Distribution and new variability of Aegilops cylindrica Host in Azerbaijan

This paper presents results of surveys carried out during 2009–2016 in different regions of Azerbaijan to study the distribution of Aegilops cylindrica . Two new varieties and four new formae have been identified within this species, based on spike morphology. Eco-geographical data result from both herbarium specimens and from monitoring in the wild. Ecological information results from climate data (altitude, rainfall, temperature) from within the areas of collection. We also present information on the description, systematics and bioecological features of Ae. cylindrica , as well as essential nomenclature, distribution, and habitats in Azerbaijan and beyond.
