Kirk's Bush, near Papakura, Auckland.
On poroporo, at bush margin with Southern Park.
common terrestrial fern forming dense tall thickets in damp open forest sites.
Unsure - labellum appears triangular but not entirely smooth margin. M. unifolia growing reasonably close but I thought this plant looked quite distinct; at earlier floral development than surrounding M. unifolia, most of which are beginning to fruit
Common on seepages and in drains along roadside and above river.
