Tag reads Dendrobium tannii - web search indicates this might now be classified as bracteosum var. tannii, or, maybe even a cultivar of bracteosum ?

Anyhoo ... smaller than typical bracteosum - the biggest cane on mine is about 2" in height, 2" leaves, 1" flowers.
I got this in bloom (a few spikes blooming) in April. I was (happily) surprised when 2-3 months ago I spotted a new spike

It's been growing in a west facing window that gets some direct sun mid-late afternoon. Watered when nearly dry or dry.
Actual color is both more saturated and brighter than appears in photos - One reason I've not posted bloom photos the past several months is my frustration at not being able to capture colors well *sigh*

The last photo is probably the closest to the actual color, tho still not as bright nor saturated.
Thanks for looking
