Notes:

Definitions of codes preceding a county and/or quad:
*		Presumed extirpated
?		Uncertain about distribution or identity
?*		Uncertain about distribution, but presumed extirpated if once present
(?)		Occurrence confirmed, but possibly extirpated

Species may be present in other areas where conditions are favorable.

Quad data is not available for all List 3 and 4 plants. For those that do contain this data, it has not been quality controlled and is potentially incomplete, inaccurate, and/or out of date. Please use caution when referencing this information. We are currently working hard to maintain this data and hope to provide accurate and up to date information in the near future.
