How to Use this Key -

This web page is intended to teach you how to use a plant key. To use this key:

  1. Read the two descriptions for selection in each key couplet.
  2. In each couplet, there are two numbers on the right side of the screen. Click on the number on the right side of the screen to select the description that matches your plant.
  3. The option that you select will take you through a series of couplets until you reach the identity of your plant.

Highlighted words are linked to a glossary and can be clicked to see a definition. For more detailed information, see the "How to Use this Key" tutorial.
