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<ref name="radford">Radford, Albert E., Harry E. Ahles, and C. Ritchie Bell. Manual of the Vascular Flora of the Carolinas. 1964, 1968.

Agalinis fasciculata

Photo was taken by Gil Nelson
Scientific classification
Kingdom: Plantae
Division: Magnoliophyta - Flowering plants
Class: Magnoliopsida - Dicotyledons
Order: Lamiales
Family: Orobancheaceae
Genus: Agalinis
Species: A. fasciculata
Binomial name
Agalinis fasciculata
(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; A. fasciculata (Elliott) Rafinesque; 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). Flowers August to October.[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 (Entisols), flatwoods (Spodosols), upland pine communities and shortleaf pine-oak-hickory woodlands (Ultisols), 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 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 only in longleaf pine communities with soil disturbance by fire and not by agriculture.[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 flowers summer to fall[9][10]; however in the southern peninsula of Florida, it can flower all year[11]. Numerous small capsules each carrying hundreds of brown honeycombed seeds mature in late autumn.[5]

Michelle Smith observed Agalinis fasciculata flowering along Piney Z Lake in Tallahassee, Florida in September 2015 & flowering at Pebble Hill Plantation in Grady County, GA in October 2015.

Agalinis fasciculata has been observed to flower in May and July to December, with peak inflorescence in September and October.[12]

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

The following Hymenoptera families and species were observed visiting flowers of Agalinis fasciculata at Archbold Biological Station:[16]

Colletidae: Hylaeus confluens

Halictidae: Augochlorella gratiosa

Megachilidae: Megachile albitarsis

Use by animals

Agalinis species, including this one, host larvae of the common buckeye butterfly (Junonia coenia) in Florida.[17]

Conservation and management

A. fasciculata is listed as endangered in the state of Maryland and is listed as rare in the state of New York.[18]
