The website for the Global Compendium of Weeds has been updated with a new, improved search interface. For those of you not familiar with it, the GCW website, a joint effort of the USGS and the Western Australia Dept. of Agriculture, provides nomenclature, place of origin, and references documenting the weediness of hundreds of plant species. The online database is only a partial listing of the 20,000 species that will be included in the book version. It is unclear as to whether the website will be updated to include the complete species listing.
(Thanks to a member of the ALIENS-L listserver for posting info about the GCW website.)
