Book Description
"The Atlas of Illustrations, published as the second volume of The New Cactus Lexicon in 2006, set out to be the most comprehensive collection of images of these species yet published in book form, and remains a useful reference for those interested in the diversity of the cactus family or wishing to confirm or determine the identity of individual specimens. To satisfy continuing demand for copies, this edition is the response. It is basically a reprint with corrections of the original volume, but the pagesize has been reduced to economize on production costs and to achieve a substantial reduction in the cover price. The opportunity of a reprint also enables us to point out where recent research indicates or suggests improvements to the classification that can or could be made and to make minor rearrangements without upsetting the overall scheme (see the following pages). In the past two decades hypotheses concerning the phylogeny and evolution of the principal groups of cacti have been greatly encouraged and assisted by studies at the molecular level, enabling us to be more confident of relationships previously interpreted largely on the basis of morphological similarities and differences, and in a few cases to realise that we have been deceived by similarities that can now be attributed to evolutionary convergence. But whilst molecular evidence, summarized in the cladogram or phylogram that is now the sine qua non of a respectable taxonomic paper, may reliably indicate groups related or not related by common ancestry, it does not dictate the rank (genus or subgenus etc) at which the groups should be recognized--or tell us in practical terms how they are to be distinguished! So there is still plenty of scope for differing opinions, and general agreement or consensus on an updated list of genera to be recognized/not recognized seems a distant prospect. To date only a relatively small proportion of the family has received in depth analysis, and the results mostly await independent confirmation. The plants themselves, however, are unchanging, whatever we choose to call them, and the photographic record we have of them is factual and permanent, like preserved specimens in a scrapbook or herbarium (which some might regard as kind of a glorified scrapbook!) and sometimes, for cacti at least, more informative."--Preface.

Book Description
This volume - the first of this series dealing with angiosperms - comprises the treatments of 73 families, representing three major blocks of the dicotyledons: magnoliids, centrosperms, and hamamelids. These blocks are generally recognized as subclasses in modern textbooks and works of reference. We consider them a convenient means for structuring the hundreds of di cotyledon families, but are far from taking them at face value for biological, let alone mono phyletic entities. Angiosperm taxa above the rank of family are little consolidated, as is easily seen when comparing various modern classifications. Genera and families, in contrast, are comparatively stable units -and they are important in practical terms. The genus is the taxon most frequently recognized as a distinct entity even by the layman, and generic names provide the key to all in formation available about plants. The family is, as a rule, homogeneous enough to conve niently summarize biological information, yet comprehensive enough to avoid excessive re dundance. The emphasis in this series is, therefore, primarily on families and genera.

Book Description
Cacti are full of contradictions. Although many are found in the driest and most barren environments on earth, some grow exclusively in the branches of the rainforest canopy. Many species bristle with ferocious-looking spines, while other varieties are perfectly smooth. And while they might strike us as the most austere plants on earth, nearly all of them exhibit remarkable floral displays—some even larger than the plant itself. In Cactus, Dan Torre explores these unique plants as they appear all around the world and throughout art, literature, and popular culture. As Torre shows, cacti have played a prominent role in human history for thousands of years. Some species were revered by ancient civilizations, playing a part in their religious ceremonies; other varieties have been cultivated for their medicinal properties and even as a source of dye, as in the case of the prickly pear cactus and the cochineal insect, the source of red carmine used in everything from food to lipstick. Torre examines how cacti have figured in low-footprint gardens, as iconic features of the landscapes of Westerns, and as a delicious culinary ingredient, from nutritious Nopal pads to alluring Pitaya—or Dragon—fruits. Entertaining and informative, this book will appeal to any of us who have admired these hardy, efficient plants.

Book Description
The European Garden Flora is the definitive manual for the accurate identification of cultivated ornamental flowering plants. Designed to meet the highest scientific standards, the vocabulary has nevertheless been kept as uncomplicated as possible so that the work is fully accessible to the informed gardener as well as to the professional botanist. This new edition has been thoroughly reorganised and revised, bringing it into line with modern taxonomic knowledge. Although European in name, the Flora covers plants cultivated in most areas of the United States and Canada as well as in non-tropical parts of Asia and Australasia. Volume 2 contains accounts of the first 71 families of Dicotyledons, including the Aizoaceae and Cactaceae (large and important families of succulents), as well as many tree families (Juglandaceae, Betulaceae, Fagaceae, Ulmaceae) and popular herbaceous plants (Ranunculaceae, Papaveraceae, Cruciferae).
