Burma, with rainfalls in its various districts of 20 to 225 inches from June to October and with habitats from sea level up to 18,000 feet, has a very rich fern flora. The country is so located that many fern of both the China-Himalayan and the Malayan regions occur in the country. This article, originally published in the Ohio State Journal of Science in May 1946, catalogues over 400 different ferns belonging 104 genera discovered in the period up to the Second World War. The writer, Frederick Garrett Dickason, personally collected over 325 kinds of ferns in various parts of Burma which were on display in the Herbarium of Judson College in Rangoon where he taught for many years. A useful map accompanies the article.
