Taxonomic notes
Synonym: Erechtites hieracifolia var. hieracifoliaThe Plant List.org; E. hieracifolia var. intermedia Fernald; E. hieracifolia var. praealta (Rafinesque) Fernald; E. hieracifolia; Senecio hieraciifolius Linnaeus
Description
"Robust annual with erect, glabrous or slightly pubescent, solid stems, 0.4-3 m or more tall. Leaves alternate, elliptic to lanceolate, 5-20 cm long, 0.5-6.5 cm wide, acute to acuminate, irregularly serrate to dentate, unlobed or lobed, base cuneate to attenuate or upper stem leaves auriculate. Heads in panicles. Involucres cylindric, 10-20 mm long, 4-8 mm broad; bracts in 1 series or with a few small bracts at base. Disc 3-10 mm broad. Flowers discoid, lobes cream to pinkish, erect, 0.3-0.5 mm long. Nutlets brown, tapered from base to apex, 1.9-2.7 mm long, 0.4-0.7 mm broad, 10-ribbed, pubescent; pappus white, capillary, 10-14 mm long." [1]
Distribution
This species can be found from Canada southward, from Newfoundland west to Saskatchewan provinces south to southern Florida and eastern Texas. It is also native south of the United States including the West Indies and Tropical America.[2] It has also been introduced to Hawaii.[3]
Ecology
Habitat
Can be found in almost all habitats in disturbed soil besides extremely xeric soils. It is present in most areas of modern beat-up landscapes (even if just seedlings) and appears at the smallest disturbance. With this, it is most prevalent in areas that are heavily disturbed or scarified by timber-harvest, bulldozing, and severe fire disturbance.[2] Habitats that E. hieracifolia has been observed in include edge of drying mudhole, margin of pine flatwoods, hydric hammock, areas disturbed by feral hogs, spoil flats, swamps, sandhills, sandy fields and various clearings, boggy margins, a riparian mixed hardwood community, other woodlands, and a run off area. Soils observed include drying loamy sand, moist sand and other sandy soils, and sandy peat.[4]
Associated species include Pluchea sp., Kostelezkya sp., Liatris sp., Panicum sp., Leptoloma cognatum, Ambrosia sp., Conyza canadensis, Mikania scandens, Lygodium japonicum, and other grasses.[4]
Phenology
Generally, this species flowers from late July until November.[2] E. hieracifolia has been obseved flowering in all months besides February and May, and has been observed fruiting in March, April, and June through October.[5][4]
Seed dispersal
This species is thought to be dispersed by wind. [6]
Seed bank and germination
E. hieracifolia was found in the seed banks of bays dominated by herbaceous and shrub plants in western South Carolina.[7] Another study found this species to germinate from the seed bank of a restoration site in southwest Georgia even when the species was not part of the herbaceous vegetation.[8] Seeds were also one of the highest importance values in a Virginia pocosin for early succession.[9]
Fire ecology
It has been observed in areas that are frequently burned and annually burned.[4] One study in New Hampshire found this species to germinate in response to fire.[10]
Pollination
The following Hymenoptera families and species were observed visiting flowers of Erechtites hieracifolia at Archbold Biological Station. [11]
Halictidae: Halictus poeyi
Leucospididae: Leucospis affinis
Megachilidae: Dianthidium floridiense
Vespidae: Leptochilus republicanus, Parancistrocerus bicornis, P. salcularis rufulus, Polistes dorsalis hunteri
Use by animals
It consists of approximately 2-5% of the diet for various terrestrial birds.[12]
