This volume is the outcome of a modern phylogenetic analysis of the grass family based on multiple sources of data, in particular molecular systematic studies resulting from a concerted effort by researchers worldwide, including the author. In the classification given here grasses are subdivided into 12 subfamilies with 29 tribes and over 700 genera. The keys and descriptions for the taxa above the rank of genus are hierarchical, i.e. they concentrate upon characters which are deemed to be synapomorphic for the lineages and may be applicable only to their early-diverging taxa.
Beyond the treatment of phylogeny and formal taxonomy, the author presents a wide range of information on topics such as the structural characters of grasses, their related functional aspects and particularly corresponding findings from the field of developmental genetics with inclusion of genes and gene products instrumental in the shaping of morphological traits (in which this volume appears unique within this book series); further topics addressed include the contentious time of origin of the family, the emigration of the originally shade-loving grasses out of the forest to form vast grasslands accompanied by the switch of many members to C4 photosynthesis, the impact of herbivores on the silica cycle housed in the grass phytoliths, the reproductive biology of grasses, the domestication of major cereal crops and the affinities of grasses within the newly circumscribed order Poales.
This volume provides a comprehensive overview of existing knowledge on the Poaceae (Gramineae), with major implications in terms of key scientific challenges awaiting future research. It certainly will be of interest both for the grass specialist and also the generalist seeking state-of-the-art information on the diversity of grasses, the most ecologically and economically important of the families of flowering plants.
This concise guide shows novice houseplant owners exactly how to keep indoor plants alive and healthy. Gardening expert Ellen Zachos helps you choose the right plants in the first place and then shows you how to care for them, outlining what each kind needs in terms of location, sunlight, water, and fertilizer. She also explains when plants should be repotted (and how to do that successfully), how and when to prune them, how to keep them clean of dust and pets, and more. This Storey BasicsÂ® guide has all the information you need to keep any houseplant thriving and beautiful!
[SCENE.--A room furnished comfortably and tastefully, but not extravagantly. At the back, a door to the right leads to the entrance-hall, another to the left leads to Helmer's study. Between the doors stands a piano. In the middle of the left-hand wall is a door, and beyond it a window. Near the window are a round table, arm-chairs and a small sofa. In the right-hand wall, at the farther end, another door; and on the same side, nearer the footlights, a stove, two easy chairs and a rocking-chair; between the stove and the door, a small table. Engravings on the walls; a cabinet with china and other small objects; a small book-case with well-bound books. The floors are carpeted, and a fire burns in the stove.
This book presents up-to-date information on a total of 75 native and non-native medicinal plants growing in Singapore. Comprehensive and useful information from the published literature - including plant descriptions and origins, traditional medicinal uses, phytoconstituents, pharmacological activities, adverse reactions, toxicities, and reported drug-herb interactions - is presented in an easy-to-read manner for easy and quick reference. There is no minimum level of knowledge required to read this book, and botanical and medical glossaries are also provided for readers' convenience.The book will be of great practical benefit to a wide-ranging audience. Educators and students in complementary medicine and health, pharmacognosy, medicinal chemistry, natural products, pharmacology, toxicology, pharmacovigilance, medicine, pharmacy, nursing, botany, biology, chemistry and life sciences will find the information useful. The book will also appeal to clinicians, pharmacists, nurses and researchers, as it contains a comprehensive reference list at the end for further reading.
