A study published in Nature involving over fifty institutions around the world has found that New Guinea has more than 13,000 plant species, ranging from tiny orchids to giant tree ferns, two-thirds of which do not exist anywhere else - and there are many thousands more species yet to be discovered. Tim Utteridge, a botanist at the Royal Botanic Gardens, Kew, in the UK, and head of the Identification and Naming department explains why New Guinea has such an amazingly high diversity of plants and the how travelling to the sites on the island can take as long as a week.
