Les vulpies sont distinctes parce que les glumes<\/a> sup\u00e9rieures et inf\u00e9rieures sont tr\u00e8s in\u00e9gales. Les vulpies demandent un peu d’attention pour la d\u00e9termination. En ce qui concerne Vulpia bromoides, on doit regarder de pr\u00e8s notamment les \u00e9pillets.<\/p>\n\n\n\n

L’inflorescence est \u00e9loign\u00e9e de la derni\u00e8re gaine. La longueur de la glume inf\u00e9rieure atteint un peu moins de la moiti\u00e9 de la glume sup\u00e9rieure.<\/p>\n\n\n\n

Vulpia bromoides a des ar\u00eates longues mais moins que chez V. myuros et que chez V. muralis. Le rapport ar\u00eate\/ lemme < 1,5; la longueur de la glume est presque \u00e9gale, l\u00e9g\u00e8rement inf\u00e9rieure \u00e0 celle de l’ar\u00eate. <\/p>\n\n\n\n

Les lemmes sont plus larges que ceux de V. muralis ;i.e les \u00e9pillets apparaissent un peu plus dodus que chez les autres vulpies.<\/p>\n\n\n\n

Noter que la longueur de l’inflorescence de Vulpia bromoides est en moyenne plus courte que celles de Vulpia muralis et donc plus courte encore que celle de Vulpia myuros.<\/p>\n\n\n\n

Le genre Vulpia s’hybride avec le genre Festuca (Festuca rubra). Il y a donc un probl\u00e8me sur le nom. Les Festuca \u00e9tant tr\u00e8s nombreuses, r\u00e9gler la question risque de demander du temps.<\/p>\n\n\n\n
