    Raj et al. Journal of Ethnobiology and Ethnomedicine (2018) 14:8 DOI 10.1186/s13002-018-0208-9 RESEARCH Open Access Indigenous uses of ethnomedicinal plants among forest-dependent communities of Northern Bengal, India Antony Joseph Raj4* , Saroj Biswakarma1, Nazir A. Pala1, Gopal Shukla1, Vineeta1, Munesh Kumar2, Sumit Chakravarty1 and Rainer W. Bussmann3 Abstract Background: Traditional knowledge on ethnomedicinal plant is slowly eroding. The exploration, identification and documentation on utilization of ethnobotanic resources are essential for restoration and preservation of ethnomedicinal knowledge about the plants and conservation of these species for greater interest of human society. Methods: The study was conducted at fringe areas of Chilapatta Reserve Forest in the foothills of the eastern sub-Himalayan mountain belts of West Bengal, India, from December 2014 to May 2016. Purposive sampling method was used for selection of area. From this area which is inhabited by aboriginal community of Indo-Mongoloid origin, 400 respondents including traditional medicinal practitioners were selected randomly for personal interview schedule through open-ended questionnaire. The questionnaire covered aspects like plant species used as ethnomedicines, plant parts used, procedure for dosage and therapy. Results: A total number of 140 ethnomedicinal species was documented, in which the tree species (55) dominated the lists followed by herbs (39) and shrubs (30). Among these total planted species used for ethnomedicinal purposes, 52 species were planted, 62 species growing wild or collected from the forest for use and 26 species were both wild and planted. The present study documented 61 more planted species as compared to 17 planted species documented in an ethnomedicinal study a decade ago.

    Revista Brasil. Bot., V.34, n.3, p.343-358, jul.-set. 2011 Morphological, anatomical and biochemical studies on the foliar galls of Alstonia scholaris (Apocynaceae) SUSY ALBERT1,2, AMEE PADHIAR1, DHARA GANDHI1 and PRIYANKA NITYANAND1 (received: April 23, 2010; accepted: June 30, 2011) ABSTRACT – (Morphological, anatomical and biochemical studies on the foliar galls of Alstonia scholaris (Apocynaceae)). Morphological, anatomical and biochemical alterations in foliar galls of Alstonia scholaris R. Br. induced by the insect Pauropsylla tuberculata (Psyllidae) are described and quantified. Galls occur isolated or agglomerated on the abaxial surface of the leaf. The insect along with the egg deposits some physiologic fluid which act as a stimulant for the induction of the gall. This stimulus brings about hypertrophy followed by hyperplasia of cells next to the location of the deposited eggs. The psyllid presents three nymphal instars, from eclosion of the egg to the adult. Hyperplasia in the palisade cells is very distinctly noticed. Hypertrophy followed by hyperplasia takes place and brings about elevation of hypodermal and palisade parenchyma which undergoes repeated anticlinal divisions. Neoformation of phloematic bundles were distinctly noticed close to the site of infection. With an increase in the growth of the gall, chlorophyll content in the gall tissue decreases. A steady increase of sugar content is noticed. The immature galled tissue showed almost two fold increases in the protein content. The mature galled tissue showed a very high increase in the proline content compared to the immature galled tissue indicating a stressed condition of the galled tissue. Key words - hyperplasia, hypertrophy, Pauropsylla tuberculata RESUMO – (Estudos morfológicos, anatômicos e bioquímicos em galhas foliares de Alstonia scholaris (Apocynaceae)).

ABSTRACT The Lower Gangetic Plains particularly from Dakhineshwar to Uluberia, West Bengal was investigated for the taxonomic and ecological analyses of its naturalized vegetation. The physicochemical studies of soil were also performed from this site. It was observed mangrove plants prevailed at zones where higher percentage of silt was present, while inland plants were grown where percentage of sand and clay were higher. A total of 95 plant species were recorded and their phytoclimatic study was done and the result revealed that percentage of phanerophytes was maximum among others. From phytosociological study it was observed that mangrove associates such as Cryptocoryne ciliata and Oryza coarctata showed highest IVI values, on the other hand Cynodon dactylon was dominated at non-mangrove site. The present analyses indicated existence of two distinct plant communities in the site with more or less stable vegetation pattern.

    Rufford Small Grant: Progress Report - 2 2012 Project Title: Assessing the diversity of national red listed vascular plants and hotspots identification at Rema- Kalenga Wildlife Sanctuary, Bangladesh Project leader: Md. Qumruzzaman Chowdhury Project summary Rema-Kalenga Wildlife Sanctuary (RKWS) is one of the most critical protected areas (PA) in Bangladesh where a large number endemic plant and animal species have already disappeared due to severe anthropogenic disturbances. Therefore, assessment of red listed species diversity and identification of biodiversity hotspots are important in conservation management. Hence, the general objective of the work is to develop baseline information on the occurrence and diversity patterns of the national red listed vascular plant species in the PA to foster conservation of these threatened components of nature. Specific objectives (I) Quantification of red listed species diversity and exploration of their distributional patterns in different habitats. (II) Identification of hotspots within the PA. Results Diversity of Red Listed Vascular Plants We found a total of 66 red listed vascular plants of 35 families and 55 genera in the Rema- Kalenga Wildlife Sanctuary (Table 1). Plantation forest consists of 47 species of 42 genus and 28 families. Natural forest has 17 unique species. Highest richness value (18) was found in plot 2 of natural forest and lowest value was observed in sample plot 4 (Figure 1a). Out of 50 plots in 1 Rufford Small Grant: Progress Report - 2 2012 plantation forest 4 plots did not have any red listed species. Richness value ranged from 0 to 14 with a mean value of 5.32. In terms of alpha diversity, mean values were 1.64 and 1.07 for natural and plantation forests, respectively (Figure 1b).
