Dansk flora kan benyttes til bestemmelse af alle karsporeplanter og frøplanter, der forekommer vildtvoksende eller tilsyneladende vildtvoksende i det danske landskab. Såvel nøgler som beskrivelser er udarbejdet helt fra grunden til denne bog, idet der er lagt stor vægt på klarheden i de enkelte nøgle-punkters valgmuligheder. Desuden bruges et moderne og forenklet botanisk fagsprog. Som noget nyt er mange slægter og bestemmelsestekniske detaljer illustreret, ofte med farveillustration af hele planter eller blomster. I familie-, slægts- og artsbeskrivelserne er de karakter-træk, der er af betydning for bestemmelsen endvidere fremhævet. Bogen er udarbejdet af 21 erfarne specialister og undervisere i danske planter og illustrationerne er udført på grundlag af levende materiale af de to tegnere, som begge har mange års erfaring i videnskabelig illustration.

Dansk feltflora er den mest omfattende danske flora og rummer en oversigt over den botaniske formlære, bestemmelsesnøgler til familier, slægter og arter samt et opdateret kort over botaniske distrikter.

This book invites the reader to take a unique journey through the history of the Solar System, the Earth, its evolving biodiversity and ecosystems, and the current state of the planet.It is an attempt to stimulate the reader’s sense of wonder and fascination with our planet: how it was created, the eons before it was populated by ourselves, how organic life, including humans, developed and evolved, and some of the threats we face during the Late Holocene.The Origins of All Things is well suited for teaching purposes, as it offers a synoptic, well-supported overview of key issues in biology and geology, and an easy introduction to key publications that broaden the scope of each chapter. The book is relevant for students of biology, geography, geology and anyone interested in the origin of life on Earth and its evolution.

Monocotyledons ('monocots'), though comprising only one fourth of all flowering plant species, are economically and ecologically crucial. In families such as the grasses and palms, they include some of the most valuable plant species to humanity. Numerous monocot species have great ornamental value due to their spectacular flowers or characteristic structural features. They range in size from the smallest flowering plants, Wolffia arrhiza, little more than 1 mm across, to massive palm trees up to 40 m tall. Monocot species occur in arctic regions, wet tropical forests, and deserts, and have a wide range of life forms, including floating and rooted aquatic plants, geophytes, epiphytes, and lianas.The book includes reviews and reports of current research by the world's leading specialists, based on presentations made at the Fourth International Conference on the Comparative Biology of the Monocotyledons and the Fifth International Symposium on Grass Systems and Evolution, held in Copenhagen in 2008.
