''Aponogeton abyssinicus'' is an amphibious plant found in East Africa, from Ethiopia to Malawi and Zaire. Root stock tuberous or oblong, up to 2.5 cm diameter. Submersed leaves initially strap-shaped, up to 12 cm long and 6 mm wide, continuing lanceolate to obovate, up to 8.5 cm long, 2.6 cm wide and up to 10 cm long petiolate. Blade thin and slightly transparent, with a narrowing or decurrent base and acute or obtuse apex. Adults floating, up to 50 cm long petiolate. Floating leaf blade linear to ovoid, rarely cordate, up to 16 cm long and 5 cm wide, usually considerably smaller. Emersed leaves shaped like the floating leaves, slightiy leathery and shorter petiolate.
Peduncle up to 45 cm long, angled, dark red to green coloration, slightly pubescent underwater, almost glabrous above water, not swollen under the inflorescence. Spathe 1.0-1.6 cm long, caducous. Inflorescence featuring two 1.5-5-cm long spikes with omni-lateral flowers; 2 tepals, violet or white coloration; 6 stamens (none in apomictic plants); 3 carpels (up to 7 in apomictic plants). Fruit up to 7 x 2.75 mm large, with (4-) 7-10 seeds, sized 1-2 x 0.75 mm, double testa.
==Culture==
''Aponogeton abyssinicus'' is a rarely imported plant, the maintenance of which is entirely possible in an aquarium. For cultivation, preferably soft water as well as nutrient-rich and loose substrate is recommended. The best water temperature is . In the aquarium, the white-flowering form of ''A. abyssinicus'' forms a 15 cm wide and 10 cm tall rosette consisting of light green leaves, so that it may be considered for the foreground. The floating leaves, which only rarely form in aquariums, should be removed so that the later leaves will again remain short petiolate. An emersed or semi-aquatic keeping is possible under conditions of high humidity. Best cultivation results are achieved in shallow water. Propagation can occur only sexually through the very tiny seeds. Though they mostly germinate well, the rearing of the young plant is, in fact, extremely difficult and requires a lot of effort.
