Cape Pondweed is an aquatic plant growing from a tuberous rhizome. The often mottled leaves float on the water surface from a leaf-stalk up to 1 m long from the rhizome; the leaf blade is narrow oval, 6–25 cm long and 1.5–7.7 cm broad, with an entire margin and parallel veins. The flowers are produced on an erect spike with two branches at the tip like a 'Y', held above the water surface; they are sweetly scented, with one or two white tepals 1–2 cm long, and six or more dark purple-brown stamens. Cape Pondweed is native to Cape Province in South Africa, cultivated elsewhere.
