That's big for T.pauciflora, i'd be tempeted to say T.nuda or allied.

@tapirlord late to the party, but I would put my money on T megcalyptra, given the size and the unpinched post-anther lobe. I've found T megcalyptra here 2 years running (though I seem to have missed it this year, darn), and I see another was found nearby. Thoughts? @DerekC ?

I think my first thoughts had been the principle flower and what I could see of the leaves. I assume by pinched you are referring to what others call inflated post anther lob or in this case your suggesting not inflated? I think these post anther lobes are inflated but that is true for both these species as are the column arms converging and toothbrush shaped. One distinguishing feature of T. megcalyptra is petals not overlapping the sepals. In the major flower represented this not true but I now notice flowers lower down and opened longer do display this feature. The guide booking I am quoting that from though making that statement also its main photo does not support this either. I suspect like a number of these things what you are looking for evolves over several days, with us easily fooled. The leaf was the other issue, of the two plants one appears to have a reasonable narrow leaf unlike what I expect typical of T. megcalyptra. But the larger plant has a much broader leaf and if I am correct short. Both are quite green where T. megcalyptra can be quite orange-red and before flowering. The suggested small flower size of 30mm would be, if correct, much smaller than T. megcalyptra's 45mm across. I guess all I have done is repeat my . One thing these flowers do have a tendency to do is over open or the tepals get a bend towards the inner edge then bend backwards further open which is true of T. megcalyptra.
