Gleichenia immersa, Jamaica
The Gleichenia immersa that Anna Atkins documented has gone by several other names, but is best known as the umbrella fern. The most common type of umbrella fern is native to Australia and New Zealand, but many kinds appear across the globe.
Atkins created her cyanotype photograms by placing the specimen onto light-sensitive paper, and then exposing paper and subject to the sun for a period of time. She then developed the image using the cyanotype process, resulting in a rich blue background.Â
