Labellum broader and shorter than other Bunochilus in area. Lateral sepals shorter than others. Tobias debating whether umbrinus or another species.
Edit: added a photo to compare features.
Surely must be a toss-up between Pterostylis jonesii and Pt loganii. Maybe I'll send some images along to David Jones and Gary Backhouse to get their thoughts.
Have looked at this and I don't think this ticks all the boxes for B loganii so I'll put down as B montanus. However I'm not sure that this represents typical B montanus, so will be worth keeping an eye on these in future.
