Marshallia grandiflora
Also called Barbara's Buttons, Appalachian Barbara's Buttons, Large Flowered Barbara's Buttons
Marshallia grandiflora, the Appalachian Barbara's buttons, is an extinct species of flowering plant in the genus Marshallia within the sunflower family. It was endemic to the Blue Ridge Mountains of North Carolina in the Eastern United States, in Henderson and Polk counties. It was found primarily along gravelly and sandy bars along high-gradient rivers, and was presumably wiped out due to changes in this restricted habitat. It was last sighted in 1919.
Marshallia grandiflora was an herb up to 90 cm (3 feet) tall. Most of the leaves were clustered around the base of the stem. One plant would produce one or two heads, each head containing pink disc flowers but no ray flowers.
