Botanists have discovered a new species of giant self-destructing palm in Madagascar which is so large that it can be seen in satellite photos, and Google Earth.
The plant, which only exists in the remote north-west of the island, is unlike anything else ever found on the island before. Although villagers had known about it for many years none had seen it flower.
The palm is 20m high with leaves 5m long, the tallest tree of its type in the country, but for most of its life - around 100 years - it is fairly unremarkable apart from its size.
The branches then become covered with hundreds of tiny flowers, which are pollinated and turn into fruit. But the tree expends so much energy on flowering that it eventually collapses and dies.
Dr John Dransfield, who is announcing the new discovery, is baffled as to how the tree came to be in the country. It bears a resemblance to a species of palm found in Asia but that is 6,000km away.
It is possible that the palm, which now numbers less than 100 examples, has quietly gone through a remarkable evolution since Madagascar split with India some 80m years ago.
