Common names: Beach False Foxglove; Cluster-leaf Gerardia
Synonym names: Gerardia fasciculata Elliott; A. fasciculata (Elliott) Rafinesque; Gerardia fasciculata ssp. typica – P; Gerardia fasciculata ssp. peninsularis (Pennell) Pennell
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.
The stems are similar to Agalinis purpurea, but instead are scabrous to scaberulous (not puberulent). Flowers August to October.
It is common in all of Florida. Found from: west to Texas, north to North Carolina.
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, and on the borders of dunes. It occurs on a wide range of soil types from deep sands to loamy clay. It requires high light provided by frequently burned areas. 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.

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.
According to Kay Kirkman, a plant ecologist, this species disperses by gravity.
