Cabombaceae, B. Verdcourt. Flora of Tropical East Africa. 1971

Morphology General 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.
Morphology 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.
Morphology Reproductive morphology Flowers Pedicel
Pedicels reddish-brown, 4–5 cm. long, 2 mm. in diameter.
Morphology Reproductive morphology Flowers Calyx
Sepals purplish- or brownish- red, elliptic or narrowly oblong, 0.9–1.4 cm. long, 3–6 mm. wide, rounded atthe apex.
Morphology Reproductive morphology Flowers 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.
Morphology Reproductive morphology Flowers Androecium Stamens
Filaments of the stamens filiform, 1 cm. long, papillose; anthers reddish, linear-oblong, 3.5 mm. long, apiculate.
Morphology Reproductive morphology Flowers Gynoecium 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.
Morphology Reproductive morphology Fruits
Fruiting carpels ellipsoid or fusiform, 0.6–1 cm. long, 2–2.5 mm. wide; stigma persistent.
Morphology Reproductive morphology 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
