Graminoid

This article is about plants with a grass-like appearance. For the clade containing Poaceae and some related families, see Graminid clade.
Germinating fescue grass with long, blade-like leaves

In botany and ecology, a graminoid refers to a herbaceous plant with a grass-like morphology,[1] i.e., elongated culms with long, blade-like leaves. They are contrasted with forbs, herbaceous plants without grass-like features.

The plants most often referred to include the families Poaceae (grasses in the strict sense), Cyperaceae (sedges), and Juncaceae (rushes). These are not closely related but belong to different clades in the order Poales. The grasses (Poaceae) are by far the largest family, with some 12,000 species.
