It is an absolutely immensely enormous palm tree.

It has a trunk that can be almost a metre wide and it shoots up a stem of about 25 metres with a crown of massive fan-shaped leaves.

Each of those leaves is about five metres in diameter.

And then it has this astonishing flowering strategy whereby after decades of just growing trunk and leaves, it suddenly switches over to reproduction and produces what we would call the largest inflorescence or the largest flower bearing structure in the plant kingdom.

and it does it just once, so it's a fatal effort.

The really amazing thing about it is that

She told my colleague Julian Warricker why she got involved in this work.
