Sacred groves are distinctive examples of biotic components as genetic resources being preserved in situ and serve as secure heavens for many endangered and endemic taxa. From this point of view, the biological spectrum, leaf spectrum and conservation status of the current sacred grove vegetation, SBT (Swarga Bauri Than) in Jhargram district of West Bengal, India, have been studied. The area's floristic study revealed that SBT’s angiosperms were varied and consisted of 307 species belonging to 249 genera, distributed under 79 families of 36 orders as per APG IV. Fabales (12.05%) and Fabaceae (11.73%) are the dominant order and family in terms of species wealth. Biological spectrum indicates that the region enjoys “thero-chamae-cryptophytic” type of phytoclimate. With respect to the spectrum of the leaf size, mesophyll (14.05%) was found to be high followed by notophyll (7.84%), microphyll (7.19%), macrophyll (7.84%), nanophyll (6.86%), leptophyll (6.21%), and megaphyll (2.29%). The study area, being a sacred grove, it has a comparatively undisturbed status, and the protection of germplasm in the grove is based on traditional belief in the social system.

The plant species of Hazarnoe Forest of District Malakand, Khyber Pakhtunkhwa, were evaluated floristically from April 2016 to November 2017. Of the total 240 reported plant species, 38 were monocots, 196 dicots which belongs to 85 families and 188 genera respectively. Poaceae was the leading family contributed 20 species. Family Asteraceae contributed (14 spp.), Lamiaceae (13 spp.) while Papilionaceae and Solanaceae each with 10 species. Of the total plant taxa perennials were 161 species compared to annuals (73 spp.) and biennials (06 spp.). The dominant growth form was herbs that contributed (108 spp.) followed by trees (50spp.) and shrubs (45 spp.) respectively. Phanerophytes were the dominant life-form (92 spp.) whereas leaf size spectrum of microphyll was reported as abundant in the overall floristic. Phanerophytes and microphyll leaf size was the dominant life forms which show typical climate of subtropical region governing the area. Conclusion of study was that the vegetation of the area is under heavy biotic pressure and need proper conservation.

Social practices play a crucial role in the conservation of the environment and biodiversity. The present study was carried out to explore the plant resources, their biological spectrum, leaf size spectra, conservation status and management of the existing vegetation of a sacred grove, namely Kalua Sarnd Than (KST) in the Jhargram district of West Bengal in India. Floristic elements of the study area revealed that the vegetation was diverse and composed of 150 species belonging to 141 genera distributed over 60 families under 31 orders according to APG IV classification. The study area being a sacred grove is fairly undisturbed and protection of germplasm in the grove is maintained through the traditional beliefs. The present study, thus, could be used as an inspiring example in India for other sacred groves for phytoclimatic study.

Tetralophozia setiformis is a widespread species occurring usually without organs of sexual and asexual reproduction. Gemmae of Tetralophozia setiformis were observed for the second time in Russia and Eurasia in the Northern Urals, Komi Republic. They form compact masses over upper leaves. The compact masses consist largely (70 %) of immature gemmae. Description of gemmae and gemmiparous shoots from the Northern Urals and their comparison with those from the other known localities, namely British Columbia (Canada) and the Murmansk Region (European Russia) were carried out. The gemmiparous plants of T. setiformis from the Northern Urals have approximately the same width as plants without gemmae but they are shorter. The leaves of gemmiparous plants from the Northern Urals are similar to leaves of gemmiparous plants from British Columbia. The leaf shape in upper part of the gemmiparous shoots varies from the typical to ± modified from gemmae production. These leaf shape transitions include reduction of leaf size and lobe number from 4 to 2–3, suppression of development and disappearance of characteristic teeth at the base of sinus. Gemmae size (17 × 22 μm) of plants from the Northern Urals is within variability recorded for plants from the Murmansk Region and British Columbia.


For identification of varieties, it is desirable to use genetically predetermined traits that are decisive for the varietal identification of the distinguishing characteristics of the varieties production and new genotypes for selection. The presence a complete evaluation of the selection samples a particular crop is the basis for the formation of informative databases characteristics the varieties of standards used in plant examination to determine the level of expression a characteristic particular genotype according to the code of their manifestation. For the 20 traits we used to identify, we identified 6 least volatile, highly trait-stable traits over the years of study to identify. These are: “coloring of the pubescence of the main stem”, “the size of the lateral leaf”, “the intensity of green leaf color”, “flower color”, “the intensity of brown bean color”, “basic color of the seed coat”. The other 14 traits are highly variable and unstable among varieties, but may be significant under certain conditions. According to the results of the research we have determined the conformity of the collection varieties by code graduation. In the study, we selected varieties with corresponding codes of attributes of the reference varieties the UPOV technique. On the basic of the color the pubescence of the main stem, 36% varieties are with grey stem pubescence. Among the standards: Apache, Alaric, Talon according to the grey color of the pubescence, we identified varieties Zolotysta, Ozzie, Diona. The 2947 564/84, Stepnaya-90, Knyazhna. The lateral leaf size is a sign that affects the increase in green mass of plants and subsequently on productivity. Graduation of the sign small size of leaf had varieties: Zuma, Ksenya; middle – Heinong 37, Yuh-30; large – 2947 564/84, Vinni, DSS 2504. The following is a sign of the intensity of leaf plate, which is divided by gradation into light, moderate and dark. Among our samples with a light degree of color, we can distinguish Diona, Sribna Ruta, and Zuma. For varieties with moderate gradation of color are selected: Perlyna, 93/99, Knyazhna. To the dark color of the leaf plate we attributed the varieties: Stepnaya-90, Ozzie. Among the varieties we studied of the basics of flower color 37% varieties are with a white flower, and 63% with a purple. According to the varieties of standards: Chandor, Cresir, Toreador to the white color of the flower we attributed varieties Knyazhna, Ozzie, Zolotysta. With the purple color of the flower we have selected varieties: 93/99, Zhemchuzhna, Heinong 37. On the basis of the intensity of brown color bean, which characterizes the generative organs of the plant, is divided into weak, moderate and strong, but the other identifiers there are gradations: sandy, gray, light brown, brown and dark brown, so we decided what would be better identify by color gradation. To the sandy color of the beans we attributed varieties Perlyna, Yuh-30; gray – Sribna Ruta; light brown – Kobza, Knyazhna; brown – Ksenya; dark brown – Zhemchuzhna, Vinni. Important features that identify the description of varieties include basic color of the seed coat, which affects the taste of the seeds. In particular, the seeds are divided by color into yellow – Kobza, Yuh-30; yellow-green – Vinni, Luch Nadezhdy; green – Heorhina; light brown – 2947 564/84, brown – DSS 2504; dark brown – 2974 YS-24 and black color – not detected. Following the results of the previous collection of soybean varieties from the morphological sings of vegetative, generative organs of plants, it was possible to identify varieties with stable manifestation of standard identifying sings of soybean. Collection varieties with one standard characteristics: Heinong 37, Luch Nadezhdy, DSS 2504, 2974 YS-24; two signs: Zolotysta, Diona, Stepnaya-90, Zuma, Ksenya, Heorhina, Sribna Ruta, Perlyna, 93/99, Zhemchuzhna; three signs: Ozzie, 2947 564/84, Yuh-30, Vinni, Knyazhna.
