Point 5834

I've cofirmed this Michael mainly on the basis of general appearance and because D. sulphurea is about the only Diuris on BM still at flowering stage.

I think it is Microtis, but can't really tell from the photo if the leaf is hollow. Plenty of Mocrotis starting to appear, and I have confirmed it as such.

It's hard to be sure from the photo, but I think it's probably Microtis as you suggest. What do you think, Tony?

I think you can even see remnants of beard in image 3.

I agree with Aaron. The part of the fruit above the main fruiting body seems a little long for Thelymitra. I have some images of Calochilus fruit I am yet to upload, and they look identical to Michael's images. As they were among Thelymitra, I was able to compare the two.
