    Habit
    Apparently glabrous aquatic with all submerged parts covered with a profuse clear slimy jelly-like mucilage; the outsides of the sepals and petals, the undersurfaces of the leaves, submerged petioles, pedicels, etc., are covered with minute purplish glandular hairs which may secrete this mucilage.
    Leaves
    Leaf-blades round or broadly elliptic, 2.5–11.5 cm. long, 1.5–7 cm. wide, entire, green above, usually reddish-brown or purplish beneath with 12 nerves radiating from the centre; petiole-length depending on the depth of the water, 0.05–1 m. long or more, slender, ±1.5 mm. in diameter.
    Pedicel
    Pedicels reddish-brown, 4–5 cm. long, 2 mm. in diameter.
    Calyx
    Sepals purplish- or brownish- red, elliptic or narrowly oblong, 0.9–1.4 cm. long, 3–6 mm. wide, rounded atthe apex.
    Corolla
    Petals crimson, purplish- or brownish-red, narrowly oblong or linear-oblong, 1.2–1.7 cm. long, 3–4 mm. wide, narrowly rounded at the apex.
    Stamens
    Filaments of the stamens filiform, 1 cm. long, papillose; anthers reddish, linear-oblong, 3.5 mm. long, apiculate.
    Carpels
    Carpels fusiform or narrowly ovoid, 5 mm. long, 1.5–2 mm. wide, sparsely papillose; stigma simple, 3–4.5 mm. long, papillose all over save for a narrow longitudinal area facing the perianth.
    Fruits
    Fruiting carpels ellipsoid or fusiform, 0.6–1 cm. long, 2–2.5 mm. wide; stigma persistent.
    Seeds
    Seeds pale brown, ellipsoid, 2.7–3.5 mm. long, 2–2.3 mm. wide.
    Habitat
    akes, swampy pools, etc.; 1120–2750 m.
    Distribution
    K3 T1 T7 U4 also known from Tertiary and interglacial deposits in Europe

    Cabombaceae, H. Wild. Flora Zambesiaca 1:1. 1960

    Habit
    Glabrous aquatic plant with all its submerged parts covered with a profuse, clear, slimy mucilage.
    Leaves
    Leaves floating, rotund, peltate, 7.5 (10) x 5–7 cm., margin entire, green above, reddish-brown or purplish below, nerves 12, radiating from the apex of the petiole, rather faint, petiole reddish-brown, attached at the centre of the leaf-blade, up to 1 m. or more long according to the depth of the water, c. 1.5 mm. in diam.
    Flowers
    Flowers solitary, axillary on reddish-brown peduncles up to c. 8 cm. long, c. 2 mm. in diam.
    Calyx
    Sepals purplish-brownish-red, petaloid, c. 1.4 x 0.3 cm., narrowly oblong, apex rounded.
    Corolla
    Petals similar to the sepals but slightly larger.
    Stamens
    Stamens with slender papillose filaments up to 1 cm. long; anthers reddish, 3.5 mm. long, narrowly oblong, apiculate at the apex.
    Carpels
    Carpels 5 x 2 mm., narrowly lanceolate-ovoid, sparsely papillose, stigma simple, 3 mm. long, papillose.
    Fruits
    Ripe carpels 7 x 2 mm., ellipsoid with a persistent stigma.
