furrowed, grayish-green within the furrows, and
brown along the summits. Four of the exterior furrows are surmounted
with numerous small, obtuse, or rounded tubercles; and the pods are
coiled in the manner peculiar to the class. The seeds resemble those of
the Prickly Caterpillar, but are of larger size.

PRICKLY CATERPILLAR. _Vil._

Small Caterpillar. Scorpiurus muricata.

Pod, or fruit, a fourth of an inch in diameter, curved or coiled;
longitudinally furrowed, with numerous, small, erect, tufted points,
regularly arranged along the surface. It is of a brownish-red color,
with shades of green; and, when well grown, bears a remarkable
resemblance to some species of hairy worms or caterpillars. The seeds
are large, long, wrinkled, and of a yellowish color.

VILLOUS OR HAIRY CATERPILLAR.

Chenille velue. _Vil._ Scorpiurus subvillosa.

This species resembles the Prickly Caterpillar, but is a little larger.
The most marked distinction, however, is in the small points, or
tubercles, placed along the longitudinal ridges, which in this species
are recurved, or bent at the tips. The seeds are larger than those of
the foregoing species.

CELERY.

Smallage. Apium graveolens.

Celery, or Smallage, is a hardy, umbelliferous, biennial plant, growing
naturally "by the sides of ditches and near the sea, where it rises with
wedge-shaped leaves and a furrowed stalk, producing greenish flowers in
August." Under cultivation, the leaves are pinnatifid, with triangular
leaflets; the leaf-stems are large, rounded, grooved, succulent, and
solid or hollow according to
