Cette plante est \u00e0 distinguer (et mal distingu\u00e9e ici) d’Agrostis gigantea \u00e0 grande panicule (au moins 20 cm) contre jusqu’un peu plus de 20 cm de haut pour A. capillaris (l’exemplaire photographi\u00e9 pr\u00e9sente une panicule assez forte). Agrostis gigantea se distingue par une ligule plus haute que large, et dent\u00e9e. Agrostis gigantea produisant des rhizomes forts, et Agrostis capillaris \u00e9tant un peu plus cespiteuse. La plante est prise un peu t\u00f4t dans la saison: le groupe gigantea\/stolonifera pr\u00e9sente des pal\u00e9oles \u00e0 apex obtus, et le groupe capillaris des pal\u00e9oles<\/a> \u00e0 apex bident\u00e9s.<\/p>\n\n\n\n

Agrostis capillaris est eurasiatique.<\/p>\n\n\n\n

La vari\u00e9t\u00e9 alpigena est un peu moins robuste, et est subalpine.<\/p>\n\n\n\n
