Calystegia sepium binghamiae (Greene) Brummitt
Bingham's morning-glory, Bingham's false bindweed, Santa Barbara morning-glory
Taxonomy & Nomenclature
Synonym/s: Convolvulus binghamiae Greene; Calystegia binghamiae Greene
Conservation Status
Extinct (Rejmánek, 2018; Smith, 2018; Knapp et al., 2020, 2021)
Last record: 1899; 1902 (Rejmánek, 2018; Knapp et al., 2021)
Mistakenly thought to have been rediscovered twice, in March 1965 and 2012 (or April 2011) (Rejmánek, 2018). That material was later used as the basis for the description of a new taxon, C. felix (Provance & Sanders, 2013).
