Socratea exorrhiza, the Walking Palm or Cashapona, is a palm native to rainforests in tropical Central and South America. It can grow to 25 metres in height, with a stem diameter of up to 16 cm, but is more typically 15–20 m tall and 12 cm in diameter. It has unusual stilt roots, the function of which has been debated. Many species of epiphyte have been found growing on the palms. The palm is pollinated by beetles, and various organisms eat its seeds or seedlings.

HE. J. H. Corner in 1961 hypothesised that the unusual stilt roots of S. exorrhiza were an adaptation to allow the palm to grow in swampy areas of forest. No evidence exists that stilt roots are in fact an adaptation to flooding, and alternative functions for them have been suggested. John H. Bodley suggested in 1980 that they in fact allow the palm to "walk" away from the point of germination if another tree falls on the seedling and knocks it over. If such an event occurs then the palm produces new vertical stilt roots and can then right itself, the original roots rotting away.] Radford writes in the December 2009 Skeptical Inquirer that "As interesting as it would be to think that when no one is around trees walk the rainforest floor, it is a mere myth", and cites two detailed studies that came to this conclusion. Other advantages of stilt roots over normal roots have since been proposed. Swaine proposed in 1983 that they allow the palm to colonise areas where there is much debris (for example, dead logs) as they can avoid it by moving their roots. Hartshorn suggested in 1983 that stilt roots allow the palm to grow upwards to reach light without having to increase the diameter of the stem. The roots make the palm more stable and therefore allow it to grow taller and more quickly than if they did not possess them. They also allow the palm to invest less biomass in underground roots than other palms, therefore leaving more energy to be used in growing above ground. It was also thought that the roots may confer an advantage when the palm is growing on a slope, but no evidence has been found that this is the case.

sed to allow it to right itself after other plants collapse on it.

1 - the palm is growing normally.

2 - a tree collapses onto the palm and flattens the stem.

3 - new stilt roots form along the old stem and the original roots (dashed lines) start to die.

4 - the palm continues to grow normally but has now moved away from where it originally germinated…

그러나 잎이 많이 다른데 어찌 학명이 같을까? 정말 어렵다.
