How tall is a Potamogeton?
What does a Potamogeton stipule look like?
What is Potamogeton amplifolius?
Leaf shape has been found to be highly plastic, with variability due to changes in light, water chemistry, planting depth, sediment conditions, temperature, photo period, waves, and seasonality. All Potamogeton have a delicate membranous sheathing scale, the stipule , at the leaf axil.
Potamogeton amplifolius × Potamogeton praelongus → This rare pondweed hybrid known from ME, VT. It has leaf blades that are weakly arched, sessile to somewhat clasping, and with mostly 15–21 veins.
Floating leaves may be similar in shape to that of the submersed, or they may differ considerably. Submersed leaves have no cuticle and do not have well-developed epidermis. All species of Potamogeton have submersed leaves; some also have floating leaves.
All species of Potamogeton produce submersed leaves, which are very thin, translucent, and generally occur below the surface of the water (unless stranded). Floating leaves are thick, opaque, and occur on the surface of the water during normal seasons.
Leafy pondweed is the only species of pondweed (Potamogeton) with linear leaves that also has an undulating wing-like keel on the fruits.
Important features of the fruit include presence or absence of lateral and abaxial wings, ribs, ridges, or keels. Here, "ribbed" indicates a raised "vein" on a rounded surface; "ridged,"; a ridge with an obtuse angle; "keeled," a ridge with an acute angle; and "winged," a ridge that appears to have a wing distally.
