(Elliott) Raf.
AGAL FASC dist.jpg
Natural range of Agalinis fasciculata from USDA NRCS Plants Database.

Common names: Beach false foxglove; Cluster-leaf gerardia

Taxonomic notes

Synonyms: Gerardia fasciculata Elliott; Gerardia fasciculata ssp. typica; Gerardia fasciculata ssp. peninsularis (Pennell) Pennell.[1]

Description

Annual. Parasitic to the roots of grasses and other herbs. Leaves are opposite, linear to filiform, and sometimes will have tufts on the shoots. Flowers are showy, in terminal racemes; the calyx is 5-parted, the lobes are shorter than the tube; the corolla is 5-parted. The flowers are rose-lavender in color and are rarely white. There are usually 2 yellow lines and numerous purple spots in the throat on the tube. The tube is broad, campanulate, and the lobes are shorter than the tube. The throat is usually lanose at the base of the 2 upper corolla lobes. There are 4 stamens, didynamous, that include filaments and anthers that are also lanose. The stigmas are elongated. The capsules are globose or subglobose, loculicidal.[2]

The stems are similar to Agalinis purpurea, but instead are scabrous to scaberulous (not puberulent).[2]

Distribution

It is common in all of Florida. Found from: west to Texas, north to North Carolina[3]

Ecology

Habitat

It can be found in frequently burned pine sandhills, flatwoods, upland pine communities and shortleaf pine-oak-hickory woodlands, as well as calcareous glades, sandhills, coastal scrubs, margins of ponds, lakes, depressions, marshes, and wet meadows, on the borders of dunes[2][4][5] and in pine rocklands.[6] It occurs on a wide range of soil types from deep sands to loamy clay. It can occur on very disturbed soils, such as those in railroad and power line rights-of-way, clear-cut areas, disturbed roadsides, dredged up sand, and site-prepped pine forests. It appears to be somewhat salt tolerant given its proximity to salt marshes and co-existence with Spartina bakari and other brackish-salt water plants[5][4] It is considered by some sources to be an early successional species in post agricultural succession.[7] A. fasciculata is observed to do well in burned longleaf pine communities, but it experiences reduced occurrence under agricultural disturbance. Additionally, A. fasciculata shows resistance to regrowth in reestablished longleaf communities that were disturbed by agricultural practices.[8].


Associated species includes Bidens, Chrysopsis, Eupatorium, Schoenus nigricans, A. longespica, Houstonia nigricans, Rynchospora divergens, Scleria verticillata, Juniperus, Haplopappus, Rubus, Gnaphaluim, Eupatorium compositifolium, Baccharis, Andropogon, Xyris, Polygala, Solidago, Trichostema, Spartina bakeri, Myrica cerifera, Euthamia minor, Baccharis angustfolia, Hyptis, Lycopus, Drosera, and Pinus palustris.[4]

Phenology

It mostly flowers from summer to fall with peak inflorescence in September and October[9][10][2][11]; however, it has been observed to flower as early as May and late as December[11] and in the southern peninsula of Florida it can flower all year[12]. Numerous small capsules each carrying hundreds of brown honeycombed seeds mature in late autumn.[5]

Seed dispersal

This species is thought to be dispersed by gravity.[13]

Seed bank and germination

The seeds observe physiological dormancy, are cold stratified, and germinate at 20/10 C in light.[14]

Fire ecology

A. fasciculata requires high light provided by frequently burned areas. [15]

Pollination and use by animals

Agalinis fasciculata has been observed being visited by pollinators such as Hylaeus confluens (family Colletidae), Augochlorella gratiosa (family Halictidae), and Megachile albitarsis (family Megachilidae).[16] Additionally, this species has been observed to be visited by the pollinator Perdita gerardiae (family Andrenidae).[17] Other species of Agalinis, including this one, host larvae of the common buckeye butterfly (Junonia coenia) in Florida.[18]

Conservation, cultivation, and restoration

A. fasciculata is listed as endangered in the state of Maryland and is listed as rare in the state of New York.[19]
