Objective: The aim of present investigation has been carried out for the documentation of ethnomedicinally important aquatic/semi-aquatic plants used by the rural people living in the vicinity of two major wetlands, i.e., Deepor Beel and Chandubi Beel of Western Assam, India. Methods: Intensive field surveys were conducted with the local traditional healers to gather information on medicinal plants used by them in treatment of various ailments. Results: Altogether 31 medicinal plant species belonging to 25 genera and 14 families have been documented from both the wetlands. Of 31 plant species, nine species were found to be used in skin disease, six in jaundice and liver problem, four species each in fever and urinary tract, two species in dysentery and snakebite, and remaining are found to be used in cough, stomach pain, wounds and cuts, neuralgia, toothache, tonsillitis, blood pressure, and smallpox. Conclusion: Unfortunately, the population of ethnomedicinally used macrophytes Nelumbo nucifera, Euryale ferox, and Trapa natans which are rare in these two wetlands are decreasing alarmingly due to commercial exploitation, natural as well as excessive anthropogenic pressure in these two wetlands.

Despite the discovery of several new plant species from India every year, there is dearth of information on species of orchid, especially from the North Eastern Region . As a detailed survey seemed necessary for reliable documentation, we looked into the diversity of orchids in Tripura state. We document the first records from the state for 12 species of orchids, including two genera (Crepidium Tausch and Dendrolirium Blume). Geographical distributions along with detailed descriptions and photographs of the species are provided.

Abstract The present investigation is a novel approach of exploring the endophytic fungal diversity of Elaeagnus latifolia L., an actinorhizal plant species of North-east India and evaluation of its biocontrol potential against Pestalotiopsis theae, the causal agent of grey blight disease in tea. A total of 17 endophytic fungal species belonging to 12 families and 03 orders were isolated from various parts of E. latifolia L. Isolates were identified based on colony morphology, spore and fruiting bodies using microscopical tools and techniques. Nigrospora sp. showed highest species density (0.5) among all the isolates. Isolation frequency was maximum (67%) in case of Fusarium sp., Nigrospora sp., Penicillium chrysogenum and Rhizopus sp. More fungal isolates were obtained from root and stem (47% each) as compared to leaves (29%). Species richness and diversity indices was maximum (15.0) in stem and minimum (9.0) in leaves. Highest Shannon and Simpson diversity index was in stem (2.02 and 0.860 respectively) followed by root (1.979 and 0.847 respectively) and least in leaves (1.494 and 0.75 respectively). Among the isolates tested for plant growth promoting parameters, EF09 (Fusarium sp.) showed positive response for all the tested parameters. The isolate, EF09 also showed maximum antifungal potential (up to 87.1%) against P. theae in poisoned food technique. Enumeration of endophytic fungal diversity of E. latifolia L. holds promises as the putative strains may lead to the isolation of novel bioactive components for use in industry, medicine and agriculture.

Malaria is one of the major causes of mortality and morbidity throughout the developing countries. In spite of considerable advances made in the development of anti-malarial drugs to combat the disease, appearance of the malarial parasite resistance to the drugs one after another, has triggered the researchers to search for alternative agents of better quality. In view of the fact that plant folk medicines have immense value in providing clue for development of drug, an ethnobotanic survey of medicinal plants practiced for the treatment of malaria in North East India, followed by the validity of folklore claims of the plant species was conducted based on the review of reported literatures. Seventy four plant species under 67 genera and 41 families used for the preparation of recipes to treat the disease were included in this communication. For each plant species, botanical and vernacular name, part(s) used, method of preparation and mode of administration of the herbal remedies were provided. Biological activities corroborative of folklore medicinal claims of the plant species were also indicated for the credibility of these folklore claims.
