Caladenia xantholeuca D.L. Jones, 1991
Flinders Ranges spider-orchid, White rabbits, Flinders Ranges white caladenia, Flinders fingers
Taxonomy & Nomenclature
"Not seen since 1982 despite targeted searching; could be taxonomic issues based on photos - very similar to a co-occurring species."
(Silcock et al., 2019:SM:1)
Conservation Status
Rediscovered (source) or taxonomically suspect (Silcock et al., 2019:SM:1)
Last record: 1982 (Silcock et al., 2019:SM:1)
Rediscovered in 2011 (source; not recognised by Silcock et al., 2019:SM:1)
Not seen since 1982 (Silcock et al., 2019:SM:1), with a reported rediscovery of the species based upon a photograph taken by a member of the public initially confirmed by Cathy Houston and Bob Bates (source). However, Bob Bates was one of the experts later consulted by (Silcock et al., 2019:SM:1) who note "could be taxonomic issues based on photos - very similar to a co-occurring species", implying (along with their reporting of the last record as 1982) that the species was not infact rediscovered.
