	Extended Character Key This form is best used when you don't have a complete specimen of the grass you are trying to identify, or when there is something obvious about it that is not a search field on the Illustrated Key. The same search suggestions apply: Do not guess! Do not attempt to fill in all the boxes. Start with a few obvious characteristics. For measurements, an average of several specimens is best. For interpretation of the individual features see the help files.
