Pinanga subterranea, a new species of palm discovered by researchers at the Royal Botanic Gardens, is one of only two known plants that exclusively fruit and flower underground.
There are more than 2,500 species of palm known to science, but Pinanga subterranea, a new species discovered on the tropical island of Borneo, is the only one that flowers and fruits only underground. The plant and its sweet fruits are well-known to the island’s indigenous population, but it has somehow been overlooked by scientists until now. Dr Paul Chai, a Malaysian botanist and namesake of the palm species Pinanga chaiana was the first to spot the underground-flowering palm, and in 2018, Kew scientists Benedikt Kuhnhäuser, Peter Petoe and William Baker took some samples for research purposes and discovered the plant’s amazing abilities.
