Conservation status of New Zealand indigenous vascular plants, 2012
The conservation status of all known New Zealand vascular plant taxa at the rank of species and below were reassessed in 2012 using the New Zealand Threat Classification System (NZTCS). This report includes a statistical summary and brief notes on changes since 2009 and replaces all previous NZTCS lists for vascular plants. Authors: Peter J. de Lange, Jeremy R. Rolfe, Paul D.

TAXONOMIC NOTES

Jones et al. (2001) revived the genus Petalochilus R.S.Rogers (erected by Rogers (1924) for what has come to be viewed as a peloric state of Caladenia R.Br. - see Moore & Edgar (1970)) for a distinct clade of mostly New Zealand orchids that had usually been referred to as Caladenia. Subsequently Hopper et al. (2004) showed how the reorganisation of Caladenia by Jones et al. (2001) was unworkable and they recommended a return to Caladenia and the other allied Australian genera that had been recognised previously. Following discussion with S. Hopper and P. Weston (pers. comm., 2011, 2014) the treatment of Hopper et al. (2004) is preferred to that of Jones et al. (2001) and so followed here.

Caladenia minor remains somewhat of an enigma and the correct application of the name is uncertain. It is for this reason that this fact sheet has not been populated. Clarification of the exact application of this name and whether it involves one or more Caladenia currently recognised under other names requires critical evalutation.
