Autumn Bent

The Autumn Bent (Agrostis perennans) is a species in the genus Agrostis. Typically found in grasslands, wetlands, forests, and cultivated landscapes. Agrostis perennans contributes to the biodiversity of its native ecosystems.

Clavate Bent

The Clavate Bent, Agrostis truncatula, is a small tufted grass in the family Poaceae found in rocky, open habitats across the western Mediterranean region, including Spain, Portugal, and northwestern Africa. The common name refers to the somewhat club-shaped or truncated appearance of its spikelets. Like other Agrostis species, Clavate Bent grows in dry, thin-soiled, often acidic substrates on cliff faces, rocky outcrops, and sandy soils at low to moderate elevations. It is a perennial species producing slender, erect culms with fine, narrow leaf blades and open to contracted panicles of small, one-flowered spikelets. The genus Agrostis is one of the most species-rich grass genera in temperate regions, with many species adapted to disturbed and marginal habitats where competition from larger grasses is reduced. Agrostis truncatula provides ground cover and forage in open habitats, contributing to soil stabilization on steep rocky slopes. The species is not currently considered threatened globally, though its preference for rocky, nutrient-poor habitats means that it may be sensitive to changes in land use and vegetation succession as shrub and forest cover expands in the absence of traditional grazing.
