Contents
Taxonomic notes
Synonym: Gerardia divaricata Chapm.[1]
Description
It is an annual and flowers in the summer and fall.[2][3]
Distribution
Agalinus divartica is infrequent in central, north, and west Florida, but is endemic to Mississippi, Alabama, and Florida[2]. It is listed as critically imperiled in Alabama and Georgia.[4]
On the Florida panhandle and northern peninsula, observations have been made from Santa Rosa county[5][6], eastward to Leon and Wakulla, and in Levy, Alachua, Marion, Citrus, and Hernando counties.[5]
Ecology
Habitat
A. divaricata occurs primarily in well drained and loamy sands such as pine-oak sandhill communities, sand dunes, interdune hollows (Entisols), and pine flatwoods communities (Spodosols). It thrives in frequently burned areas,[7] and in human disturbed areas such as pine plantations, old fields, along roadside edges and ditches where there are high levels of light.[7]
Agalinis divaricata is an indicator species for the Panhandle Silty Longleaf Woodlands community type as described in Carr et al. (2010).[8]
Associated species include Morella cerifera, Agalinis pulchella, Agalinis aphylla, Agalinis tenuifolia, Agalinis plukenetii, Quercus laevis, Aristida stricta, Liatris gracilis, and others.[7]
Phenology
Agalinis divaricata has been observed to flower between September to December with the peak of inflorescence in October.[9][5]
Fire ecology
It thrives in frequently burned areas.[7]
Herbivory and toxicology
Like other Agalinis species, A. divaricata hosts larvae of the common buckeye butterfly (Junonia coenia) in Florida.[5]
Conservation, cultivation, and restoration
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.[7] This species is highly threatened by land-use conversion, habitat fragmentation and forest management practices.[4]
