NatureServe Global Conservation Status Factors

Range Extent Comments: Southern Arkansas, northern Louisiana, and eastern Texas (Cronquist 1980). Browne and Athey (1992) report Eupatorium lancifolium in extreme western Kentucky (Calloway County). Kartesz (unpublished data 1995) includes Alabama but does not include a state record for Arkansas. Status in Arkansas uncertain because Smith (1988) does not consider it distinct from Eupatorium cuneifolium Willd. var. semiserratum (DC.) Fern. & Grisc. (=Eupatorium semiserratum DC.); mapped from one parish in extreme southwestern Louisiana (MacRoberts 1989b) but also reported from central part of the state (Gandhi & Thomas 1989).
