Discussion

The type of Mulgedium pulchellum may be conspecific with that of M. tataricum (Linnaeus) de Candolle, a Eurasian species. Or, if “perennial” plus “Fl. blue” constitutes sufficient description for valid publication of the name Lactuca oblongifolia Nuttall (1813), then a new combination in Mulgedium based on that name may be appropriate for what is here called M. pulchellum. Presence of Mulgedium pulchellum in Texas is based on a single, early collection.
