Distribution of
Orobanche zajaciorum
in Armenia.
Distribution:
—Mainly southeastern (
Syunik prov.
, eastern slopes of the Zangezur mountain range), rarely in central parts (
Gegharkunik prov.
, eastern slope of Pambaki mountain range) (
Fig. 44
).
General distribution:
—Probably endemic to the Caucasus, occuring in
Georgia
(
Piwowarczyk 2015a
),
Armenia
(Piwowarczyk in Nobis
et al
. 2016), and recently in
Russia
, NW Greater Caucasus: Republic of
Adygea
(
Rätzel & Uhlich 2016
).
Habitat:
—Rocky slopes, often sandy and loamy, rocky steppe communities, usually
1400–2000 m
.
Hosts:
—
Scutellaria
sp.
(
Lamiaceae
), such as
S. karjaginii
Grossh.
,
S. sosnowskyi
Takht.
,
S. orientalis
L.
Phenology:
—Flowering (May) June (July), fruiting (June) July (August).
Conservation status:
—Endangered (EN) – B 2ab(iii). AOO is less than
500 km
2
, severely fragmented, existing at no more than 5 locations (3 locations in 2 floristic regions). Populations are usually small, containing from a few to a dozen individuals. Limiting factors are restricted EOO and AOO, loss/degradation of habitats caused by overgrazing and expansion of mining areas.
Notes:
—Due to its small size, small distinctively curved geniculate flowers (to
17 mm
), simple and narrow calyx segments, as well as its peculiar host, it is difficult to confuse with other taxa of the
Orobanche
subsect.
Orobanche
[
O
. trib./Grex
Galeatae
sensu Beck] or others.
