Between 2002 and 2004, 1392 Cyperaceae specimens were examined and the information repatriated. This checklist records 191 species in 24 genera, with entries listed alphabetically and sorted by state, collector and number.

The stunning Betula, or birch trees, are notoriously difficult to identify despite being one of the major contributors to the beautiful fall foliage famous in eastern North America. With many wrongly named birches appearing in nurseries and arboreta, this new book, the first ever written on the genus, is an important and much-needed work.

The Genus Betula covers all known birches found in North America, Europe, and Asia, along with keys for accurate identification. Chapters include a look at the breeding, cultivation, conservation, and morphology of all species, including several little-known species wonderful for garden and landscape use. The authors present previously unpublished data on recent molecular work and fossils, providing a cytotaxonomic and phylogeographic revision of the Betula genus. The book is accompanied by exquisite specimens of botanical art, including full-color paintings by Josephine Hague, making it a valuable tool for arboriculturists as well as professional and amateur gardeners.

Thousands of years ago, Asia was filled with forests that connected ecosystems from the foot of the Himalayas to the shores of the Pacific. Today, more than half of these woodlands are gone, mostly due to the demands of commerce and industry. And while conservation efforts are underway, more parcels disappear every year. On the Forests of Tropical Asia is a timely record of current forests and a much-needed explanation of the role humans played in the devastation and redevelopment of these forests.
On the Forests of Tropical Asia is the first book to describe the forests of the entire tropical Asian region, from Sind to New Guinea. It opens with chapters on physical geography and geological history and then moves on to address forest and tree structure and dynamics, floristics, and symbiotic organisms, as well as genetics, evolutionary history, species diversity, and human impact. A final chapter covers future policy and practice options for saving what remains. Hundreds of full-color illustrations serve as a lasting testimony to the diverse forests. Ashton combines existing research with his own experience and collaborations, creating a broad, comprehensive understanding of forest variation. By presenting a clear picture of where the forests stand today, he offers a framework for future research, policy, and conservation.
