Margin of ponds &c. often in rather dry places, South Carolina! to Florida!
and Louisiana !—Stem creeping, throwing up several leaves from each node.
Leaves 1-2 inches long, somewhat coriaceous, often truncate at the base :
petioles 3-6 inches long. Involucre of 2 concave bracts, nearly as long as
the almost sessile flowers. Stamens shorter than the petals : anthers brown.
Fruit with prominent ribs, somewhat reticulated.—According to Chamisso,
this species is not distinct from H. Asiatica ; but our specimens of the latter
have thinner and broader leaves, very short peduncles, and more reticulated
orbicular and emarginate fruit.
6* H. ranunculoides (Linn. f.): glabrous; leaves orbiculUr-reniform,
3-5-lobed, the lobes crenate ; peduncles much shorter than the petioles;
umbels 5-10-flowered ; pedicels very short; fruit orbicular, smooth, very
obscurely 2-ribbed on each side.—Linn. f . ! suppl. p. i77 ; Rich, Hydr. f.

In water, Pennsylvania (Muhlenberg) and Virginia (Mr. Ruffner!) to
Georgia! and Louisiana! July-Aug.—Stems creeping or floating. Leaves
1-2 inches in diameter, usually deeply 3-lobed; the middle lobe narrower
and a little longer than the others : petioles 4-42 inches long. Peduncles
1-3 inches long : pedicels 1-2 lines in length. Fruit about a line and a half
m diameter.

Calyx-tube subglobose; the margin obsolete. Petals roundish, entire,
obtuse. Fruit subglobose; the commissure excavated, nearly orbicular, with
2 vittae. Carpels unequal, with 5 filiform ribs ; 3 of them dorsal and narrow,
•the others marginal and united with the thick corky margin which surrounds
the fruit: intervals with single vitt*. Carpophore adnate, indistinct. Transverse
section of the seed orbicular.—Very small glabrous creeping herbs,
(natives of the United States and Buenos Ayres), with linear entire succulent
leaves (or rather petioles without a lamina), marked with transverse lines.
Umbels few-floWered, simple, involucrate. Flowers white or rose-color,
perfect, pedicellate. .

Muddy banks of rivers, near saltwater, Massachusetts, Rhode Island!
and Connecticut! to Louisiana! May—July.—Stemscreeping and rooting
in mud. Leaves erect, 1-2 inches long, about a line and a half wide at
the summit, marked with 4-6 transverse lines. Umbels 8-12-flowered,
Involucre 5-6-leaved. Fruit a line in diameter : commissure with a broad
white corky margin. Vittae red, conspicuous.—This genus does not accord
with the present tribe except in habit; yet we are unwilling to establish
a peculiar tribe for its reception.

Calyx-tube compressed, somewhat 4-angled ; the limb 5-toothed. Petals
elliptical, entire, acute. Styles filiform. Fruit didymous, much contracted
at the commissure, turgid, somewhat pyramidal and 4-angled. Carpels
without vittae ; the back flattened, with an oval outline : ribs obsolete. Seeds
plane internally, slightly convex externally,—Slender herbs (mostly South
American), scabrous with a stellate or simple pubescence. Leaves opposite!
simple, lobed or toothed. Stipules lacerate, scarious. Umbels axillary,
simple, few-flowered : flowers minute,

Dark moist places about streams, California, Pouglas ! Nuttall! April.
— © Stem 6-15 inches long, nearly simple; the nodes producing short
branches. Leaves about three-fourths of ah inch in diameter ; the sinuses
acute : lower petioles 1-2 inches long. Fruit densely hirsute with stellate
hairs. Carpels rather smaller than a mustard seed, at first inflated, the
calyx not adhering at the back, an empty space being left between it and
the pericarp; the seed also occupies but a part of the carpel (the inner
portion), so that a transverse section exhibits two cells, one formed by the
non-adherence of the calyx at the back, the other the Cavity of the inflated
pericarp which is only partially occupied by the seed. At maturity the seed
fills the cavity of the carpel, and the exterior cavity Collapses, but the dorsal
part of the calyx never adheres to the fruit.—We strongly suspect that B.
tenera, Spreng., to which Hooker & Arnott (in Bot, wise. 3. p. 346) refer B.
geraniifolia, Cham. Sf Sehlecht. and B. nodiflora, Presl, is not distinct from
this plant.

Transverse section of the fruit somewhat orbicular. Carpels
with 5 equal primary and no secondary ribs, or covered with scales
or prickles, when the ribs are obliterated. Vittae none, or numerous
when the fruit is prickly. Seed flattish on the face.—Umbels
fascicled or capitate, simple, or somewhat irregularly compound.
