Embryo intra albumen, erectus, leviter curvatus, inversus:
Cotyledones parvee: Radicula supera. (
Root perennial (r)> creeping, jointed, of a brown colour,
filiform, fibrous a t the joints.
Stalks from one to two feet in length or more, according
to the depth of the water in which they are
immersed, rounded, smooth, tender, weak, branched,
jointed, throwing out fibres.
Leaves oppbsite, sessile,smooth; the bottom ones,under
water, an inch or two in length, linear, wide apart^
as they grow up gradually becoming broader; the
top ones growing more closely together form little
stars on the surface o f the water, and become o f
an oval or roundish shape, faintly ribbed, and
finely dotted with impressed dots, emarginate.
F lowers inconspicuous, growing from the axils of the
leaves, sessile, hid beneath the uppermost leaves,
male and female on the same plant, often opposite.
