In the Federal Noxious Weed Disseminules of the U.S. tool you will find three interactive family keys, fact sheets, descriptions and images to aid in the identification of disseminules produced by taxa on the federal noxious weed list. The interactive keys are Lucid3 Java Applets. Lucid3 is software for creating and using interactive identification keys. Lucid was developed by the Centre for Biological Information Technology at the University of Queensland in Australia. Visit the Lucidcentral web site for more information on Lucid and Lucid3.
Lucid3 system requirements —
Operating System: Windows 98/ME/NT/2000/XP/2003/Vista, Mac OSX, Linux, Solaris.
System Memory: 128MB RAM (256MB or greater recommended).
Web browser: Java-enabled web browser such as Internet Explorer, Firefox, Opera, or Safari.
NOTE: Some web pages, such as fact sheets attached to items in Lucid3 interactive keys, may be considered pop-ups by certain web browsers. If your browser or an add-on application is set to block pop-ups, you may not be able to view all of the content on these pages. Additionally, some web browsers or add-on applications may block "active content" on web pages or interactive keys. To take full advantage of the information presented in this Lucid tool, please consult your web browser or add-on application's help file for assistance in disabling pop-up blockers and allowing active content.
Software: The Lucid3 interactive key will run embedded within a web browser as a Java applet Player. Java Runtime Environment (JRE) version 1.4.2 (1.5 or greater recommended) must be installed on your computer for the Lucid3 Applet Player to run successfully.
You can download and install the latest JRE version from the Java web site at www.java.com.
Some Java versions greater than 1.5 may have bugs that affect operation of the interactive key. This can usually be cured by downloading the latest JRE version from the Java web site.
Note to Macintosh users: OSX comes pre-installed with the JRE and is accessible using Safari. Ensure you have the latest version of JRE by running the software update utility. Internet Explorer version 5.2.3, which is the latest version of IE for the Mac, does not support JRE, nor does Opera. If you use Firefox, Mozilla, or Camino as your browser, there is a Java Embedding Plugin that will enable them to access JRE and run the Key. See the links below for information regarding installation, compatibility and updates for the plugin. The Java Embedding Plugin does not work with Explorer or Opera.
