In 2005 whilst at the Allan Herbarium (CHR), Lincoln I happened to ask Dr David Glenny if anyone had examined the liverwort flora of the Chatham Islands? David told me that a few people had collected liverworts from there, including him in 1997, and so far found “nothing special”. Intrigued, I then asked if David would like me to collect hornworts and liverworts while doing vascular plant work over there, and he agreed that this would be a good idea. David also kindly gave me a checklist of the hornworts and liverworts known to be on the island, and further, he agreed to identify what I got from there.
