I bought this plant originally in bloom with a single growth and then mounted it on cork bark on the good advice

of my orchid friend who grows many Tolumnias.
[Unfortunately I cut off the original spike before my friend told me some rebloom from the same spike

]
Since then it has grown another growth and is now flowering again

[though it is flowering a little on the early side

as we're just beginning winter here in Australia]. I will have to go and measure it tommorow but I think these flowers aren't much bigger than my thumb.
If you can let them dry out I think it might be a good vivarium/orchidarium candidate

?
