Book Description
Indian screw pine family Pandanaceae represents three genera, in which genus Pandanus and Benstonea are distributed in two hotspots in India – the Western Ghats and the Northeast Himalayan region. For the first time, Indian Pandanaceae has been assessed for its taxonomic status and phylogenetic relationship. The extensive survey by the authors led to the discovery of three new Pandanus species (two from the Western Ghats and one from the Northeast Himalaya). The present taxonomic revision confirmed total number of Pandanus species to 14 that are distributed in the Southern India (9 species) and Northeast Himalayan region (5 species). Genus Benstonea is represented by two species, one from Southern India and another species common to both regions. A detailed species identification key is given along with conservation status of each species following IUCN Red List Categories and Criteria (2001). The study revealed that, out of 16 Pandanus and Benstonea species, six species are under threatened categories. In recent years, a chloroplast DNA-based molecular phylogenetic approach has been followed to understand the evolutionary relationship among the plant species. The interrelationship among the 14 Pandanus species at infrageneric level has been worked out using this approach, which has led to the rearrangement of some species to the subgenera proposed by Stone (1974). Moreover, the close relationship between Pandanus and Benstonea has been confirmed and the interrelationship of Indian Pandanus genus in global context is given. This book also describes the economic importance of each Pandanus species.

Book Description
Medicinal and aromatic crops (MACs) are high-value crops since the natural products obtained from them are low-volume high-value commodities that have numerous applications in various sectors such as the food, beverage, food supplement, flavor and fragrance, perfumery and cosmetics, pharmaceutical and aromatherapy industries. In addition, the plant biomass is used in the production of teas and medical applications in traditional and also modern medicines. MACs are important mainly because they contain plant secondary metabolites such as essential oils, alkaloids, glygosides, saponins, tannins, vitamins and other bioactives. Plant secondary metabolites are differentiated from plant primary metabolites of photosynthesis and respiration since they are directly involved in growth and development of plants. Some MACs are used as spices and culinary herbs since they contain mainly essential oils, and are used as tonic to the digestive system, appetite modification and other systems and may facilitate nutrient uptake and utilization from various foods. A significant amount of MACs and their natural products have also demonstrated antimicrobial, antifungal and bactericidal activity and significant antioxidant capacity. In the past, MACs and their natural products have been used as a source for various medicines, in food and beverage production and in aroma products. Essentials of Medicinal and Aromatic Crops summarizes the current knowledge on medicinal and aromatic crops, including the agronomical practices of important MACs and their products, their beneficial effects and utilization of MAP and their products. The chapters provide a comprehensive guide to the most important and used medicinal and aromatic crops and their use in functional foods, nutraceuticals and as bioactives against various ailments, providing researchers, teachers, chemists, food scientists, agronomists and agroecologists in academia, industry and government a fully up to date singular source on this important topic.

Book Description
When Rolf Dahlgren and I embarked on preparing this book series, Rolf took prime responsibility for monocotyledons, which had interested him for a long time. After finishing his comparative study and family classification of the mono cots, he devoted much energy to the acquisition and editing of family treatments for the present series. After his untimely death, Peter Goldblatt, who had worked with him, continued to handle further incoming monocot manuscripts until, in the early 1990s, his other obligations no longer allowed him to continue. At that time, some 30 manuscripts in various states of perfection had accumulated, which seemed to form a solid basis for a speedy completion of the FGVP monocots; with the exception of the grasses and orchids which would appear in separate volumes. I felt a strong obligation to do everything to help in publishing the manuscripts that had been put into our hands. I finally decided to take charge of them personally, although during my life as a botanist I had never seriously been interested in mono cots.

Book Description
The global environment has been going through significant challenges in recent times due to a number of factors such as industrial pollution, expansion of agricultural land way beyond the fringe forest zones, destruction of virgin forests, loss of quality agricultural lands due to soil erosion, loss of global wildlife and biodiversity, climate change, global warming, devastating forest fires, floods, draughts, melting of glaciers to mention only a handful. The list could possibly go on and on with never ending items being added covering every aspect of modern human life. But there is an important underlying hidden factor behind all these that we all need to identify and realize. The most alarming fact about this hidden factor is that they are all directly or indirectly impacted by human activities in some way or other. Human civilizations have reached great strides from the earliest days when men first discovered wheel or learnt the art of agriculture and crop and livestock breeding. We have seen the age of computronics, robotics and now moving into the age of biotechnology, genetic engineering and nanotechnology. Our science quests have stretched beyond the borders of the home planet and we have even started stretching hands in unlocking the secrets of distant members of our solar system. This is indeed tremendous progress; there could be no doubt about that. But at the same time we also need to remember about the impending darkness too beneath the lamp that provides light to the rest of room. While we are standing in gaining a lot; but are we paying enough attention to what we are also loosing at the same time. The loss of forested areas, building up carbon dioxide in the global atmosphere, pollution of both fresh and salt water via number of toxic chemicals both of inorganic and organic nature, poor quality of the air we are breathing and the catastrophic loss of global biodiversity- are these not a sign of regress instead of the so called and highly cherished progress towards a darker and destructive future. Human or anthropogenic impacts are in turn devastating the planet with our attention being shifted only to the shinning aspect of our civilizations. There is indeed a darker side of every bright picture that is being placed in front of our glaring eyes. There is no silver lining in every cloud that we see on the sky. We are becoming seriously myopic and choosing to ignore the deadly symptoms that are showing up in front of us every now and then as a result of our own activities. Anthropogenic impacts have been devastating to our global ecosystems and are challenging our local environments in a significant manner. As responsible global citizens we strongly believe that we need to voice our concerns to the incessant global environmental pollution happening at every instance at different corners of earth. Hence is the humble effort of coming up with an international, peer-reviewed volume on Anthropogenic Pollution: Causes and Concerns. The current volume is a collection of a number of articles from scientists, academics, researchers, journalists, bureaucrats and technocrats from different parts of the world. Each article talks about a separate story and highlights some specific problems caused by anthropogenic impact and resulting in detrimental forms of environmental pollution. Each article is complete with its table, graphs, diagrams and bibliography to cater to a wide range of readers from serious academics, researchers and students to environmental enthusiasts and general public interested in stretching their boundary of knowledge way beyond traditional education. The volume will also be useful for both under graduate and post graduate students specializing in environmental science/studies and also for the MPhil curriculum and entry level PhD courses at different academic institutes.
