How to Manage Pests

Identification: Characteristics of Broadleaves

Leaf veins

Depending on the type of plant, leaf veins are either parallel or netted in pattern.

In leaves with netted veins, major veins branch from the main ribs and subdivide into finer veinlets. Fruit and deciduous trees, vegetable plants (not corn), most wildflowers, and many shrubs and flowers are examples of plants with netted veins.

In leaves with parallel veins, major veins most commonly run parallel to each other the length of the leaf. Less typically parallel veins run laterally from the midrib of the leaf to the leaf edge (not shown). Examples of plants with parallel veins are sedges, cattails, lilies, irises, and grasses (e.g., corn, rice, wheat, turf grasses).
