It occurs primarily in well drained sands and loamy sands of pine-oak sandhill communities, sand dunes and interdune hollows (Entisols), and pine flatwoods communities (Spodosols). It thrives in frequently burned areas (FSU herbarium). It is found in dry, scrub pinelands (Hall 1993).

Taxonomic notes

Description

It is an annual and flowers in the fall (Hall 1993). It flowers summer to fall (Wunderlin and Hansen 2003).

Distribution

It is infrequent in central, north, and west Florida. Found from: West to Mississippi, east to Alabama (Hall 1993).

Ecology

Habitat

It occurs primarily in well drained sands and loamy sands of pine-oak sandhill communities, sand dunes and interdune hollows (Entisols), and pine flatwoods communities (Spodosols). It thrives in frequently burned areas (FSU herbarium). It is found in dry, scrub pinelands (Hall 1993). It is found in dry pine-oak savannas, sandhills, and mesic bog margins (Wunderlin and Hansen 2003). Found in dry loamy sands, well drained sands, deep coarse sands, and loamy sand areas (FSU Herbarium). A. divaricata is also fund in human disturbed areas such as pine plantations, old fields, and along roadside edges and ditches. It does well in high levels of light (FSU Herbarium).

Associated species: Myrica, Pinus, Quercus, bunch grass association; Liatris and Pityopsis, Agalinis pulchella, A. aphylla, Quercus laevis, Aristida stricta, Andropogon spp.; Polygonella, Chrysopsis, Agalinis plukenetii, Haplopappus, Opuntia, Eupatorium, Agalinis tenuifolia, Quercus-Pinus Woods, Pinus-Serenoa, Dicerandra, Trichostema, Liatris gracilis, and others.

Phenology

Seed dispersal

Seed bank and germination

Fire ecology

It thrives in frequently burned areas; and occurs in areas with extremely xeric conditions (such as sand dunes) which limit competition with other vegetation (FSU herbarium).

Pollination

Use by animals

Diseases and parasites

Conservation and Management

A. divaricata requires fire or other vegetation-removing disturbance to maintain high light levels in the habitat which also reduces competition. It does not appear to be common in areas with a great deal of soil disturbance, although it occurs along roadsides and ditches (FSU herbarium).
