The study deals with the floristic diversity assessment and vegetation composition analysis in various forest types from Hosur Forest division situated in Eastern Ghats of Southern India, in the state of Tamil Nadu. The study recorded 468 species of plants belonging to 283 genera and 91 families, including Angiosperms (464 species), Pteridophytes (3 species) and Bryophytes (1 species). Of the total, 94 species are trees, 12 are lianas, 70 are shrubs, 34 species are climbers, 194 species are herbs, sedges 7, grasses 21, ferns 3 and 1 species of moss. The five most abundant families in Hosur Forest Division were Fabaceae (45 spp.), Poaceae (34 spp.), Acanthaceae (30 spp.), Euphorbiaceae (28 spp.) and Rubiaceae (25 spp.). The quantitative features such as density and important value index (IVI) varied greatly among forest and in different forest types. In the present study, the diversity index of shrubs and herbs were found to be higher than that of trees. The maximum species diversity was recorded in Southern dry mixed deciduous forest (SDMDF) followed by Southern Thorn Forest (STF) and Southern Thorn Scrub (STS). The species diversity (H) was recorded the highest for SDMDF (5.61) followed by STF (5.18) and the lowest for STS (5.12). The presence of large number of higher girth class tree species and low number of sapling and seedling indicates that the present forests investigated are old and exhibiting low regeneration.

The present paper deals with the study conducted to know the floristic diversity assessment and vegetation composition analysis in various forest types of Dharmapuri Forest division situated in Eastern Ghats of Southern India in the state of Tamilnadu. A total of 352 species of 233 genera and belonging to 79 families were recorded. The quantitative features such as density and important value index (IVI) varied greatly among forest and different forest types. In the present study the diversity index of shrubs and herbs were found to be higher than the tree species. The presence of high number of higher girth class of tree species and low number of sapling and seedling indicates that the present forest is old and exhibiting the low regeneration.

Endemic Plant Species

The endemic flora is the heart of our understanding of the current biodiversity hotspots, and plays a critical role to conceive successful management strategies for global biodiversity conservation. In Iraq territory context, despite its high plant diversity value, the endemicity is still largely under-investigated and there is no updated database of the Iraqi endemic flora. Therefore, this study sets out to present an updated list of the endemic plant species in Iraq, including a quantitative analysis of their floristic analysis, biological life forms, and geographical distribution. This first Iraqi endemic list can be seen as the first step towards better understanding of the floristic diversity, and can play an important role for future conservation priorities. This endemic list was based initially on the classical flora of Iraq and it has been completed and refining according to the floras of the neighbouring countries. To establish an updated list, it has been added all the Iraqi endemic taxa newly described by retrieving it from the botanical papers and taxonomical websites. For each endemic taxa researcher has provided the following floristic baseline: scientific name, family, phytogeographical distribution, elevation range, biological life forms, and IUCN assessment. The results of this floristic investigation present for the first time an updated endemic list of Iraqi plant species which contains a total of 174 endemic taxa(153 species, 11 subspecies, 10 varieties) in 27 families and 75 genera. They represent an endemicity rate of 5.3% of the total estimated flora of Iraq, which constitutes a low level compared to those of neighboring Irano- Anatolian countries. The family Asteraceae, Papilionaceae, Boraginaceae and Apiaceae are the richest flowering families. The life biological forms indicate that a major part of endemic taxa are chamaephytes (44%) and perennial hemicryptophytes (32%) as an adaptation indicator to the dry-harsh environmental conditions of the Irano-Anatolian mountainous areas. These floristic quantitative analysis support the idea that the species richness and endemicity are not uniformly distributed within the altitudinal gradient and phytogeographical districts of Iraq. For instance, a significant part of the Iraqi endemic taxa concentrate on the Zagrosian foothills and the mountain range between 1000 and 1700. The most striking findings were that only one taxon on average per year was newly described for Iraq, over the last 20 years, compared to around 50 taxa for Iran and Turkey confirming its status of the floristic knowledge coldspot. The current findings add substantially to our understanding of the endemism diversity in Iraqi Zagrosian part, and can serve as a base for future floristic investigation and biodiversity conservation studies

The present study emphasizes the diversity assessment of marine Bacillus species with special reference to biosurfactant production, respective gene expression, and discrimination among Bacillus licheniformis and Bacillus subtilis. Among the 200 individual species of eastern coastal plain of Tamil Nadu screened, five biosurfactant producing potential bacterial species with entirely different morphology were selected. Biochemical and 16S rRNA gene sequence analysis suggested that all the said five species belong to Bacillus genera but differ in species levels. Biosurfactant of all the five species fluctuates in greater levels with respect to activity as well as to constituents but showed partial similarity to the commercially available surfactin. The expression of srf gene was realized in all of the five species. However, the sfp gene expression was observed only in three species. In conclusion, both B. licheniformis and B. subtilis demonstrate srf gene; nevertheless, sfp gene was expressed only by Bacillus subtilis.

Rural home garden is an important traditional source of medicinal plants for daily curative uses throughout Bangladesh. Such knowledge is continuing from generation to generation without documentation. An ethnobotanical investigation was conducted through focus group discussions and households’ survey accompanied by field observation to document the indigenous knowledge of herbal medicines being used by the rural communities of Comilla district in Bangladesh. A total of 45 ethnomedicinal plant species belonging to 34 families were found, where trees (37.78%) were the most commonly utilized growth form. Plant resources are used to treat 31 different individual ailments ranging from simple cuts to heart disease. Plants are mainly used to treat dysentery (12 species), cold ailments, cough, and fever (6 species each). For curing ailments, the use of the above ground plant parts was higher (86.44%); particularly fruits (37.29%) and leaves (30.51%) were the most commonly used plant parts. More than half of the medicinal plants are indigenous (71.11%), being edible fruit bearer (48.89%), plants parts suitable for animals and birds (57.78%), and natural regeneration present (64.44%) indicated that medicinal plants play a vital role in biodiversity conservation in the study area.

Endemic Medicinal Plant

Tamil Nadu has rich repository of medicinal plant wealth and equally threatened with several number of factors. There has been enumerated a total of 119 species Red Listed medicinal plants, from which 27 species have assessed global RL status. Fourteen species have been assigned Critically Endangered (CR) status, 27 species are Endangered (EN), 31 species are Vulnerable (VU) and 10 species are Near Threatened (NT). 18 of these Red Listed medicinal plant species have been recorded in high volume trade in the national level trade study. The present paper analysed the diversity status of endemic medicinal plant diversity,assessment methods, policy terms related to medicinal plant conservation and conservational areas in Tamil Nadu.
