The floral diversity of Meghalaya is well reputed for its richness and has been a centre of attraction for many botanists. The presence of a large number of primitive flowering plants has prompted Takhtajan (1969) to call it the Cradle of Flowering Plants’. Meghalaya harbours about 3,128 species of flowering plants and contributes about 18% of the total flora of the country, including 1,237 endemic species (Khan et al 1997). A wide variety of wild cultivable plants, edible fruits, leafy vegetables and orchids are found in the natural forests of Meghalaya. However due to overexploitation, deforestation and habitat destruction many endemic and threatened species are now mainly confined to the protected areas and sacred groves. The region is a habitat for many botanical curiosities and botanical rarities. Among insectivorous plants Nepenthes khasiana Hk. f. and two species of Drosera i.e, Drosera peltata Sm. and D. burmanii Vahl. are important. Nepenthes khasiana is endemic to Meghalaya and listed in Appendix I of CITES and placed in Schedule VI of the Wildlife (Protection) Act, 1972. The Khasi and Jaintia hills are considered to be the centre of diversity for several primitive families such as Elaeocarpaceae, Elaeagnaceae, Anonaceae, Ranunculaceae, Piperraceae, Menispermaceae, Caryophyllaceae, Lauraceae, Myricaceae, Lazarbiaceae and primitive genera like Sarcandra, Corylopis, Myrica, Magnolia and Michelia.

Mary Beth Adams, ... Jamie Schuler, in Developments in Soil Science, 2019 Temperate evergreen forests Temperate evergreen forests are found in the United States, Canada, Europe, and Asia, in areas that generally receive between 300 and 900mm of rain per year and with seasonal temperature extremes ranging from -40 to 20°C. Climate differences occur between the northern and southern evergreen forests, where in northern areas, winters are commonly long, cold, and snow dominated, relative to the more southern coniferous forests, where precipitation and temperatures are more evenly distributed throughout the year ( Ichoku, 2018). Vegetation includes coniferous-evergreen tree species that produce cones and needles, dominated by spruce ( Picea), pine ( Pinus), fir ( Abies), and hemlock ( Tsuga) species, and the trees retain at least some of their needles year-round. In the southern hemisphere, conifer genera also include Araucaria and Podocarpus, which are widespread and common. Laura Casella, ... Emiliano Agrillo, in Encyclopedia of the World's Biomes, 2020 Conclusions and Conservation Recommendations The evergreen forests of the Mediterranean do not seem to need further efforts in terms of the establishment of protected areas, as shown by the assessments conducted in various protectionist areas (see Red List and Article 17 of the Habitats Directive). However, some management aspects can be addressed in order to improve the ecological function of Mediterranean evergreen forests....
