Encyclopedia
Potamogeton epihydrus is a species of aquatic plant
known by the common name ribbonleaf pondweed. It is native to much of North America, where it grows in water bodies such as ponds, lakes, ditches, and slow-moving streams. This is a perennial herb producing a narrow, compressed stem branching to a maximum length which may exceed one meter. It has two types of leaf. Submersed leaves are up to 25 centimeters long but not more than one wide, linear in shape and ribbonlike. Leaves that grow to float on the surface are shorter and wider, up to 8 centimeters long and 3 wide. They are borne on long petioles

Petiole (botany)
In botany, the petiole is the stalk attaching the leaf blade to the stem. The petiole usually has the same internal structure as the stem. Outgrowths appearing on each side of the petiole are called stipules. Leaves lacking a petiole are called sessile, or clasping when they partly surround the...

Inflorescence
An inflorescence is a group or cluster of flowers arranged on a stem that is composed of a main branch or a complicated arrangement of branches. Strictly, it is the part of the shoot of seed plants where flowers are formed and which is accordingly modified...
