Genus Sorbus

mountain ash and other rowans

Hugh McAllister

Royal Botanic Gardens, Kew, 2005

Varying from tiny mountain shrubs to tall trees, there is a rowan suitable for every garden. Dr McAllister has 25 years of knowledge and experience in growing rowans, and in this book describes over 60 visually striking species, including recent introductions from China. The re-appraisal of classification, evolutionary history, ecology and conservation will bring botanists up to date on latest research, while sections on propagation and cultivation will prove invaluable to gardeners, nurserymen and horticulturists. Eighteen full-page paintings by the renowned artist Josephine Hague, and over 100 colour photographs, illustrate the text.

The Genus Betula

A Taxonomic Revision of Birches

Kenneth Ashburner and Hugh McAllister

Royal Botanic Gardens, Kew, 2013

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 The authors present previously unpublished data on recent molecular work and fossils, providing a cytotaxonomic and phylogeographic revision of the Betula genus.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.
