Agalinis skinneriana is a species of flowering plant in the family Orobanchaceae known by the common names Skinner's gerardia,[2] Skinner's false foxglove and pale false foxglove. It is native to North America, where it occurs in Ontario south to Missouri and Louisiana.[3]

Description

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.[1] The flowers are visited by bees.[4] However, each flower is open for only a few hours and it may pollinate itself.[3] This plant is similar to and difficult to distinguish from several other Agalinis.[1]

Habitat

This plant grows on prairies.[4] It can also be found in woods, barrens, and thickets.[3] 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[3] The plant often grows in habitat maintained by a regime of periodic wildfire.[1] Fire suppression is a threat to it.[3]
