Please note that there are five different ways to view this key, which you can find by clicking on the dropdown menu in the top left. Through that menu there are several other buttons leading to information, which we encourage you to check out.
You can hover over the species names to view photos of them, and click on the names of the distinguishing features to see comparative images (only in Two Column Key).
You do NOT need to input all of the characters, just what you can see.
Please contact the author through iNaturalist or by email if you have any questions or find an issue with the key.
Note for this key: If you are left with the two options of P. texana and P. marginata, you may leave the record at the P. marginata complex.
