Notes Glossary
  • Occurrences are few and possibly local, but widely distributed; needs field surveys. Difficult to differentiate from E. tomentellus and E. vialis; needs further study. See Pittonia 2(7B): 17 (1889) for original description, and Pittonia 3(14B): 56 for revised nomenclature (1896).

  • 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. This data should NOT be substituted for pre-project review or for on-site surveys.
Includes unprocessed quads for CRPR 3 and 4 plants; unprocessed location data has not been quality controlled and may contain errors.
