NEW FEATURES IN THE ON-LINE CHECKLIST FOR 2009-2010
The data on distribution first presented on this website last September has undergone much revision over the past winter months with much extra data incorporated, together with an improved layout that lists countries by geographical regions. Press here to see the latest data which is now open for peer review.
Data from the English edition of this important work, originally published in Russian, are now fully incorporated into the database. For further details of this work, press here: you will find purchasing details and a list of taxa featured in this work.
The new (8th Edition) of the International Code of Nomenclature for Cultivated Plants was published just before Christmas. The provisions of this new Code will be incorporated within the Checklist over the coming months. For further details of the Code, press here.
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 generally from fresh material collected in the later half of the growing season. Over 141 images were made available in 2009 with a further 273 during 2010. 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 all names with leaf images, press here, or, for a list of the newer images for 2011, press here.
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.
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.
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.
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.
