This one is a great little terrestrial. It’s been renamed Polystachya neobenthamia so it’s no longer a monotypic genus. It gets about 2’ tall when grown in full Texas sun, but I’ve heard of specimens growing over 6’ tall looking for sun in shady conditions! Keep this in mind when growing it!
Yes they get HUGE. The greenhouse that I bought mine from has a mother plant that TOWERS over me and I'm 6' 4"😆
