South Georgia's flora is particularlly rich in cryptogams. While hiking across hills and mountains in South Georiga for interesting soil sampling spots, I also came across a lot of beautiful lichens. Common lichen genera were Caldonia, Usnea and Diploschistes. There are also several fern species growing in South Georgia and hude amount of moss species, which often cover whole streams; so called "moss streams".
