Description
A description of Eupatorium semiserratum is provided in The Flora of North America. Unlike other similar species, it often has 3 leaves per node that are whorled.[1]
Distribution
This species is distributed from southeast Virginia south to northeast Florida and the panhandle, west to Texas and Arkansas, and disjunct in Tennessee.[1]
Ecology
It has well-documented anticancer activities against various human cancer cell lines.[2]
Habitat
Generally, E. semiserratum can be found in savannas, swamp forests, seepage bogs, clay-based Carolina bays, and other various wetland habitats.[1] It has been observed in live oak hammocks, between floodplain swamps and powerline corridors, in depressions in flatwoods, longleaf pine-wiregrass savannas, pine flatwoods, scrub oak, banks of rivers, edges of cypress depressions, and in wet drainages on open wooded slopes. It is also found in human disturbed habitats such as roadside ditches and depressions, powerline corridors, and in areas that have been clear cut and plowed.[3]
Associated species include Pinus taeda, P. palutris, P. elliottii, Serenoa repens, Taxodium distichum, Liquidambar styraciflua, Eupatorium pilosum, E. semiserratum, E. recurvans, E. leucolepis, E. cuneifolium, E. mohrii, E. scabridum.[3]
Phenology
This species generally flowers from late July until October.[1] It has been observed flowering from August to October.[3][4]
