Scientists have discovered an alternative water transport system in a screw pine tree (Pandanus forsteri) from Lord Howe Island, off the coast of Australia. Their findings were published August 1 in Proceedings of the Royal Society B. The tree’s aerial roots take years to reach soil, which prompts its use of a different mechanism of obtaining water; its leaves direct rainwater through channels to the tips of roots that store it in absorptive tissue.
