The existence of Dioscorea wallichii Hook. f. (Dioscoreaceae) is noted first time from the forest floor of Tripura, North East India. The tuber of this plant is used as a vegetable as well as a medicinal purpose by the indigenous peoples of the state. Reang communities of Tripura used tuber of this plant for stomach pain and Jamatia community have eaten this tuber with honey for refreshment and also increase physical fitness. It is widely distributed throughout forest floor as well as the degraded land of the state.

  Cleome genus includes 601 plant species from the family Cleomaceae. Of more than 600 plants, 206 (34.3%) plants are having accepted species names. Cleome gynandra Linn. is a well-known medicinal plant with traditional and pharmacological importance. A good number of secondary plant metabolites have also been isolated from different parts of C. gynandra. Our investigation confirms two mutant varieties of C. gynandra exists in India. Accordingly, the objective of this study was designed to critically evaluate the pharmacological and phytochemical evaluation of C. gynandra of two mutant variety, to provide a consolidated platform for research potential of both the mutant varieties of C. gynandra. Careful scrutiny reveals that the plant possesses a huge range pharmacological applications, such as anti-inflammatory, free radical scavenging, anticancerous, immunomodulator, and antidiabetic agents. To arrive its pharmacological importance the published papers also shown an enormous amount of phytochemicals endorsement. Scientific perusal reveals different parts of the plant has an immense medicinal importance which proofs its traditional use round the glove. But in North-Eastern region of India, the same plant abundantly found in pink mutant variety. To date, there is not much research investigation for this mutant variety to validate its pharmacological importance. Therefore, research needs to scrutinize and compare the medicinal claims of the pink mutant variety in the bio-diverse region of North-East India.

Land use is the human utilization for money, private, recreational, conservational and administrative purposes. The idea of land use is firmly interwoven with human network advancement. Examples of human turn of events and land use have molded the earth legitimately and internationally since ancient occasions. Current improvement designs, along with highlights of the common habitat and the outcomes of past advancement exercises, decide future advancement openings, and furthermore the requirement for rebuilding or upgrade of natural assets. North-east India is the abode of highly endemic flora and fauna preserving the pristine environment with little human interference until recent times. However, for past two decades a drastic change in the land use pattern in the region has been observed which may threaten the fragile ecological balance of the region. Tripura, known as one of the seven sisters, is a bamboo resource and second largest rubber producer in India. Tripura has the highest number of primate species found in any Indian state. However, as compared to its other sisters, the state is economically backward. The land use of the state is undergoing rapid change which is facilitated to a great extent by rapidly increasing population. The present paper deals with the changing land use of Tripura especially in the last two and a half decades. The objective of the study is to analyse the changing land use of the state in general and changes in agricultural and non-agricultural land use in particular based upon the data collected from secondary sources like Statistical Abstract of Tripura, Population Tables of Census 1991, 2001 and 2011 along with the information collected from various government websites.

Sumi (also known by its exonym ‘Sema’) is a Tibeto-Burman language spoken in Nagaland, North-east India. It is one of the major languages of the state, with an estimated 242,000 speakers living primarily in Zunheboto district, as well as in the major cities of Kohima and Dimapur. Bradley (1997) places Sumi (referred to as Sema), among the ‘Southern Naga’ languages, which include Angami (also known as Tenyidie) and Ao, in contrast to the ‘Northern Naga’ languages such as Konyak and Nocte. Burling (2003) offers a more conservative classification, placing Sumi (referred to as Simi) in an ‘Angami-Pochuri’ group containing Angami, Chakhesang (Chokri and Kheza) and Mao. Four main dialects of Sumi have been identified: the Western dialect, the Eastern dialect, the Chizolimi dialect, and the Central dialect. The Central dialect is the standard dialect used in published works of Sumi (Sreedhar 1976: 4–5).

Gnetum gnemon L. (Gnetaceae) is used traditionally for treating malaria related fever by indigenous people of North East India. In our preliminary study, the ethanol extract of G. gnemon leaves showed promising antiplamodial activity against Plasmodium falciparum chloroquine sensitive (3D7) strain in vitro with an IC50 value of 29.4 μg/mL. Therefore, it was further investigated, and by following a bioassay guided approach, 2,3-dihydroxypropyl icosanoate (1), oleic acid (2) and ursolic acid (3) were isolated for the first time from this plant. Compound 3 showed highest antiplasmodial activity with IC50 values of 4.0 and 6.0 μg/mL against chloroquine sensitive (3D7) and resistant (Dd2) strains of P. falciparum, respectively. The antiplasmodial activity of 1 (IC50 9.5 and 11.4 μg/mL) and 2 (IC50 17.6 and 21.1 μg/mL) was moderate. The isolated constituents showed low cytotoxicity against rat skeletal muscle (L6) and human cervical cancer (HeLa) cells. This is the first report on the antimalarial potential of G. gnemon and the isolated compounds may be responsible for its activity. The findings of the study are in line with the ethnopharmacological claim and can be possible leads for future studies.

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.

Leaf Litterfall

Litterfall and its nutrient return in five oak species were studied in the mixed Oak forest in Senapati District, Manipur .Litter production was measured by litter trap method. The total annual litterfall was 958.9 g m-2yr-1.Leaf and non leaf litterfall comprises 76.7 % and 23.3 % of the total litterfall. Maximum litterfall was found in the month of April (193.5 g m-2) and minimum in the month of July (23.7 g m-2).About 70% of the forest floor was replaced each year with turnover time of 1.42 yr.The amount of nutrient return through leaf litter was found to be maximum in Q.polystachya and minimum in C.indica. Nutrients (NPK) concentration of leaf litter of five different tree species was varied among different tree species.
