Karabakh and Zangezur are the south-eastern end of the Lesser Caucasus, and they are distinguished by their climate and landscape diversity with a rich in vegetation. Analysis of literature and herbarium specimens collected in this region is an invaluable source for a comprehensive assessment of the state of the ecosystems of Karabakh and Zangezur over the past 30 years. This is the purpose of the study of the genus Campanula which is widespread in the northern hemisphere and is of special importance for the flora of the Caucasus. According to literature, 110 species of this genus are found in the Caucasus, and 46 - in Azerbaijan. The history of the study of the genus, its geographical distribution, as well as the taxa found in the flora of Karabakh and Zangezur were compared, and the herbarium data stored in the BAK were analyzed. It was found that the subgenus Campanula L., which is the richest of the subgenus in terms of the number of species of the genus, includes 11 sections. And 18 taxa belonging to 7 sections are found in the flora of Azerbaijan, 11 taxa of which are found in the flora of Karabakh and Zangezur. During the examination of herbarium specimens of the genus Campanula L. stored in the BAK, it was found that 20 herbarium specimens belonging to 5 species were collected from Karabakh region.

Бюллетень науки и практики / Bulletin of Science and Practice

Campanula L. (Bellflower) is the largest genus of the Campanulaceae family which comprises more than 400 species . Representatives of the genus are perennial, rarely annual herbs that can be found in various habitats, including subalpine and alpine belts of mountains, forests, meadows, partly deserts and steppes. The genus Campanula is widespread mainly in the northern hemisphere, and this genus is of special importance for the flora of the Caucasus. So, many endemic species of the genus are found here. According to literature data, 110 species of the genus are found in the Caucasus and 46 in Azerbaijan [3]. In “Synopsis of the flora of the Caucasus” [12] authors noted that Campanula genus includes 11 subgenera and among these subgenus Campanula L. is the richest in the number of species. From 18 taxa of this subgenus which indicated for the flora of Azerbaijan 11 taxa are found in the flora of Karabakh and Zangezur [13].

According to the botanical-geographical division of Azerbaijan, the territories of Karabakh and Eastern Zangezur mainly cover the central and southern part of the Lesser Caucasus. It is bordered by Armenia by covering the borders of the administrative regions of Lachin, Gubadli and Zangilan from the southwest, the Murovdagh ridge from the northwest, Injachay from the north, the Karabakh plain from the northeast, the Mil plain from the east, the Karabakh ridge from the west; from the south it extends to the state border with Iran with the territories included in Jabrayil, Zangilan and Fuzuli administrative regions according to its geographical position.

It is covering the borders of the administrative regions of Azerbaijan (Lachin, Gubadlin and Zangilan from the southwest) which borders with Armenia, the Murovdag ridge (from the northwest), Injachay (from the north), the Karabakh plain (from the northeast), the Mil plain (from the east), the Karabakh ridge (from the west); from the south it extends to the state border with Iran with territories that are geographically included in the Jabrayil, Zangilan and Fuzuli administrative regions of Azerbaijan.

Western Zangezur, which is a part of the ancient historical Zangezur district of Azerbaijan, covers Gafan (at present Sunik province or marzi), Gorus (at present Sunik province or marzi), Garakilsa (at present Sunik province or Sisian included in marzin), Mehri (at present Sunik province or Megri included in marzin) administrative regions of Armenia and it borders with Azerbaijan by covering the borders of Zangezur ridge (from the west) and southwest (Ordubad, Julfa and Shahbuz districts of Nakhchivan MR), Kalbajar (from the northeast), Lachin, Gubadli (from the east) and Zangilan (from the southeast) administrative regions and from the south it borders with Iran, extending to the Araz River (Figure 1).

The study of the flora of Karabakh and Zangezur is closely related to various expeditions to the region for the purpose of studying the flora and nature of the Caucasus in general. According to the herbarium specimens collected from the territory of Karabakh and Zangezur stored in different collections and also literature data it is clear that the first botanist to visit this region was A. I. Shovic (1829), later R. F. Hohenacker, F. A. Buze, G. I. Radde, Y. S. Medvedev, V. I. Lipsky, A. A. Lomakin, B. B. Grinevechki and others has traveled [2].

Plant samples collected by G. I. Radde in 1890 and by A. A. Lomakin in 1895 mainly belongs to Zangezur, Shusha and Khojavand, and a relatively small number belongs to Jabrayil region and Nakhchivan. Q. I. Radde also visited some mountains around Goycha Lake [9].

Figure 1. The map of Karabakh and Zangezur territories

Plant samples collected from these areas: Symphyandra armena (Steven) A. DC. — in Shusha and Zangezur cliffs (by Lomakin and Radde); Symphyandra zangezura Lipsky — mainly in the upper forest zone in the southern part of Zangezur (for example Khustup mountain) (by Lomakin); Campanula sibirica L. — on the rocks in Shusha, Ballica, Gorus, Zabukh, etc. (by Lomakin and Radde); Campanula latifolia L. — Kharar village in the forest (by Lomakin); Campanula rapunculoides L. — in Ustupi village (by Radde); Campanula bononiensis L. — in Kharar, Shurnukhu and Bichenak villages, in the forest (by Lomakin); Campanula glomerata L. — in Shusha (by Lomakin); Campanula bayerniana Rupr. — among the stones (by Lomakin) in Parichingil [9].

After 1917, in addition to floristic studies also geobotanical studies were carried out to study the vegetation of forests and grasslands in Karabakh and Zangezur. During the study of mountain xerophytes of the southern part of the Lesser Caucasus 899 species included in this group were recorded during the expeditions organized to: in 1928-1929 along the southern and western shores of Lake Goycha by T. Heydeman, O. M. Zedelmeyer, N. I. Kuznesov, A. A. Grossheim and others, in 1930, Karabakh (Shusha), in 1931, the highlands of Kalbajar, as well as Lachin mountains (up to the village of Minkend), in 1935 to Khojavand region, Ziyarat mountain and surrounding peaks. 10 species of these, belonged to the Campanulaceae family. These species were found on rocks and grouped as Campanuletum and Symphyandretum phytocenosis [8].

Plant samples were collected during an expedition organized to the western slope of the Zangezur range, as well as its southern and high-mountainous part (between Kapicic mountain in the north and Shikhyurdu mountains in the south) in 1933. Scientists Y. Isayev, Ch. Gurvich, N. L. Antonov, A. Grossheim participated in the collection and determination of these samples. Among these samples also were plant species belonging to the Campanula L. genus and they were grouped as follows: on rocks in subalpine zone (3-4 km to north-east from Urmus) — Symphyandra zangezura Lipsky (in rock crevices, stony — rocky slopes); S. armena (Steven) A. DC. (Urmus — Mazra, in rock cracks); also, S. zangezura Lipsky and Campanula glomerata L. in semi-open phytocenoses in Thymeto-Festucetum and Tragacanth astragal phytocenosis [7].

In the IV volume of “Flora of the Caucasus” it was mentioned that 15 species of the subgenus Campanula are distributed in the Caucasus and 8 in Zangezur [6].

In multivolume of “Flora of the USSR”150 species of the Campanula genus and 7 species of the Symphyandra genus was studied by A. Fyodorov. 18 of them belonging to the Campanula subgenus and 3 species of the Symphyandra A. DC. genus was noted to be distributed in Karabakh and Zangezur [4].

The taxonomy of the Campanula L. species found in Azerbaijan flora was studied by A. Fyodorov in the multivolume “Flora of Azerbaijan” [3].

He gave description and distribution of 19 species of Campanula subgenus in Volume VIII. It is mentioned that 16 species distributed in Karabakh and Zangezur belong to the Campanula subgenus, and 3 species belong to the Symphyandra A. DC. genus [3].

Later the Campanula L. genus was not taxonomically revised as an independent genus but was studied floristic and geobotanically in the vegetation composition of the determined area [14, 15].

In June 1985, A. D. Mikheev described a new species of Campanula L. from the broadleaf forest on the right bank of the Tartar River in northern Karabakh — Campanula karabaghensis Mikheev [10].

Caucasian species of the genus Campanula L. have been studied by many researchers But, Azerbaijani bellflower species have not been studied from a morpho-systematic point of view. Only A. Nasirova investigated Campanula species distributed in Nakhchivan [11].

Since 2018, studies have been started in order to clarify the phylogenetic relationships and to carry out a systematic review of species belonging to the Campanula L. subgenus found in the flora of Azerbaijan. There are given the analysis of data (history of the study of genus, geographical distribution, including herbarium specimens in the BAK herbarium fund, etc.) and morphological descriptions of species of Campanula L. subgenus distributed in the flora of Karabakh and Zangezur [14, 15].

Materials and Methods

In this study, various floras [3, 4, 6, 8] and other literary materials [9, 11, 13] were analyzed from taxonomic and nomenclature points of view (Table 1).

As a result of the comparative analysis of the taxonomic composition of the Campanula subgenus found in the flora of two neighboring areas, Jaccard’s similarity index was determined [7] and dendrogram of cluster analysis was drawn by UPGMA method (Unweighted Pair Group Method with Arithmetic mean) [8].

1:1300000 scale thematic map of the studied area was prepared using ArcGIS 10.8 software (Figure 1). Also, the herbarium specimens of the Campanula L. genus stored in the BAK herbarium fund [1] of the Institute of Botany and digitized in the virtual herbarium database [5] were revised. Among the herbarium specimens stored in the herbarium fund, specimens belonging to the subgenus Campanula species collected from Karabakh and Zangezur territories were analyzed, the area where they were collected, the date of collection, as well as the researchers who collected and identified them, etc. listed in the form of a table (Table 2).

Because those areas were occupied for a long time, no expedition was organized there, and no new herbarium specimens were collected .

Results and Discussions

As a result of analysis of literature materials, floras and synopses about the Campanula L. genus, as well as revision of herbarium specimens stored in the BAK herbarium fund and digitized in the virtual herbarium databases, taxonomic analysis based on nomenclature changes made as a result of research conducted in recent decades, to the taxa of the subgenus Campanula found in the flora of Karabakh and Zangezur belongs: Campanula latifolia L., Campanula rapunculoides L., Campanula bononiensis L., Campanula caucasica M. Bieb., Campanula armena Steven, Campanula zangezura (Lipsky) Kolak. & Serdyuk., Campanula bayerniana Rupr., Campanula coriacea P. H. Davis., Campanula glomerata L., Campanula glomerata subsp. caucasica (Trautv.) Ogan., Campanula glomerata subsp. oblongifolia (C. Koch.) Fed., Campanula sibirica subsp. hohenackeri (Fisch. et C. A. Mey.) Damboldt.

It was determined that 11 taxa, including 8 species and 3 subspecies, are distributed in each of the territories of Karabakh and Zangezur, and were analyzed their similarities with representatives of the Campanula subgenus found in flora of Nakhchivan in Table 3.

The taxonomic composition of the Campanula subgenus found in flora of Karabakh and Zangezur was comparatively analyzed using Jaccard’s similarity coefficient. The results of the preliminary studies showed that 6 species ( C. glomerata L., C. latifolia L., C. rapunculoides L., C. bononiensis L., C. armena Stev., C. bayerniana Rupr.) belonging to this genus are common for a flora of Nakhchivan, western and eastern Zangezur and Karabakh. This is approximately 40% of the total number of species distributed in these territories. In order to compare the similarity of Campanula L. species distributed in these territories, a similarity index was determined using the Jaccard similarity coefficient method (Figure 2).

During the examination of the herbarium materials stored in the Herbarium Fund (BAK) of the Institute of Botany of the Ministry of Science and Education of Azerbaijan Republic among the herbarium specimens of the species C. armena Steven (= Symphyandra armena (Steven) A. DC.), C. bayerniana Rupr., C. bononiensis L., C. glomerata L., C. rapunculoides L., C. latifolia L. were also found herbarium specimens collected from Karabakh and Eastern Zangezur territories. Materials belonging to the C. armena Steven species were collected from Khojavand, Kalbajar, Jabrayil, Lachin, Shusha regions, only one herbarium specimen belonging to C. bayerniana Rupr. were collected from Kalbajar region, herbarium specimens of C. bononiensis L. were collected from Kalbajar and Khojavand districts, one herbarium specimen of C. glomerata L. species were collected from Kalbajar district, herbarium materials of C. rapunculoides L. species from Khojavand, Kalbajar, Jabrayil districts and herbarium specimens belonging to C. latifolia L. were collected from Khojavand and Kalbajar regions. Scientists such as T. Heydeman, A. Grossheim, Y. Isayev, M. Rahimov, J. Gurvich, A. Kolakovskiy, A. Khadarin played a great role in the collection and identification of these materials (especially T. Heydeman). The visits of these scientists to the Karabakh region coincided with the years 1929-1937.

During the revision of the herbarium materials stored in the Herbarium fund of the Botanical Institute of MSE AR (BAK), it was determined that herbarium materials of the following species were collected from the territory of Karabakh and East Zangezur:

A perennial plant has a dense, woody root. The stem is erect, from 20 cm to 1.3 m in height. Basal leaves are long-stalked, ovate-lanceolate or ovate, 6-15 x 2-7 cm, heart-shaped at the base, toothed at the edges and the apex is sharpened. The base of the stem leaves is elliptic, narrowly eggshaped, 4-10 x 0.7-4 cm., rounded or wedge-shaped or truncated at the base, the edges are toothed, the apex is sharpened. The lower leaves are long-stalked, the upper ones are sessile, narrow and small. Flowers are sessile, clustered in a panicle, sometimes with additional, simple sessile panicles located in the axils of the lower and middle leaves. The central flower that blooms first is small. The parts of the calyx are square or linear-triangular. The corolla is purple, blue-purple or blue (rarely white), tubular-bell-shaped, 1.5-2.5 cm. The capsule is hemispherical or obovate-conical, about 4.5 mm. The seeds are oblong, compressed, 1-1.5 mm in size. Flowering: VII-VIII-IX months, Fruiting: IX-X months.

  • C. latifolia L., Sp. Pl.: 165. 1753 — Giant bellflower [3].

Heterotypic synonym: Campanula megrelica Manden. et Kuth.

A perennial plant. The root is fibrous, milky and juicy. Stem straight, simple, glabrous or sparsely hairy, height is 1 m. or more. Leaves are bare, sometimes blunt, 7-12 cm in length, 3 cm. in width, it is light in color from the lower part, the edges of the leaf are unevenly double-serrated. Leaves around the stem are ovate-oblong, with long teeth compared to the leaves of the stem; lower stem leaves short-stalked, ovate, acuminate; upper leaves are sessile, relatively narrow and almost completely marginate. The flowers are large, pedunculate, located singly in axils of upper leaves; erect, narrow, forms spike inflorescence. The calyx is completely naked, pear-shaped, large, blackish, with long, sharpened teeth, usually serrated at the edges; noticeably shorter than the large corolla (up to 6 cm long). The corolla is blue, or sometimes almost white, funnel-shaped, with long soft hairs inside. Stamens widened at the base, bearded; the column is slightly shorter than the corolla, with 3 (sometimes 2) stigmas. The capsule is egg-shaped and opens with 3 holes. The seeds are egg-shaped, light yellow in color. Flowering: VI-VII months, Fruiting: VII-VIII months.

Taking into account that most of the collected herbarium specimens belong to the years 19311937, it is appropriate to re-collect new herbarium specimens from those areas and it is necessary to study them. Also, the nomenclature changes made as a result of the research conducted in the last decades show that it is important to revise both taxonomically and molecularly the species of the Campanula L. subgenus of the Campanula L. genus found in the flora of Azerbaijan. For this reason, within the framework of our ongoing research in the near future, it is planned to organize expeditions to the administrative regions included in the Karabakh and Eastern Zangezur and to study of their flora.
