- Description
- Aponogeton elongatus subsp. elongatus is a tuberous, aquatic perennial plant with mainly submerged leaves and a few floating leaves. The submerged leaves are narrow to broadly elliptic in shape, green or dark green to maroon-green, up to 34cm long and 0.8-3.7cm wide. The floating leaves are narrowly elliptic to slightly inverse-egg-shaped and 9-19cm long by 2.2-3.5cm wide. The leaf stalks are up to 1m long, depending on the water depth. The floating leaves are not commonly formed in the subspecies.¬
The spike-like clusters of yellow flowers are well-spaced, inserted evenly around the spike which is a stalk reaching 90cm long. The fruits are rounded, thick-coated, 2.5-5.8mm long by 1.8-5.0mm wide with a lateral beak to 1.5mm long. There are 2-5 seeds per fruit, elliptic in shape with a single, thin seed coat.
