Thaspium pinnatifidum (Buckl.) A. Gray, Man. ed. 2. 155. 1856

Thaspium Walteri Shuttl.; A. Gray, PI. Wright. 1: 79, as syn. 1852.
* Strict adherence to the International Rules of Botanical Nomenclature would appear to necessitate retention of the epithet trifoliatum for this variety. The authors feel that such procedure, since the variety is not based upon the type of the species, would result in confusion. The combination Thaspium trifoliatum (L.) A. Gray var. trifoliatum (Coult. & Rose) is therefore rejected as a nomen ambiguum. Plants 6 dm. high, puberulent; basal leaves deltoid in general outline, excluding the petioles 8-15 cm. long, ternate-pinnately dissected, the leaflets pinnately divided, the ultimate divisions linear-oblong to cuneate, 5-15 mm. long, 1-5 mm. broad, the margins entire; petioles slender, 1.5-2 dm. long; cauline leaves like the basal, the upper sessile; peduncles 1-6 cm. long; involucel of 1-several, linear, attenuate bractlets 3-6 mm. long, exceeding the pedicels; rays 13-16, subequal, 1.5-2 cm. long; pedicels 2-4 mm. long; fruit oblong-oval, 3-4 mm. long, 2-3 mm. broad, the ribs equally narrow-winged.
Type locality: "Banks of the French Broad River near the Warm Springs, and near Sugar Town Falls," Macon County. North Carolina. Buckley.
Distribution: North Carolina to Kentucky and Tennessee (Beardslee & 1 Kofoid 23).

Thaspium pinnatifidum

fornecido por wikipedia EN
Thaspium pinnatifidum, commonly called cutleaf meadow-parsnip,[1] is a species of flowering plant in the carrot family (Apiaceae). It is native to eastern North America where it is found in the southern Appalachian Mountains, being found in parts of Georgia, Kentucky, North Carolina, and Tennessee. Within these states it has a sporadic and limited range[2][3]
Its natural habitat is in dry to mesic forest openings over calcareous rock.[1][4]
This species is considered imperiled due to habitat loss via canopy closure, invasive species, and destructive roadside maintenance within its naturally narrow geographic range.[2]
Description
Thaspium pinnatifidum is an herbaceous biennial or perennial growing to about three feet high. Its leaflets are deeply dissected with many narrow divisions. It produces umbels of cream-colored flowers in late spring and early summer.[5]
It has often been confused with narrow-leaved forms of Thaspium chapmanii, which has led to over-mapping of its true range.[4]
