Sago Pondweed

Sago pondweed grows from thickly matted rhizomes (underwater stems). It has no floating leaves. The stems are thin and have highly branched leaves, about 1/16 of an inch wide and 2 - 12 inches long that taper to a point. The leaves grow in thick layers and originate from a sheath. The fruit at the end of stems are small and nut-like.
