A new recorded location of this locally uncommon orchid

User's notes

I am hoping to get a species level ID on this one as all the others didn't have flowers open (at this point I hadn't been aware they only opened up when it was warm in the middle of the day). Another plant nearby with closed flowers

T. pauciflora or a related species; need a better view of the column and the leaf would help with id.

I have added leaf and crop. I can crop closer if needed

A broad ribbed leaf, pale blue column brown towards the top suggests T. arenaria.

If I added leaf photos to all my photos of unopened flowers would that be enough to get a more specific ID? If so I will add them, if it is the combination of the column and leaf that is nessesary I won't

Ryu,the flower is the critical thing, but sometimes the leaf in combination with the flower is helpful. Only very occasionally is it possible to identify an orchid to species level based on the leaf only.
