Agalinis skinneriana is a species of flowering plant in the broomrape family known by the common names Skinner's gerardia,[1] Skinner's false foxglove and pale false foxglove. It is native to North America, where it occurs in Ontario south to Missouri and Louisiana.[2]
This plant is an annual herb with four-angled stems growing up to 40 centimeters tall. The linear leaves are oppositely arranged and each is up to 2.5 centimeters long. The inflorescence is a raceme of pink or white flowers each up to 1.6 centimeters long. Blooming occurs in August through October.[3] The flowers are visited by bees.[4] However, each flower is open for only a few hours and it may pollinate itself.[2] This plant is similar to and difficult to distinguish from several other Agalinis.[3]
This plant grows on prairies.[4] It can also be found in woods, barrens, and thickets.[2] It is associated with other plants such as Agalinis purpurea, Aletris farinosa, Andropogon gerardi, Aster ptarmicoides, Calopogon tuberosus, Liatris spicata, Lobelia kalmii, Pycnanthemum virginianum, and Solidago ohioensis[2] The plant often grows in habitat maintained by a regime of periodic wildfire.[3] Fire suppression is a threat to it.[2]
