Description

Endemic to the Southeast U.S., A. georgiana is an annual forb that is a member of the Scrophulariaceae family. [2] Like all other members of the Agalinis genus, A. georgiana is a root parasite, which is a type of hemiparasite that penetrates roots of neighboring plants to transfer food and water from the host plant. However, they are semiparasitic since they still contain their own chlorophyll and can produce their own food as well. [3] A. georgiana is glabrous, with bright green herbage, and contains pale corollas that lack spots and lines within.[4]

Distribution

A. georgiana is distributed from south Georgia and Alabama down to the western panhandle of Florida.[1]

Ecology

Habitat

Observed in dry and well-drained upland longleaf pine savanna communities, and shady sandy loams of pine-oak woods. [5] In these communities, A. georgiana can be quite frequent in the understory composition. [6] It can also be found in bogs. [7]

Associated Species: Pinus palustris, Quercus falcata, Diospyros virginiana, Ilex glabra, Agalinis obtusifolia, and Ctenium aromaticum. [5]

Agalinis georgiana is an indicator species for the Upper Panhandle Savannas community type as described in Carr et al. (2010).[8]

Phenology

Agalinis georgiana has been observed to flower in the months of September and November.[5][9]


Fire ecology

A. georgiana has been recorded in longleaf pine savannas that are burned annually.[5]


Use by animals

Agalinis species, including this one, host larvae of the common buckeye butterfly (Junonia coenia) in Florida.[10]
