NEW FEATURE! OAK LEAF IMAGES

I am most grateful to Jan De Langhe of Ghent University Botanical Garden, Belgium for contributing a large number of very high quality leaf image scans from living oaks in cultivation. These are from fresh material collected in the later half of the growing season. So far 137 images have been made available: it is hoped that this valuable work may be continued and extended next year and beyond. Click on a thumbnail appearing in a full name report and a high resolution version will load providing much diagnostic detail. For a list of names with leaf images to date, press here.

SEARCH FOR OAK SPECIES BY REGION

A new set of pages are now uploaded so that you can pick endemic oak species according to political regions. These pages operate as a separate section from the general search facility. This work will be further refined over time and other expert input is received. To access the Regional Search Page, press here.

IMPROVED LAYOUT AND LINKAGES

A navigation bar now appears on every page except for a search result report. Navigation throughout the site is easier, new windows are only opened for a full name report or to outside links. There are many more internal links to other data within a full name report (see below). The search page now has a link to a list of recent changes in the database that have a bearing on nomenclature. This will be automatically updated as any new changes are recorded.

NEW WORKS FULLY INCORPORATED

Hideaki Ohba's excellent account on oaks for the recent Flora of Japan (2006) has been fully incorporated into the database.

There are two major books featuring oaks due to be published in 2009. New Trees by John Grimshaw and Ross Bayton contains descriptions of 104 oak taxa, most of which have never been described before in a general dendrological work.  All references are now extracted into the database. Press here for further information on this important book.

Michael Heathcoat Amory's highly illustrated The Oaks of Chevithorne Barton with its 191 descriptions is also fully extracted and features under recent monographs. To learn more about this exciting new book, press here.

EXTRA REPORT FEATURES

A full name report now carries extra information under the following headings:

Infrageneric Classification Accepted species names are now assigned to a subgenus and/or section.

Common Names in this Database These are now listed alphabetically under a species name.

Infraspecific Taxa Accepted in this Database Where appropriate, subordinate taxa are listed under a species name.

Conservation Status Endangered species now carry the rating given to them in the Red List of Oaks.

Nomenclatural Type or other Herbarium Specimen For some taxa, illustrative specimens are made available for enlargement.

On-line Herbarium Specimen A start has been made in linking to nomenclatural types in virtual herbaria.

Oak Collections Growing this Taxon Important oak collections are now featured when they have living specimens of a taxon.
