You choose which of these options matches your specimen, then follow the path to either the next set of questions or the end result. If they were not palm-shaped, or in some other way didn’t match the description, you would choose 6b and proceed to the set of questions labeled 7a and 7b to make your next choice.

You will be using this key to identify your own two unknowns. Based on your dichotomous key, list the metabolic tests you will need to identify each of your unknowns, and the media that you will used for each test. Unknown A: Metabolic test required Unknown A: Media Unknown B: Metabolic test required Unknown B: Media

Number is attached to the first choice whereas the second choice is marked with minus “–”. The choice will lead either to the name, or to another step. The choice sentence might contain several phrases, the first is the most important and the last is the least important.
