Identifying a Leggy Bird of Paradise Needing Repotting

what is this? Grandad's plant (died last week). Grew from seed over years. Don't know ID or care. Like banana but leaves different. Taller than ceiling. Leaves ~4 ft long, 1 ft wide. No bulb at bottom. Grows up from base in fan-like stems. No bark, no flowers.

Expert Advice

Appears to be a Bird of Paradise in dire need of larger container—hence lanky appearance. Healthy BOP has thicker main stem. Grows 20+ ft in ground (tropics), likes lots of water and direct light. Repot into larger container; will show true colors and eventually produce bird-like flower.
