''Aponogeton ulvaceus'' is a submerged aquatic plant with a small cone shaped, slightly hairy rhizome about 1.18 inches (30mm) in diameter. The leaf blades have a base that tapers gradually, pale green in colour (reddish under intense light), 20+ inches (50+ cm) long and 3 inches (8 cm) broad, with a wavy margin on petioles of an equal length, and in appearance slightly translucent. A single bulb may produce up to forty leaves in good conditions. No floating leaves are formed. The yellow flowers are produced on one or two, and sometimes more, erect spikes. ==Origin== It is distributed throughout central and northern Madagascar. In the wild, the plant is permanently submerged and grows in both still and moving waters and sunny and partially shaded environments.
