Tucked away in a corner of London's Royal Botanic Gardens, there is a very peculiar plant. At first glance, it resembles a stumpy palm tree, but this ancient specimen is incredibly rare. It is, in fact, the very last of its kind on Earth. Encephalartos Woodii is a cycad. Over the millennia, the age of the cycad came to an end. This tree is the loneliest bachelor on Earth.
