Conservation Status
Missing (Wood et al., 2019:9) or Extinct (Stone, 1967:235,236; WCMC, 1998; Wagner et al., 1999:41; Baillie & Butcher, 2012:88; Humphreys et al., 2019; Albani Rocchetti et al., 2022; Christenhusz & Govaerts, 2024; POWO, 2024)
Last record (disputed): 1850's (Christenhusz & Govaerts, 2024); 1870 (NatureServe, 2024); 1888 (or shortly afterwards) (WCMC, 1998); c.1900 (Wood et al., 2019:9)
IUCN RedList status: Extinct
"Kokia lanceolata, a somewhat dubious species, is certainly extinct; its habitat was arid southeast Oahu."
