Taxonomic notes

Description

A description of Erigeron quercifolius is provided in The Flora of North America.

E. quercifolius can be a winter annual, biennial or short live perennial, depending on environmental conditions. Basal leaves have a deeply notched margin, with yellow-green leaves that are rough to the touch. Flower stalks emerge from the center of the basal rosette and can reach about 12-24 inches tall by early summer. The flower heads are small and are composed of many thin, ray betals surrounding a rounded yellow disc [1]. Flowers can be blue, white or pink[2].

Distribution

Ecology

Habitat

E. quercifolius can be found in wetland depressions, wet pinelands, dry turkey-oak pinelands, pine flatwoods, moist open hammocks, and peaty soils of cypress-gum swamps. It is a quick to colonize openings and disturbed areas such as roadsides, vacant lots, open fields, and drainage ditches. Soils include loamy sand, peaty soil, and shell rock [3](FSU Herbarium). Associated species include Helenium pinnatifidum, Parietaria praetermissa, Micromeria brownei, Spermacoce assurgens, Galium hispidulum, Vicia floridana, Commelina diffusa, Rumex verticillatus, Galium tinctorium, Boehmeria cylindrica, and Saururus cernuus (FSU Herbarium).

Phenology

It has an inferior ovary[4] and flowers March through October (FSU Herbarium). Fruits are achenes[4].
