We performed long-term field observations and retrospective analysis of Berberis L. species for the territory of Nakhchivan Autonomous Republic. We registered six species (B. densiflora Boiss. & Buhse., B. iberica Stev. & Fisch. ex DC., B. integerrima Bunge., B. orientalisC.K. Schneid., B. sphaerocarpa Kar. & Kir., and B. vulgarisL.) and two forms (Berberis vulgarisf. alba West. and Berberis vulgarisf. lutea Regel) for this territory. The status of B. integerrima Bunge. and B. orientalis C.K. Schneid was determined, whereas Berberis vulgarisf. alba West and Berberis vulgarisf. lutea Regel forms were determined for Nakhchivan and Azerbaijan's flora for the first time. Berberis thunbergiif. atropurpurea form was introduced and used in parks and gardens. Shrubs surrounded by wild barberry can be come across in almost all areas of the Nakhchivan Autonomous Republic. They are the main subdominant plants in the formation of forest shrubs, spreading singly or in small groups in the upper, middle and sometimes in lower mountain ranges.
Key words: Nakhchivan Autonomous Republic, Berberis L., systematics, synonym, wild and cultivated species, spreading, introduction
Introduction
The Nakhchivan Autonomous Republic is a landlocked exclave of the Republic of Azerbaijan. Nakhchivan Autonomous Republic lays in the south-west of the Lesser Caucasus. It has borders with Iran (163 km, some of which lies along the Araz River), Turkey (11 km) and Armenia (224 km). Nakhchivan covers 5502.75 km2 and its territory stretches 158 km (from northeast to southwest) (Figure 1).
The natural borders are the northern Daralagez range, the eastern Zangezur range and the southern and south-western part of the Araz river. The lowest territory of the Republic, the Arazboyu plain (approximately 700 m above sea level), covers about one-third of the Republic, whereas the remaining two-thirds are located at altitudes between 1000 and 2000 m a. s. l. or higher. The highest point in Nakhchivan Autonomous Republic is Gapijig Mountain (3906 m). The Nakhchivan Autonomous Republic has particularly continental climate, with more than 2800 h of sunshine annually recorded in the Araz steppes. Rainfall in Nakhchivan varies between 200 and 600 mm, with low humidity throughout.
Minimum and maximum recorded temperatures in the region are - 30 °C and + 40 °C respectively. The area is characterized by hot dry winds, which blow for 50-70 days in the year (above 1000 m) (Babaev, 1999; Country Study, 2004).
Figure 1. Study area.
The territory of Nakhchivan Autonomous Republic has a rich flora and variety of vegetation. In the first place, it is due to the natural conditions of the area and due to the extremely complex geological and geomorphologic structure. In the formation of vegetation, anthropogenic factors have a greater role than physical factors. Due to the dry and continental climate, the Autonomous Republic differs from other regions of Azerbaijan. The territory covers the border of several botanical and geographical regions, namely, Caucasian, Central Asian and Iranian flora. About of 3021 species of higher plants were registered in this territory, which are concentrated in 908 genus and 176 families (Talibov and Ibrahimov, 2008). Some of these plants spread over the large areas and formed macrozones, while others are spread over small areas and form microcoenoses. The flora of Nakhchivan Autonomous Republic is constantly has been studied. However, the species belonging to Berberis L. genus have not been adequately investigated. In addition, the available results sometimes outdated and new species appear or penetrate to this area from the neighboring countries. That is why we should constantly monitor the spreading of Berberis L. species. Thought the wild barberry species were monitored and inventoried, their systematical composition, natural resource and potential usage are not investigated enough.
Our aim was to perform the floristic analysis of Berberis L. species and determine their spread in the Nakhchivan Autonomous Republic.
Materials and methods
Our research had been conducted with growing and collected herbarium of barberry species during 2017-2018 in forest shrubbery places of all mountainous zones of Nakhchivan Autonomous Republic. Regular expeditions have been made in the regions of Nakhchivan AR and the species of the genus of Berberis L. have been investigated in detail.
In the usage and determination of the gathered herbarium materials, classical and modern botanical-floristic methods, personal experiences, long-termed skills and experiences were referred here. To clarify the current situation of the representatives of Berberis L. in the flora of the Azerbaijan Republic, we checked the herbarium kept at Herbarium Fund of the Botany Institute of Azerbaijan National Academy of Sciences, Bioresources institute of the Nakhchivan Branch of Azerbaijan National Academy of Sciences and Nakhchivan State University. We also performed a comparative analysis of herbarium samples from various institutions and organizations web sites.
The classical and modern botanical floristic methods, fundamental complete works "Flora of the USSR" (Fedtschenko, 1937), "Trees and shrubs of Azerbaijan" (Zengiyev, 1964), "Higher plants of Azerbaijan" (Askerov, 2005, 2016), "Flora of Azerbaijan" (Rzazade, 1953), "Trees and shrubs of the USSR" (Lozina-Lozinskaya, 1954), Areas of trees and shrubs of the USSR" (Svyazeva and Sokolov, 1980), "Flora of the Caucasus" (Grossheim, 1950), "Dendroflora of the Caucasus" (Sahokiya, 1965), Talibov and Ibragimov (2008), Ibrahimov (2012, 2016), monographs Schneider (1905), Rehder (1949), Ahrendt (1961) have also been used. Defining of the names of systematical taxa with the authors have been performed according to the works of Cherepanova (1995) and "Taxonomical spectrum of the flora of Nakhchivan AR" (Talibov and Ibrahimov, 2008). The International Plant Names Index (IPNI) (www. ipni.org) and The Plant List (www.theplantlist.org) were consulted for nomenclatural information. For each locality, the coordinates and altitudes were determined by using GPS. The herbarium of all species were included in the Herbarium Fund of the Bioresources Institute of the Nakhchivan Branch of Azerbaijan National Academy of Sciences.
Results and discussion
The article provides information about spreading places of the species noted in before was defined and some newly spread zones of the species are informed. Prilipko (1939) reported that there were two species of BerberisL., namely, B. orientalises. Schneider and B. integerrima Bunge, whereas in 1954 he reported three species - B. vulgaris L., B. densiflora Boiss. & Buhse and B. iberica Stev. & Fisch. ex DC. and Grossheim (1950) reported three species B. vulgaris L., B. iberica Stev. & Fisch. ex DC.,
209 Taxonomic diversity of genus Berberis L.
B. densiflora Boiss. & Buhse. Rzazade (1953) registered two species B. iberica Stev. & Fisch. ex DC. and B. densiflora Boiss. & Buhse, which were supported by Zengiyev (1964) and were considered to be spread in Nakhchivan.
The information comes across about wild barberry in the area of Autonomous Republic in work of Asadov et al. (2001, 2014). The author noted three species - B. densiflora Boiss. & Buhse, B. iberica Stev. & Fisch. ex DC., B. vulgaris L. (Asadov and Asadov, 2001) and later he mentioned (Asadov et al., 2014) B. densiflora Boiss. Gurbanov (1996) noted B. vulgaris L., B. iberica Stev. & Fisch. ex DC.) spread in Nakhchivan basin. Askerov (2005) showed that B. vulgaris L. and B. iberica Stev. & Fisch. ex DC. spread in Azerbaijan flora, while B. densiflora Boiss. & Buhse adopted as free species in B. iberica Stev. & Fisch. ex DC. ibragimov (2005) gave information about spreading of B. vulgarisL., B. sphaerocarpa Kar. & Kir., B. densfflora Boiss. & Buhse, and B. iberica Stev. & Fisch. ex DC. for this territory.
A recent study of barberry species was done by Talibov and ibrahimov (2012, 2013). They noted that six wild barberry species were spread in this territory - B. densiflora Boiss. & Buhse., B. iberica Stev. & Fisch. ex DC., B. integerrima Bunge., B. orientalis
C.K.Schneid., B. sphaerocarpa Kar. & Kir. and B. vulgarisL.
Prilipko, nevertheless, reported B. integerrima Bunge, later he defined B. orientalisC.K Schneider as its synonym. Additionally, there are three variations - var. orientalis Boiss, var. littoralis Boiss, and var. brachhybotrys Boiss. But, the barberry species in Caucasus and Azerbaijan flora differed by leaves form and structure. Cherepanov (1995) presented and admitted in his last division B. integerrima Bunge and B. orientalisSchneid) as free species.
Our results and species composition of BerberisL. in the territory of autonomic republic were presented below. Genus. BerberisL. Spec. Plant. 330 (1753).
The barberry has spread in many regions of Azerbaijan, including Nakhchivan Autonomous Republic, from the lower to the upper mountain ranges. This plant is come across in many woods, wood glades, river valleys and bushes. The following species and forms of Berberis L. genus were spread in Nakhchivan Autonomous Republic.

B. orientalis plays an important role in the vegetation cover of the Nakhchivan Autonomous Republic. Prilipko (1939) also indicated eastern barberries in Nakhchivan. Further, it was reported as a synonym of B. vulgarisL. (Lozina-Lozinskaya, 1954; Grossheim, 1950; Rzazade, 1953; Fedtschenko, 1937). Cherepanov (1995) accepted that eastern barberry is also free species. We, thus, defined that in Nakhchivan Autonomous Republic B. orientalis C.K. Schneid. had tiny and small thorns, its leaves are ellipsoid and its corners are unclear cusps (Table 4).

Type: Described from Europe. Type in London. "Habitat in Europae sylvis", Herb. Cliff. BM. Common distribution: Caucasus, Europa, Anatolia borealis, Talysh, Persia boreo-occidentalis.
Distribution: We can come across simple barberries mostly in sparse forests, shrubbery, valleys of river and edge of the planting fields in the height of 1100-2300 m altitude. It grows as individually or in groups in the spreading areas. Sometimes it creates dense jungles. Around the Gilanchay village of the Ordubad region, a diverse species of peanut has formed along the valley of the same name. It is heat-resistant, cold and frost (Figure 9).
B. vulgaris L. is included in the book "Medicinal Plants of the Nakhchivan Autonomous Republic" and Talibov et al. (2018) indicated the ways of its use. It is polymorph for its morphology features. It has been determined that two species of B. vulgaris L. were spread in the autonomous republic flora according to the materials and literature data collected during expeditions to study the wild species of the barberry.

It is a 2 m many branched, thorny bushes. It differs from B. vulgaris by white berry. Its berry is oval and ovoid-oval, 0.7-0.8 cm and 1 -2 seeded. It has sweet sour. It is whitish and light brown when dry. Its seeds are brown, longish, pressed in the middle, blunt or sharp. It blossoms in May-June and grows in September-October. We have included this form to Azerbaijan and Nakhchivan Autonomous Republic flora (Figure 10).

Type: Described from Europe: "in Europa". Type in London.
Common distribution: South Caucasus, East of Turkey, Central and Northern Iran.
Distribution: It is spread with the other different species on the left of the road to Soyugdagh of Kotam, 38°53'33" N, 46°03'24" E village in Ordubad region of Nakhchivan Autonomous Republic and in the bushes between the same named village of Gilanchay and Bilav, 39°04'01" N, 45°49'30" E (Figure 12).

It is 1.5 m plant covered with firm thorns. It differs from B. vulgarisby bright yellowish berries. Its 1 -cm berries are longish-ovoid and 1 -2 seeded. Its taste is partially sweet. Dried fruits are yellow. Its seeds are light brown, longish-ovoid, pressed in the middle and sharp. It blossoms in May-June and grows in September-October. We also included this form into Azerbaijan and Nakhchivan Autonomous Republic flora (Figure 11).

Type: Described from Europe: "in Europa". Type in London.
Common distribution: South Caucasus, East of the Turkey, Central and Northern Iran.
Distribution: It is spread with the simple barberries on the left of the road to Soyugdagh of Kotam, 38°54'15" N, 46°03'43" E village of Ordubad region (Figure 12).

It is a 50-60 cm tiny and small thorny bush. The leaves can change their color from dark red to brown red (strong violet). The leaves are bright red in autumn. The inner view of flowers of 2-6 numbers with the flower group is yellow and its outside is reddish. Its 1 -cm berries are light or bright red. It blossoms in May-June, grows in September-October. Mature fruits of this plant are eatable and they remain on the branches even in winter (Figure 13).

Distribution: As a decorative plant, it is widely used in the greenery of parks and alleys of the city of Nakhchivan. Mammadov (2010) noted that Berberis thunbergii DC. is used for planting trees and grass in Baku and Absheron. It is possible to come across fresh bushes surrounded by wild barberries in Khanbulagh of Sharur, Arafsa of Julfa, Gilanchay of Lakatagh and Ordubad in Nakhchivan Autonomous Republic. They spread in the middle and rarely bottom of mountainous zones as single or in a group but not huge and it is one of the main subdominant plants for formation of forests bushes.
We defined six species and two forms of BerberisL. in Nakhchivan Autonomous Republic. These species are B. densifloraBoiss. & Buhse, B. iberica Stev. & Fisch. ex DC., B. integerrima Bunge., B. orientalis C.K.Schneid., B. sphaerocarpe Kar&Kir, and B. vulgarisL. The forms are Berberis vulgaris f. alba West. and Berberis vulgaris f. lutea Regel. Moreover, Berberis thunbergii f. atropurpurea form is used in the park planting and garden design being introduced in the cultivated conditions. The exact determination of species composition and geographical distribution of Berberis L. is difficult in Caucasus. In some cases, it is even impossible to define the precise boundaries of species range. The presence of significant intermediate forms among the barberry species testify the intensive hybridization. Many hybrid species are already found in South Caucasus,
particularly in the Nakhchivan Autonomous Republic. Hybrids of such common species as B. vulgaris and B. integerrima are
widely distributed. In addition, K. Browicz & J. Zielinski (1975) and R. Azadi (2009) registered similar hybrids in Iran and Northeast
Anadolu area.
