Scientific classification
Kingdom: Plantae
Division: Tracheophyta - Vascular plants
Class: Magnoliopsida – Dicotyledons
Order: Lamiales
Family: Plantaginaceae
Genus: Nuttallanthus
Species: N. floridanus
Binomial name
Nuttallanthus floridanus

Nutt flor dist.jpg
Natural range of Nuttallanthus floridanus from USDA NRCS Plants Database.

Common names: Apalachicola toadflax; Florida toadflax[1]

Taxonomic notes

Synonym: Linaria floridana Chapman.[1]

Varieties: none.[1]

The genus Nuttallanthus was separated from Linaria in 1988 by Sutton due to the floral and seed characteristics. [2]

Description

This species is an annual herb that produces bluish, bilabiate, and spurred flowers that attract a variety of insects.[2]

Distribution

N. floridanus is a narrowly distributed species occurring in the Atlantic and Gulf coastal plain in Alabama, Florida, Georgia, and Mississippi.[2]

Ecology

Habitat

Habitats include sparsely vegetated white sands along lakes, scrubs, sand dunes, and dry sandhills.[3] It has been observed growing in disturbed areas such as roadsides. Associated species include Krigia virginica and Crocanthemum.[4]

Phenology

This species flowers and fruits in March.[4]

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.[2]

Seed dispersal

The seeds are small and lack obvious dispersal mechanisms.[5]

Seed bank and germination

Carrington (1997) found that germination depends on seeds accumulated in a persistent seed bank to maintain populations between disturbances.

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.[2] The following Hymenoptera species were observed visiting flowers of Linaria floridana at the Archbold Biological Station:[6]

Sweat bees from the family Halictidae: Lasioglossum nymphalis, Lasioglossum pectoralis, Lasioglossum puteulanum

Leafcutting bees from the family Megachilidae: Anthidiellum notatum rufomaculatum, Megachile brevis pseudobrevis, Megachile georgica, Osmia sandhouse

Thread-waisted wasps from the family Sphecidae: Tachysphex similis
