Description
A description of Eupatorium mohrii is provided in The Flora of North America.
Distribution
This species is distributed from southeast Virginia south to southern Florida and west to Texas.[1]
Ecology
Habitat
Generally, E. mohrii can be found in moist savannas as well as other wet habitats.[1] Native, perennial herb in longleaf pine stands.[2] It does well in open canopy areas on longleaf pine habitats. Does not do well in highly disturbed areas (such as clear cutting).[3] It is found areas that have become wet in some parts of the year such as in slash pine flatwoods, hammocks, near creeks, pond-pine scrubs, peaty pine savannas, wet flatwoods, swampy depressions between sand ridges, pine-palmetto flatwoods, upper edges of hillside bogs, edges of titi bogs, swales and dunes, and in river floodplains. It is also found in human disturbed areas such as pinelands that have been clear cut, along roadside depressions, embankments, edges of an artificial pond, and in powerline corridors. It is associated with areas that have moist soil, moist sandy peaty soil, semi-wet soil, muckly aulluvium soils, and moist sandy clay.[4]
Associated species include Eupatorium rotundifolium, E. album, E. cuneifolium, E. leucolepis, E. recurvans, E. mikaniodes, Andropogon, Aster dumosus, Ludwigia virgata, Carex joorii, Panicum rigidulum, Rhexia mariana, Rubus cuneifolius, Magnolia virginina, Pinus palutris, P. elliottii, P. taeda, Serenoa repens, Aristida stricta, Quercus, Liquidambar styraciflua, Cyrilla racemiflora.[4]
Eupatorium mohrii is an indicator species for the Peninsula Savannas community type as described in Carr et al. (2010).[5]
Phenology
E. mohrii generally flowers from August until October.[1] It has been observed flowering from June to November.[6][4]
Seed bank and germination
Seeds of Eupatorium mohrii were found to persist in the seed bank after a fire disturbance. It is normally found in the seed bank, but is not as prevalent as other species.[7]
Fire ecology
This species commonly occurs in pinelands that are fire-dependent.[8] The seeds of this species have also been found to persist in the seed bank even after a fire disturbance.[7]
Pollination
Eupatorium mohrii has been observed at the Archbold Biological Station to host wasps such as Pachodynerus erynnis (family Vespidae), thread-waisted wasps from the family Sphecidae such as Bicyrtes capnoptera, B. insidiatrix, Cerceris blakei, Philanthus ventilabris, Prionyx thomae, Tachytes pepticus, and T. validus, leafcutting bees from the family Megachilidae such as Coelioxys mexicana, Dianthidium floridiense and Megachile albitarsis, wasps from the family Leucospididae such as Leucospis robertsoni, and L. slossonae, sweat bees from the family Halictidae Agapostemon splendens and Halictus poeyi, and bees from the family Apidae such as Apis mellifera, and Bombus impatiens.[9] Other pollinators in the Hymenoptera order include Halictus ligatus.[10] E. mohrii also attracts various butterflies as a nectar source for pollination.[11] Thick-headed flies in the genus Physoconops were collected from the flowers of E. mohrii and possibly pollinate the plant as well.[12]
