There is a chance that if you killed all the roots, this species will do one of two things:
1. Tolerate the lack of roots and send out new ones. This doesn't happen very often.
2. Form new growths at the leaf node. I find this is quite common if a shoot or older piece of the rhizome either lacks roots is stressed.
On this high elevation Venezuelan species, it is better to underwater than overwater. Keep it in cooler temperatures with high humidity, but avoid keeping the plant sitting with roots constantly moist. Do you have any pictures of the plant?
