Peltate-leaved Water-Croivfoot.
PO L YA ND R IA Polygynia.
Gen. Char. Calyx of 5, rarely 3 leaves. Petals 5
or more, with a nectariferous pore at the base.
Pericarps without awns.
Spec. Char. Stem floating. Submersed leaves
loosely trifurcate, divided into capillary rather
rigid divaricate segments, which spread in all
directions, and do not collapse; floating leaves
long-stalked, subpeltate, half- 3-5-fid ; segments
obovate, with 2—3 notches. Petals roundish,
becoming obovate-cuneate, 9-veined, contiguous,

O T EM floating, often rising out of the water, bluntly angular.
Submersed leaves light green, two or three times trifurcate,
in a loose manner, afterwards bifurcate; intermediate
divisions smaller than the others, all divaricate at each fork;
segments filiform, rather rigid, not collapsing when taken out
of the water. Petioles very short or wanting. Floating leaves
rather convex (but in this plant and its allies the young leaves
are flat or even slightly concave), divided (often scarcely halfway
down) into three lobes, of which the central is smaller
and shorter; outer edge of the leaf more or less (usually much)
rounded at the base; outline of leaf forming about frds of a
