Plants aquatic; leaves less than 4' tall, the petioles stout, not conspicuously septate, the blades linear or spatulate dilations at the top of the petioles, or wanting; scape shorter than the leaves, stout but weak, the inflorescence with but one whorl; sepals ovate to orbicular-ovate, becoming ii" long; fruiting pedicels stout, about 5" long or less; fruit-heads 2V-3" in diameter; achens cuneate, i"-i" long, the beak much below the top of the achene-body, the nar- row dorsal wing thin.

PI. 993. 1753- Perennial aquatic or bog herbs, mostly with tuber-bearing or nodose rootstocks, fibrous roots, basal long petioled nerved leaves, the nerves connected by numerous veinlets, and erect, decumbent or floating scapes, or the leaves reduced to bladeless phyllodia (figs. 241, 242). Flowers monoecious or dioecious, borne near the summits of the scapes in verticils of 3's, pedicelled, the staminate usually uppermost. Verticils 3-bracted. Calyx of 3 persistent sepals, those of the pistillate flowers reflexed or spreading in our species. Petals 3, white, deciduous. Stamens usually numerous, inserted on the convex receptacle; anthers 2-celled, dehiscent by lateral slits; staminate flowers sometimes with imperfect ovaries. Pistillate flowers with numerous distinct ovaries, sometimes with imperfect stamens; ovule solitary; stigmas small, persistent. Achenes numerous, densely aggregated in globose or subglobose heads, com- pressed. Seed erect, curved; embryo ho
