Description
Common names: Slender Garardia; Slenderleaf False Foxglove
Synonym names: A. tenuifolia var. leucanthera (Raf.) Pennell; Gerardia tenuifolia Vahl; Gerardia tenuifolia subsp. lecuanthera (Raf.) Pennell
It is an annual (Hogg et al 1983 and Hall 1993).
Distribution
Agalinis tenuifolia is the most widely distributed throughout eastern North America (Musselman and Mann 1978).
Ecology
This species is a vigorous parasite. It formed haustoria on all 19 commercial species included in Appendix III. No clear host preference was shown, although hardwood species supported more parasitic attachments than pine species (Musselman and Mann et al 1978).
Habitat
Agalinis tenuifolia commonly grows in disturbed sites, including clear cut areas and the edges of pine plantations. Large populations may also be found growing at the margins of ditches and in other wet or moist habitats (Musselman and Mann 1978). It can be found in undisturbed grasslands and areas with low soil nutrients (Hogg and Morton 1983). Other natural habitat includes open upland woodlands, mixed pine-hardwood stands, mesic wooded edges of limestone glades and open grassy limestone glades, scrubby floodplain woods, borders of wooded mesic hammocks, dry sandy slopes, and calcareous clearings (FSU Herbarium). It occurs on xeric limestone prairies of Illinois (Hogg et al 1983), and in moist to dry savannas and bluffs (Wunderlin and Hansen 2003). Prefers semi-shade and sandy soils including sandy loam, sandy clay, and drying or dry loamy sand (FSU Herbarium).
Phenology
Seed dispersal
Seed bank and germination
Fire ecology
Pollination
Use by animals
Native vegetation, often including Agalinis tenuifolia, can be completely destroyed and replaced by weeds and soil nutrients increase dramatically when Ring-billed Gulls and other species of gulls nest from April to June (Hogg et al 1983).
