Introduction

The north-eastern part of the Lesser Caucasus (within Azerbaijan) is one of the richest regions of the Caucasus in terms of biodiversity. There are most types of plants found in Azerbaijan. A number of prominent scientists have conducted research on the formation of flora in the region. According to research, there are more than 12 000 species of ferns (Filicophytina, Polypodiophyta) in the world, especially in the tropical forests of mountainous areas. Paleobotanical studies show that this is a small part of the once widespread Pteridophyta.

The extinction of many large groups of Pteridophyta is associated with climatic, tectonic, and floristic changes in the past geological periods (especially cataclysms in the Devonian, Carboniferous, and Jurassic geological periods). In addition, the main reasons are the expansion of flowering plants, the poor tolerance of ferns to environmental factors compared to flowering plants, and the weak barrier mechanism during the fertilization of germ cells (in natural hybridization).

Material and methodology Basic researches in the study of ferns in the North-Eastern part of the Lesser Caucasus were carried out systematically and consistently by months and seasons of 2015-2020, taking into account the relief of the area, soil and vegetation. Taking into account the width of the area, the richness of vegetation and the diversity of ferns spreading zones, the main advantage in conducting field researches was given to the route method. Zonal distribution and botanical-geographical features of the area vegetation were taken into account during the selection of routes. During the study, a herbarium sample was collected and identified during regular expeditions covering the entire North-Eastern part of the Lesser Caucasus (Ganja, Gazakh, Tovuz, Gadabay, Dashkasan, Goy-Gol and Shamkir).

In the designation of the studied ferns, Flora of the Caucasus, Flora of Azerbaijan, A. M. Askerov&s Ferns of the Caucasus, A. I. Shmakov&s Key of Russian ferns and other works were used [1-9].

Discussion of the research and results As a result of the development of literature and personal field research materials, the Pteridophyta of the north-eastern part of the Lesser Caucasus is characterized by 3 divisions, 5 classes, 13 families, and 39 species of 20 genera [2].

As a result of the analysis of the collected herbarium and descriptor data, Polypodium interjectum Shivas, Polystichum illyricum Hahne, Cystopteris anthriscifolia Fomin., 1 species variety Polystichum aristatum (G. Forst.) C. Presl., 1 new ecotype Adiantum capillus-veneris L., were identified as new for the studied area.

Polypodium interjectum we collected during the first expedition in the Lesser Caucasus on June 24, 2015, from Goygol area, Amirvar village of Dashkesan region and Asrik forest area of Tovuz region (N40°47,462&; E 45°35,636; h 1209 m). It is a new species for the area flora. It is a mesophyte, lithophilic plant of the Euro-Mediterranean area type.

Sivriyarpag q. is a perennial, mesophytic plant, 20-40 cm tall, spore-bearing in July-August, spread in forests and rock crevices. The sorus is arranged in rows on both sides of the veins. The surface of the spores (perisporis) is wrinkled. 2n = 168.

Cystopteris anthriscifolia was collected near the Amirvan village of Dashkesan region, from the Asrik forest of Tovuz region, near the Bayan village of Ganja-Dashkesan highway and around the Khoshbulag and included into the flora as a new species.

The height of the plant is 30 cm, the rhizome is covered with an elongated, narrow black cover. Vaya is an ovoid, usually dark green, soft herbaceous plant. The boards are elongated and wide, alternately arranged, with double or triple feathery sections. The axis is thin, dark brown or dark red with a bright color and is bare. The last row of segments is on a thin woolen stalk and the sides are rounded. The upper edges are serrated. Spores are located transversely at the end of the wings. The soruses are elongated. Spores grow in June-August. It is a moist-lithophilic, mesophytic plant associated with tropical flora of cosmopolitan geographical type. Diploid, 2n = 60.

Figure 4. Adiantum capillus-veneris.

Adiantum capillus-veneris was collected twice by us for the first time from the research area in 06.09.2015, a new Alchagboylu-Ganja ecotype of this species was discovered in the vicinity of Amirvar village of Dashkesan region and in the area around the waterfall, among the rocks, together with moss plant (N40°30,594&; E 46°20,494&; h 1086 m). It was collected on 18.04.2018 from a cave, which is an ancient settlement in Dashsalahli village of Aghdam region. It is given by us as a new ecotype for the area flora. This specimen differs from typical Venus hair adiant specimens by its small size and is found in relatively arid habitats.
