Introduction
The Nakhchivan Autonomous Republic is one of the richest regions
of Azerbaijan for plant diversity. Among the wild fruits, species of rowans
(Sorbus L.) have been selected according to systematic composition.
During the course of research (Grossheim, 1952; Prilipko, 1954; Gasumova et al., 2014) some 11 species of the Sorbus L. type were identified,
namely – S. aucuparia L., S. boissieri Schneid., S. baldascii Deg. et
Fritsch. ex Schneid., S. graeca (Spach) Lood. ex Schauer, S. luristanica
(Bornm.) Schönbeck-Temesy, S. persica Hedl., S. roopiana Bordz.,
S. subfusca (Ledeb.) Boiss., S. takhtajanii Gabr., S. turcica Zinserl.,
S. umbellata (Desf.) Fritsch in this area. However, as a result of analysis of
the pomological features of the herbaria collected during the expeditions
conducted during 2004–2017 in the various areas of Nakhchivan Autonomous Republic, literature review (Grossheim, 1952; Prilipko, 1954; Ibragimov, 2008; Talibov & Ibragimov, 2013), and comparison of examples
of the herbaria materials kept in the fund of the Institute of Botany of the
Academy of Sciences of Azerbaijan, Institute of Bioresources of Nakchivan Branch of the Academy of Sciences of Azerbaijan and herbaria fund
of the Nakhchivan State University we identified some new species for
the flora of the Nakhchivan Autonomous Republic of the Azerbaijan
Republic; S. albovii Zinserl., S. armeniaca Hedl., S. buschiana Zinserl.,
S. caucasica Zinserl., S. fedorovii Zaikonn., S. kusnetzovii Zinserl.,
S. migarica Zinserl. and S. tamamschjanae Gabr.
Materials and methods
In order to clarify the current situation of the representatives of
Sorbus L. in the flora of the Azerbaijan Republic, we checked the
herbariums kept at Herbarium Fund of the Botany Institute of
Azerbaijan National Academy of Sciences, Bioresources İnstitute of the
Nakhchivan Branch of Azerbaijan National Academy of Sciences,
Nakhchivan State University. We also performed comparative analysis
of herbarium samples from various institutions and organizations web
sites. We also determined the status of Sorbus L. genus during the field
expeditions of 2004–2017 (Ibragimov, 2008; Askerov, 2011, 2016;
Talibov & Ibrahimov, 2013). We used the data from (Zinzerling, 1939;

It is either a tree or a shrub (Fig. 1a). Buds are naked or a little hairy.
Leaves are obovate or ellipsis shape. A little shrunken in trunk or round
shaped. Top side is sharp or obtuse, usually sharp tipped with 7–10 cm
length and 4–7 cm width. Side veins number is 8–11 pairs, top side is
naked (initially a little hairy along the veins), bottom side is green and
little hairy. Sides are serrated, top side is hardly visible double serrated,
sharp serrates reach the blade of the leaf. Sepal feels hairy, serrates are
of triangular shaped and sharp. Petals are egg-shaped. Fruits are round
or oval shaped of red color turning green afterwards. Blooms in May–
June and gives fruits in August–September.
Typus. Caucasus occidentalis, Reservatum Publicum Caucasicum,
in declivibus septentrionalibus montis Abago in betuletis ad rivum,
3.VIII.1929, A. İ. Leskov et A. P. Rusaleev (LE).
Habitat. Distributed in the middle and high mountain ranges,
spread among sparse forests and bushes at a height of 1,800–2,000 m
(2200 m) above sea level.
Distribution. distributed in the sparse forest surrounding Nurgut
village of the Ordubad district of the Nakhchivan Autonomous Republic, along with the oak, hawthorn, or pear types, or separately 18.VII.

in 1929 as a result of herbaria samples collected. While Y. D. Zinzerling
(1939) was systemizing the species related to Sorbus L. type he accepted S. albovii Zinserl. species as a separate species, however, E. C. Gabrielyan (1978) identified it as a synonym of S. subfusca (Ledeb.) Boiss.

type is tetraploid (2n = 68), while S. subfusca (Ledeb.) Boiss. is diploid
(2n = 34). These species also differ according to the variety of morphological symptoms (form, size, edge of the leaf, etc.). For this reason, it is
more expedient to treat S. albovii Zinserl. as a separate species as described by S. K. Czerepanov (1995). As noted by T. I. Zaikonnikova (1975),
the species S. albovii Zinserl. is found only in Dagestan and the Nakhchivan Autonomous Republic.
S. albovii Zinserl. to S. subfusca (Ledeb.) Boiss., a species described on
basis of samples collected in the North-West Caucasus (Abago Mountain), in her other article (Zaikonnikova, 1975) she accepted it as a separate species. According to I. T. Zaikonnikova (1980) the separation of
S. albovii Zinserl. and S. subfusca (Ledeb.) Boiss. species is confirmed
by the difference in their geographical distribution and the number of
chromosomes. Although the species S. albovii Zinserl. is found almost all
over the Caucasus, the territory of the species S. subfusca (Ledeb.) Boiss.

The species is derived from S. persica species in the form of the
leaves, the depth of the slices (in the S. persica, this depth is 1/4 to 1/5 of
the leaf), and S. caucasica type, the shape and smallness of the leaves,
the form of the leaf base part and the top (the S. caucasica sections are
two-thirds of a half width of the leaf moon) and uncut leaf boxes.

Zaikonnikova (1980) while S. buschiana Zinserl. is similar to S. albovii
Zinserl due to the shape of its leaves and morphological features, it is
still different in its thick skin type leaves greyish at the bottom, sepal

Habitatl. It is spread in the middle and high mountain ranges, at the
altitudes of 1,700–2,300 m above sea level in the oak woods, on the
slopes of sparse forests, in open rocky slopes, and among shrubs. It is
found alone or in groups in sparse oak woods or among shrubs along
with Rhamnus cathartica L., Viburnum lantana L., Lonicera iberica
Bieb., Sorbus graeca (Spach). ex Schauer, S. aucuparia L., Euonymus
verrucosus Scop., Berberis iberica Stev. & Fisch. ex DC., Juniperus

Ordubad region, in combination with oak, hawthorn, apple, pear, hips,
and so on or alone 04.IX.2015. T. H. Talibov, A. M. Ibrahimov.
This species is close to the species S. graeca, however differs in its
clearly visible serrated leaf margins, characteristic hairy and red colored
petals and fruits.
Despite A. M. Askerov stating in his book on Conspect of
Azerbaijan Flora (Askerov, 2011) that S. kusnetzovii Zinserl. is spread
in Azerbaijan, he subsequently denied this idea in his later book (Askerov, 2016). According to T. A. Gasimova, Z. S. Aliyeva and T. D. Safguliyeva (2014), the species S. kusnetzovii Zinserl.is spread in the
middle and high mountain ranges of the Greater Caucasus at the
altitudes of 1,200–2,400 m above sea level among oak woods, in sparse
forests, on open rocky slopes, and in shrubs.
Considering that S. kuznetsovii Zinserl. is a rare and endangered
species, T. S. Mammadov, E. O. Iskandar and T. H. Talibov included it
in the book on rare trees and shrubs of Azerbaijan (2016) and described
methods of its conservation.

It is a shrub of 0.5–2.0 m height (Fig. 4a). The buds are barely felt
haired. Leaves are more or less dermal and round shaped, (5) 7–9 (10) cm
long, (4.5) 6–7 (8) cm width, apex is blunt. The number of side veins is
8–10 pairs. Upper surface except the veins are naked or barely hairy.
Bottom surface veins are covered with thick white felt hair, surface of
veins is barely haired. Therefore, veins are clearly visible by their dark
color. The edges of the leaf are full margined from bottom, the tip is
(1/8–1/3) serrated. The serrates are small and sharp and their number is
20–25 from both sides. Leaf and flower stalk is short and white felt
haired. Sepal is white felt haired, triangular shaped bending down after
blossom and serrated. The mature fruit is dark red, with a length of 1.1–
1.3 cm and a width of 1.0–1.2 cm. Blossoms in May–June and fruits
grow in September–October.
Typus. Megrelia, mons. Migaria, 21.VII.1936, P. Panjutin (LE).
Habitat. In middle and high mountain ranges, in the oak forests at altitudes of 1,800–2,000 m above sea level, along the upper border of the forest, in rocky slopes, in sparse arid forests and shrubs in the limestone lands.
Distribution. It is spread in sparse forest surroundings of Nurgut
village in the Nakhchivan Autonomous Republic, either together with
juniper, barberries, oak, hawthorn, pear, apple, hips etc. or or individually 02.XI.2011. T. H. Talibov, A. M. Ibrahimov.
It is closer to the species S. graeca and differs by its smaller petiole
leaves. S. migarica Zinserl. the length of the petiole is (0.2) 0.5–0.7 (1.0) cm,
while S.graeca is 1.0–1.5 or 1.5–2.0 cm length. The serrates of the leaf
margin are collected from the center of the apex of the leaf, not from the
center of the leaf (or even not from the center to the base) as in S. graeca.

In the information of I. T. Zaikonnikova, S. migarica Zinserl species is registered as S. graeca var. cuneata Zinserl. on basis of subsequent
analysis of herbarium samples collected from the Caucasus.
This kind of definition is also met in the samples stored in the Herbarium of the Institute of Botany of the Academy of Science of Azerbaijan (In the samples of the Herbarium Fund of the Institute of Botany of the
Academy of Science of Azerbaijan, samples are shown as collected in
Mazra and Urmus villages (16.08.1933, Karyagin) and Urmus village
area (02.08.1933, İsayev; 15.08.1933, Karyagin) of the Ordubad region.
Therefore, E. S. Gabrielyan (1978) showed S. migarica Zinserl species as
a synonym of S. umbellata (Desf.) Fritsch var. orbiculata Gabr. (S. graeca
var. orbiculata Zinserl.) species. However, as a result of analysis of the
literature sources and of the collected herbarium smaples it was concluded
that it is reasonable to accept S. migarica Zinserl. as a separate species due
to the variety of its morphological characteristics and geographical area as
was mentionned by S. K. Czerepanov (1995).
I. T. Zaikonnikova (1973) also mentioned that S. migarica Zinserl.
species is not a narrowly endemic species as described by Y. D. Zinzerling (1939) but spread around the entire Caucasus.

felt haired. Its margin is slightly serrated and has a significant deep short
lobe. The number of side veins is 7–9 pairs. Flower group is a multiflorous and peltate. The petiole initially is hairy and then becomes naked.
The sepal serrates are triangular in shape,short and sharp. The petals are
white and ovoid. The fruits are 1.2 cm in length, 1.1 cm in width and are
wide-elliptic, 5–11 (18) are collected together in scutellum. The mature
fruit is bright orange and bright. Light brown seeds are 0.6 cm in length,
0.2 cm in width. The taste is not sweet, and the mouth twists. Blossoms

Conclusion
Thus, on basis of the analysis of herbarium materials collected during
the expeditions of 2004–2017 and by literature review, we registered that
19 species of Sorbus L. species are found in the wild flora of the Nakhchivan Autonomous Republic. The species S. aucuparia (VU A2c+3cd)
is included in the Red Book of Azerbaijan (Red Book of the Republic of
Azerbaijan, 2013). Herbarium samples of S. aucuparia L., S. boissieri
Schneid., S. baldascii Deg. et Fritsch. ex Schneid., S. roopiana Bordz.,
S. luristanica (Bornm.) Schönbeck-Temesy, S. subfusca (Ledeb.) Boiss.,
S. takhtajanii Gabr., S. persica Hedl., S. graeca (Spach) Lood. ex Schauer,
S. turcica Zinserl., S. umbellata (Desf.) Fritsch, S. albovii Zinserl., S. armeniaca Hedl., S. buschiana Zinserl., S. caucasica Zinserl., S. fedorovii
Zaikonn., S. kusnetzovii Zinserl., S. migarica Zinserl. and S. tamamschjanae Gabr. collected during the expeditions were delivered for storage in
the Herbarium Funds of the Institute of Botany of the Academy of
Science of Azerbaijan and Institute of Bioresources of the Nakhchivan
branch of the Academy of Science of Azerbaijan.
Despite rowan trees being widely distributed in the forests of the
territory of the Nakhchivan Autonomous Republic, we registered that
they are mostly present in high, middle, and sometimes lower mountain
ranges at the edges of forests, mostly individually or in small groups.
We suggested that rowan species are the subdominant tree plants in the
arid and sparse forests.
