DistributionCollected twice only, in 1891 near Heilig's Mill in Rowan County and pre-1965 in Orange County. There is no specimen of the latter in SERNEC, but RAB (1968) cites the county and BONAP maps it.

Native of Eurasia; in N.A. Que. to Ont. south to FL and TX; also AZ, OR, B.C.
AbundanceVery rare, if still present as an escape.
HabitatVicinity of mill.
PhenologyFlowering and fruiting May-July.
IdentificationShould anyone rediscover this long-lost alien, it will be easy to identify, due to the elliptical leaves (acute at the tip, rounded at the base) that are sessile at the base and on the lower part of the stem, but are perfoliate up-stem. There are very few NC plants with obviously perfoliate leaves. The umbels are small and yellow-flowered.
