Taxonomic notes
Synonym: Linaria floridana Chapm.
The genus Nuttallanthus was separated from Linaria in 1988 by Sutton due to the floral and seed characteristics (Phillip and Elisens 2006).
Description
This species is an annual herb that produces bluish, bilabiate, and spurred flowers that attract a variety of insects (Phillip and Elisens 2006).
Distribution
N. floridanus is a narrowly distributed species occurring in the Atlantic and Gulf coastal plain in Alabama, Florida, Georgia, and Mississppi (Phillip and Elisens 2006).
Ecology
Habitat
Habitats include sparsely vegetated white sands along lakes, scrubs, sand dunes, and dry sandhills[1]. It has been observed growing in disturbed areas such as roadsides. Associated species include Krigia virginica and Crocanthemum (FSU Herbarium).
Phenology
Flowers and fruits in March (FSU Herbarium).
It is an autogamous species and produces both cleistogamous and chasmogamous flowers. The cleistogamous flowers are produced early and late in the life cycle and the chasmogamous flowers are self-pollinated before anthesis and attract insects after anthesis (Phillip and Elisens 2006).
Seed dispersal
The seeds are small and lack obvious dispersal mechanisms (Carrington 1997).
Seed bank and germination
Carrington (1997) found that germination depends on seeds accumulated in a persistent seed bank to maintain populations between disturbances.
Fire ecology
Pollination
Pollen is required for fruit and seed development. It is completely cross-incompatible with other Nuttallanthus species due to the amount of genetic divergence between species and isolation (Phillip and Elisens 2006).
