Summary

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.

Cultivation

Nothing derived: no habitat climate for this species.

Climate across the habitat

No habitat climate can be derived: Native range not verified: no WCVP distribution with native status for this name, so records cannot be told from cultivation and no habitat climate is derived. 7 of the 9 in-range records are placed to worse than 10 km, or to no stated accuracy and fewer than three decimals or by something other than a person's observation, and cannot place a climate cell, though they count for the map and its marker.

Natural habitat

No native range: WCVP lists no region where it is native.
Openly licensed records, not tested against the stated range, framed on where they fall.

Extinct inNorth Carolina · recorded as extinct by WCVP: history, not habitat; no records are tested against these regions
Kew's description“perennial” · “temperate” · quoted from WCVP, RBG Kew (CC BY 4.0); not derived here
Evidence usedNo verified native range for this name: WCVP has no entry with native status, and a checklist that only reports presence cannot tell a wild record from a garden one. The map shows 7 openly licensed records of 9 untested against any range; no map marker or climate is derived from them, and no sheet is built from them. 7 in-range records are placed to worse than 10 km, or with no stated accuracy (admitted only as a person's observation to three decimals), and stay on the map but off the climate.

Every source is recorded as having answered, reported nothing, refused, failed, not been asked, or answered twice where one answer is taken (“not taken: two items answered”), and, for a source asked when this page was built, when: the figures are as the source held them that day; a source read from a file (Kew's World Checklist, a GBIF download) says "as of" the file's day instead; a row carried from an earlier build of the page names that build instead. Only “nothing to report” is ever shown as an absence. Records came from 5 datasets via GBIF.org; each carries its own licence.
