Musa indandamanensis

Context

The Musa indandamanensis, a wild banana species endemic to the Andaman and Nicobar Islands, has produced the world’s longest banana infructescence (fruit bunch axis) — measuring about 4.2 metres. This marks a significant botanical record and sheds light on the rich but lesser-known biodiversity of the Andaman and Nicobar Islands.

What is an infructescence?

  • Infructescence is the fruiting structure (or fruit bunch) that develops from an inflorescence (flower cluster).
  • In bananas, it’s the long axis bearing all the banana fruits.
  • Typically, the infructescence of cultivated bananas is about 1 metre
  • This wild banana species has an infructescence of 2 metres, the longest ever recorded.
