Abstract 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.

Aegilops cylindrica Host (jointed goatgrass) is an
annual wild grass (Eig 1929) distributed in the
Mediterranean, Middle Eastern and Asiatic regions
(Kihara et al. 1965; van Slageren 1994: Figs. 35–38).
Overall, the world distribution of Ae. cylindrica is
roughly stationary. However, while van Slageren
(1994: 206 and Fig. 37) classiﬁed most localities in
Italy as adventive, more recently Perrino et al. (2014:
339) considered distribution in various regions of Italy
(Friuli Venezia-Giulia, Liguria, Alto Adige, etc.) as
natural, varying among the regions from common to
rare, Lower Risk to Critically Endangered. Most
recently the species was conﬁrmed in Slovakia (Elia
et al. 2013), while the known distribution in Bulgaria
and Hungary shows no regression (Zaharieva et al.
et al. 2015). In addition, a 2009 study
on the genetics of Ae. cylindrica throughout its native
range and the USA based on germplasm samples
showed the distribution range in Asia (Ghandi et al.
2009: Figs. 1–2) strikingly similar to van Slageren’s
(1994: 204, Fig. 35) herbarium specimen-based
assessment of 25 years before. Still, the exact distri-
bution of the species is somewhat difﬁcult to ascertain
due to its capacity for adventive settlement (van
Slageren 1994: Figs. 36–37), but no essential change
has appeared in recent times.
Jointed goatgrass is a tetraploid species with the
genome coded as ‘‘DC’’, thus including the D-genome
