Taxonomic notes

Synonyms: E. hieracifolia var. hieracifolia; E. hieracifolia var. intermedia Fernald; E. hieracifolia var. praealta (Rafinesque) Fernald; Senecio hieraciifolius Linnaeus.[1]

Varieties: none.[1]

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." [2]

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.[3] It has also been introduced to Hawaii.[4]

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.[3] 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.[5] It has been observed to be an early-successional species, becoming abundant early after disturbance but decreasing in abundance as the years since a disturbance increase.[6] Though it can be found in shady areas, E. hieracifolia requires high light for establishment.[7] E. hieracifolia responds positively to agricultural-based soil disturbance in South Carolina coastal plain communities marking it as a possible indicator species for post-agricultural woodland.[8] It also responds positively to soil disturbance by clearcutting and chopping in North Florida flatwoods forests.[9]

Associated species include Pluchea sp., Kostelezkya sp., Liatris sp., Panicum sp., Leptoloma cognatum, Ambrosia sp., Conyza canadensis, Mikania scandens, Lygodium japonicum, and other grasses.[5]

Erechtites hieracifolia is an indicator species for the Calcareous Savannas community type as described in Carr et al. (2010).[10]

Phenology

Generally, this species flowers from late July until November.[3] 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.[11][5]

Seed dispersal

This species is thought to be dispersed by wind. [12]

Seed bank and germination

E. hieracifolia was found in the seed banks of bays dominated by herbaceous and shrub plants in western South Carolina.[13] 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.[14] Seeds were also one of the highest importance values in a Virginia pocosin for early succession.[15] As well, this species has a positive germination response to fire disturbance.[16] Almost all seeds in a study by Mou germinated pre-scarification, and almost all germinated in an early-successional time period.[17]

Fire ecology

It has been observed in areas that are frequently burned and annually burned.[5] One study in New Hampshire found this species to germinate in response to fire.[16] Cool burns as well as litter removal have been shown to improve germination success, which could mean that removing litter is a process that favors colonization.[18] E. hieracifolia has been seen to immediately increase in response to fire since it is opportunistic, but decrease in abundance in the years following a fire disturbance to its original abundance before fire was introduced.[19][20] It can also tolerate fire whether or not the herbicide imazapyr is applied to the plant.[21] A study on fire seasonality only found E. hieracifolia to benefit from winter burns.[22] As well, overall biomass of this species was found to hit its peak eight months after a fire disturbance.[23]

Pollination

The following Hymenoptera families and species were observed visiting flowers of Erechtites hieracifolia at Archbold Biological Station. [24]

Halictidae: Halictus poeyi

Leucospididae: Leucospis affinis

Megachilidae: Dianthidium floridiense

Vespidae: Leptochilus republicanus, Parancistrocerus bicornis, P. salcularis rufulus, Polistes dorsalis hunteri

Other species in the Hymenoptera order observed to pollinate E. hieracifolia include Anthidiellum perplexum and Megachile albitarsis.[25]

Use by animals

It consists of approximately 2-5% of the diet for various terrestrial birds.[26]

Conservation, cultivation, and restoration

For management, this species is resistant to the herbicide imazapyr.[21] It is also quite resistant to the herbicide imazapyr-glyphosate.[27]
