Thaspium Nuttall. Meadow-parsnip.

Key to Thaspium

A genus of 5-6 species, perennial herbs, temperate, of e. North America (Plunkett et al. 2018a). Thaspium and Zizia are closely related (sister to one another) and their traditional separation as genera should be re-evaluated.

Key advice:Because Thaspium and Zizia are often confused when not in fruit, a combined key emphasizing vegetative characters has been provided; it may also be helpful to use the key to genera, and if a clear answer is obtained, then use the Thaspium-Zizia combined key, skipping taxa of the "wrong" genus.
