Parallel venation is found in:

Parallel venation refers to the arrangement of veins in a leaf or leaflet where the veins run roughly parallel to each other along the length of the leaf, without forming a complex branching pattern. This type of venation is commonly found in monocot plants. Monocots are one of the two major groups of angiosperms (flowering plants), the other being dicots.

Examples of plants with parallel venation include:

Grasses: Grasses are prime examples of plants with parallel venation. The leaves of grasses have long, narrow blades with parallel veins running from the base to the tip of the leaf.

Lilies: Lilies are another example of monocots with parallel venation. Their leaves also exhibit parallel veins.

Banana Plants: Banana leaves have prominent parallel veins that extend from the midrib to the edges of the leaves.

Palms: Palms, including coconut palms and date palms, have leaves with parallel venation.

Corn (Maize): The leaves of corn plants display parallel venation, with long veins running parallel to each other.

Orchids: Many orchid species exhibit parallel venation in their leaves.

These are just a few examples of plants that exhibit parallel venation. It's important to note that not all monocots have parallel venation, and there can be some variation within this group as well.
