Lastreopsis dissecta (C.T.White & Goy) Labiak, Sundue & R.C.Moran (2014:84)

Taxonomy & Nomenclature

Synonym/s: Leptolepia dissecta C.T.White & Goy in Vict. Naturalist 54: 149, t. 15(1) (1938); Oenotrichia dissecta (C.T.White & Goy) S.B.Andrews in Austrobaileya 1(1): 12 (1977)

Treated as a valid taxon by (Hassler, 2004-2023), but noted as being taxonomically problematic by (Field & Renner, 2019:116), who suggest that it may either represent an extreme form of L.  tripinnata or a hybrid of that species with L. tinarooensis. Silcock et al. (2019:SM:5) similarly note:

"Apparently sound (specimen examined; Oenotrichia tripinnata also occurs in area, so could be a freak or hybrid - impossible to say without more material)"

Conservation Status

Missing if valid (Silcock et al., 2019:SM:5 [as 'Possibly extant']) or Extinct if valid (Field & Renner, 2019:116)

Last (and only) record: September 1936 (Field & Renner, 2019:116 [as September 1936]; Silcock et al., 2019:SM:5 [as 1936])

Distribution & Habitat

Mount Spurgeon Tableland, north-eastern Queensland, Australia (Field & Renner, 2019)

"on rock faces in damp places near creeks"

(Silcock et al., 2019:SM:5)
