Yellow Pimpernel Taenidia integerrima (Linnaeus) Drude  Synonyms: Yellow-pimpernel.

Status:

Yellow Pimpernel is a locally common plant over much of the ridge and valley and Allegheny Plateau. Most of the piedmont records are not recent except for a handful from Montgomery County. Yellow Pimpernel seems to prefers dry woodlands and areas with rocky calcareous substrates. Yellow Pimpernel can be very common in shale barrens of Allegany and Washington Counties. The Kent County record is from an ancient oyster shell midden that holds many unusual western shore plant species.

Description:

Yellow Pimpernel is very similar to the rare shale barren endemic Mountain Pimpernel. Weakley's Key to the Flora of the Southern and Mid-Atlantic States, 2015 states that there are two ways to separate the two yellow pimpernel species: The fruit of Yellow Pimpernel is not winged and the fruit of Mountain Pimpernel is winged. When plants are fresh the crushed leaves of Yellow Pimpernel smell of celery and the crushed leaves of Mountain Pimpernel smell of licorice/anise.

There are 36 records in the project database.
