Your plant has gone deciduous and is dormant. That is natural.
I never would've thought of connecting it with the genus Bletia. It looks very different from the Bletia species that I'm familiar with seeing. The only Bletia species I'm aware of are Bletia catenulata, Bletia florida, and Bletia purpurea.
Congratulations, this is definitely one of the rarer Bletia species that made it into the hobby. Good luck.
