Taxonomic notes
Synonym: Gerardia filifolia Nutt.
Description
It is an annual.[1]
Distribution
This species is frequent in all of Florida, to which it is almost endemic.[2] However, its range barely extends into parts of Georgia and Alabama.[1] In Georgia it is listed as critically imperiled.[3]
Ecology
Habitat
This species is found in sandhills and coastal scrub.[4] It is also found in longleaf pine savannas, sandy pinewoods and barrens, and on sand dunes, flats, and interdune hollows. Other habitats includes open stands of evergreen oak shrub, flatwoods, saw-palmetto woods, borders of titi bogs, in dry sandy scrub that borders mesic woodlands,[5] scrubby flatwoods, and on roads or firebreaks.[2] Agalinis filifolia is somewhat shade tolerant and found in a variety of moisture conditions, from dry to wet.[1] It is observed in mainly sandy soils, including loamy sand. It can also be found in disturbed habitats, including clear-cuts and pine plantations, roadside banks and ditches, and clearings for power lines.[5]
Associated species include Myrica cerifera, Aristida stricta, Myrica pusilo, Aristida spiciformis, Chrysoma, Polygonella, Ceratiola, Conradina, Saw palmetto, Quercus species, and Pinus species.[5] Polygonella associates may include P. polygama var. polygama or P. brachystachya, pending final taxanomic identification.[2]
Phenology
This species has been observed flowering August through October, and fruiting August through November.[5] In central Florida, A. filifolia may be one of the earliest Agalinis species to peak flowering.[2]
Pollination
Polites vibex (the whirlabout or skipper) is known for nectaring A. filifolia.[6] Additionally, the following Hymenoptera families and species were observed visiting flowers of Agalinis filifolia at Archbold Biological Station:[7]
Apidae: Apis mellifera, Bombus impatiens, B. pennsylvanicus
Halictidae: Agapostemon spledens, Augochlorella aurata, A. gratiosa, Lasioglossum coreopsis, L. miniatulus, L. nymphalis, L. placidensis, L. puteulanum
Megachilidae: Megachile brevis psedudobrevis, M. mendica, M. petulans, M. texana
Use by animals
Serves as larval food for the caterpillars of common buckeye butterflies[8] Agalinis species, including this one, host larvae of the common buckeye butterfly (Junonia coenia) in Florida.[9]
