103. Elephantopus L. (elephant’s foot)

(Clonts, 1972; Clonts and McDaniel, 1978)

About 30 species, nearly worldwide, except Europe and northern Asia.

In addition to the single species recorded thus far from Missouri, two additional taxa of the southeastern United States have been collected in adjacent counties of Arkansas. Both differ from E. carolinianus in having the leaves mostly basal and stem leaves much smaller than the basal ones. Elephantopus nudatus A. Gray has slightly smaller heads and achenes, and the pappus bristles are flattened and broadened to a triangular base. Elephantopus tomentosus L. has relatively large heads and achenes and has usually woolly pubescence on the involucral bracts (and sometimes also the leaf undersurface). These species might possibly be discovered in the southernmost tier of Missouri counties in the future.
