Aira
Definition
A taxonomic genus of annual herbaceous plants within the Poaceae (Gramineae) family, structurally characterized by slender, thin stems and delicate inflorescences in the form of branched panicles, being adapted to dry, sandy, or siliceous soils. Natively distributed throughout the temperate regions of Eurasia and North Africa, these small-sized grasses hold special ecological importance in fixing fragile soils and as indicators of substrate acidity, with some species used in decorative dried flower arrangements due to their fine and persistent appearance.
