Adlumia fungosa (Aiton) Greene ex Britton, Sterns, & Poggenburg. Common name: Alleghany-vine, Cliff-Harlequin, Climbing Fumitory. Phenology: Jun-Sep. Habitat: Cliffs, talus, rocky slopes, rich stream-bottom forests, cool rocky forests, burned areas, especially over calcareous or mafic rocks. Distribution: QC west to WI and MN, south to n. DE, w. NC, TN, and IN. Reported for Plaquemine Parish, LA (Allen 2017), a location that seems biogeographically implausible to be a native occurrence.

Origin/Endemic status: Native

Other Comments: The seeds are apparently long-lived and are scarified by fire; the species appears after fires where not previously apparent (R. Allen, pers. comm., 2017).

Delicate, vining biennial that scrambles over other plants and into trees, found on cliffs, talus, rocky slopes, rich stream-bottom forests, cool rocky forests and burned areas, especially over calcareous or mafic rocks.
Stems climbing, smooth; in its first year a plant is essentially stemless, with only several upright leaves.
Leaves alternate, petiolate, 2 times pinnately divided, pale green beneath; reduced in size at the upper reaches of the vine, where leaves act like tendrils.
Flowers in drooping clusters from leaf axils, white to pale pink, 1/2-2/3 in. long, bilaterally symmetric and tubular, shaped like upside-down vases with a pair of tiny, scale-like bracts at the flower base (which is on top) and 2 spreading lobes at the mouth of the vase.
Fruit a narrow, oval capsule.
