Natural range of Agalinis divaricata from USDA NRCS Plants Database.

Common names: Pineland False Foxglove; Little Gerardia


Taxonomic notes

Synonyms: Gerardia divaricata Chapm.

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<ref name="fsu".Florida State University Robert K. Godfrey Herbarium database. URL: http://herbarium.bio.fsu.edu. Last accessed: June 2014. Collectors: Sidney McDaniel, Andre F. Clewell, Robert K. Godfrey, Paul O. Schallert, J. M. Canne, John Morrill, Loran C. Anderson, J. Hays, Robert Kral, Jean W. Wooten, H. E. Grelen, John C.

States and Counties: Florida: Bay, Calhoun, Franklin, Gadsden, Gulf, Jackson, Leon, Liberty, Levy, Okaloosa, Santa Rosa, Wakulla, Walton, and Washington.</ref>. 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[1]. 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.

Associated species: Myrica, Pinus, Quercus, Liatris, Pityopsis, Agalinis pulchella, Agalinis aphylla, Agalinis tenuifolia, Agalinis plukenetii, Quercus laevis, Aristida stricta, Andropogon spp.; Polygonella, Chrysopsis, Haplopappus, Opuntia, Eupatorium, Dicerandra, Trichostema, Liatris gracilis, and others[2].


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).

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).
