On Drepanophycus Protolepidodendron And Protopteridium With Notes On The Palaeozoic Flora Of Yunnan

A modern approach to understanding the evolution and diversification of land plants, one of the most exciting areas of plant systematics. It consists of three sections - origin and diversification of primitive land plants; origin and diversification of angiosperms; speciation and mechanisms of diversification - each section corresponding to a major area in plant evolution. In each case, data from molecular, morphological, and paleontological approaches are presented, backed by recent progress and new findings, together with proposals for future research. A guide to the latest in plant systematics, heightening awareness of prospective future problems.

A compilation of state of the art papers on key topics in bryology from invited speakers at the Centenary Symposium, University of Glasgow, 57 August 1996.

What do we now know about the origins of plants on land, from an evolutionary and an environmental perspective? The essays in this collection present a synthesis of our present state of knowledge, integrating current information in paleobotany with physical, chemical, and geological data.

New Organic Architecture is a manifesto for building in a way that is both aesthetically pleasing and kinder to the environment. It illuminates key themes of organic architects, their sources of inspiration, the roots and concepts behind the style, and the environmental challenges to be met. The organic approach to architecture has an illustrious history, from Celtic design, Art Nouveau, Arts and Crafts, to the work of Antoni Gaud� and Frank Lloyd Wright. Today there is a response to a new age of information and ecology; architects are seeking to change the relationship between buildings and the natural environment. In the first part of his book, David Pearson provides a history and assessment of organic architecture. The second part comprises statements from thirty architects from around the world whose work is based on natural or curvilinear forms rather than the straight-line geometrics of modernism. Each statement is accompanied by full-color illustrations of one or several of the architects' built projects.
