All the plant species studied contained stomata and cystoliths, which vary in shape and size. Actinocytic stomata type was present in only one species (Ficus sp. 1). Anomocytic type in three, and paracytic in four species. Stomatal frequency calculation revealed that the highest frequency was reported in F. hispida and the lowest in F. rumphii. There is also an indication that semi-coriaceous and coriaceous glabrous leaved species of Ficus are linked to the stomatal characters. The results have shown the presence of stalks in all the cystoliths of various sizes. Different shapes such as star-shaped, bean-shaped, solitary, round, and oblong cystoliths are recorded during the study. The largest cystoliths were found in F. rumphii, where its spinous surface is quite distinct from all other species and can be rec...

The field and herbarium techniques were followed to obtain the essential information on the use of medicinal plants. The collected plant species were identified with the consultation of taxonomic literature Floras and Herbaria. Altogether 16 medicinal plant species belonging to 13 families were reported to be used by the Monpa community of this region. Leaves (32%) were the most frequently used plant part, while the flowers (5%) were the least. A total of 16 different medical conditions were reported to be neutralized using these plants. As it was claimed by the locals, these medicinal plants are considered to have no side effects and have multiple health benefits. The plant species Oenanthe javanica, with the highest CIs (Cultural Importance Index) and URs (Use Report) score was reported to be the culturally most significant plant among all the medicinal plants used by the Monpas of this region. Moreover, ICF (Informants Consensus Factor) values specified that there was high agreement in the use of plants in the headache and gastro-intestinal ailments category among the users. The rich bio-resources of this region may be further explored to widen the potentiality of herbal medicines.

Plants are a reservoir of large numbers of microorganisms known as endophytes (Bacon and White, 2000). De Bary (1866) originally introduced the word "endophyte", with 'endo' meaning inside and 'phyte' meaning plants. So, endophyte refers to the organisms that live within the plants (Wilson, 1995). There have been diverse ways of defining the word 'endophytes'. Still, the most accepted definition was given by Stone et al., (2000), which defines endophytes as those organisms whose "infections are inconspicuous, the infected host tissues are at least transiently symptomless, and the microbial colonization can be demonstrated to be internal".

Eastern Himalayas, a biodiversity hotspot is not only a home to the world’s highest mountains but is also amongst the highest diversity rich areas of the world. The easternmost part of the Indian Himalayas harbors many special vegetation types, depending upon altitudinal and climatological stratification. Arunachal Pradesh is one of the richest states in the region in terms of biodiversity, owing to its unique geographical position and altitudinal gradients. The article ventures preliminary account of flowering plant diversity of Nagula wetland complex of Arunachal Pradesh, which has more than 100 alpine freshwater lakes fed by melting snow. The altitude ranges from 3,500–4,500 meters above mean sea level. The study recorded a total of 106 species, falling under 68 genera and 32 families. Asteraceae is the most dominant family followed by Orobanchaceae, Gentianaceae, etc. If the area’s natural vegetation is conserved without any disturbance that will maintain not only the pristine beauty but also the rich and original biological elements of the area. A high proportion of angiosperms of this area can be adopted for ornamental gardens, and some others can be tested for their medicinal properties.
