EUPATORIUM ALBUM L.

SIMILAR SPECIES: This plant can easily be confused with other white-flowered, sessile-leaved Eupatorium species, especially E. rotundifolium, E. sessilifolium, and E. altissimum. It also could be confused with Kuhnia eupatorioides. These species are distinguished by a combination of leaf and floral characters. TOTAL RANGE: Coastal states from s. CT to c. FL and w. to MS, also inland in the mountainous regions to s. OH and e. KY and TN, and in AR. STATE RANGE (as of 2008): Post-1980 records are from Jackson, Pike, and Scioto counties.

RECOVERY POTENTIAL: Presumed good due to its generalized habitat and tolerance of disturbance. INVENTORY GUIDELINES: Mature flowering material is needed for identification. COMMENTS: This species displays extreme morphological variability throughout its range. There are diploid and triploid races and the diploids hybridize (outsid
