Political Region
It is not quite clear if O. strictum is distinct from O. novae-zeelandiae or should be regarded as a synonym. You can find the following statment in the NZNOG 2015 list (August Journal, No. 137 ): "The long floral bracts above the flower, and a more pointed labellum distinguish this Australian species from Orthoceras novae-zeelandiae. Actual distribution is unclear.”
