White chervil

Cryptotaenia canadensis, commonly known as Canadian honewort or wild chervil, is a slender perennial herb in the family Apiaceae native to eastern and central North America, ranging from Quebec and New Brunswick south to Georgia and Texas, where it inhabits moist deciduous woodland, shaded floodplains, and rich bottomland thickets. The plant grows from a slim taproot and produces erect, smooth, slender, branching stems 30 to 90 centimetres tall. The leaves are alternate and trifoliate, the leaflets ovate to rhombic, 4 to 10 centimetres long, with sharply and irregularly double-serrate margins and pointed apices; the terminal leaflet is often three-lobed. Tiny white flowers 1 to 2 millimetres across are borne in loose, irregularly compound umbels with only two to five primary rays of unequal length, terminating in few-flowered umbellets without conspicuous involucral bracts. The fruits are narrow oblong-elliptic schizocarps 5 to 8 millimetres long that split into two ribbed mericarps when mature. The foliage has a mild celery-parsley aroma when bruised.
