Description

Note the frilly margin of the labellum which is square and notched at the apex.(Distinguishes it from Microtis parviflora which has a non-frilly labellum that tapers to a point without the notch - triangular-shaped.)
Update: Close-up photos showing labellum detail added.
Note the variation in the shape/notching of the labellum. Some flowers only have minute notching on a square-ended labellum. Others have two rounded lobes with one shallow notch between them **but there is no gap or "decurved point" between the lobes**.
That makes it M. unifolia, I think, even though a proportion of the flowers have a bilobed labellum.
Looking at photos elsewhere, it seems that the id feature "labellum pendulous - not pressed against ovary" can be seen in both arenaria and unifolia.

  2. Chris Lindorff  This specimen is approaching M. arenaria and worth considering. Labellum well-notched and pendulous.
