Choose one of the links above for a list of plant-related websites about that category. Selected websites include only non-commercial, free-access sites that do not require passwords. The links provided have all been checked as of April 18, 2008, but visitors should note that most large websites have a regular downtime for editing and uploading more information. Often, this downtime occurs on the weekends, especially Sunday night (students take note!). If you find a link that doesn't work, try that site again at a different time or on a different day; if it still does not work, please report the problematic link to the NOPD.Graminoids (grasses, sedges, and rushes)
