parallel-veined leaf

Thân thiện

A long, slender parallel-veined leaf lies on a wooden table next to a sketchbook.

Definition

Noun: A leaf whose primary veins run parallel to each other from the base (or stem) to the tip of the leaf, rather than forming a branching, net-like pattern. This venation is typical of monocotyledonous plants.

Examples

• To distinguish between plant groups, observe whether the leaf is a parallel-veined leaf or a net-veined leaf.

Advanced Usage

• The characteristic is often discussed in the context of plant evolution and taxonomy: "The prevalence of parallel-veined leaves is a key morphological trait of the monocot clade."
