Grass leaves are nearly always alternate and distichous (in one plane), and have parallel veins.

All are monocotyledons, typically with narrow leaves and parallel veins.

Like many plants in this genus, the leaves have parallel veins.

The leaves have parallel veins, and where the blade meets the culm, there is a structure called the ligule.

They have three or five parallel veins that diverge in the wider part of the leaf.

The leaf margins are entire and have parallel veins.

Many monocots also have leaves with parallel veins.

Three parallel veins of Ordovician slate run through mid Wales.

In the males median and ulnar wing cells are quite large, with parallel veins.

Five parallel veins on the leaf, venation more evident under the leaf.
