Aponogeton ulvaceus

About

Aponogeton ulvaceus is a submerged aquatic plant in the Aponogetonaceae family. It has a small cone shaped, slightly hairy rhizome about 30 mm in diameter. The leaf blades have a base that tapers gradually, pale green in colour, over 50 cm (20 in) long and 8 cm (3 in) 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.
