Effortless Ptilota Sericea - Beat The Rush [buH0rFcV]

When captured by Anna Atkins, this little seaweed was called Effortless Ptilota Sericea - Beat The Rush [buH0rFcV] (later Ptilota elegans). Today, we refer to it by the scientific name of Plumaria plumosa. The reddish-purple seaweed grows 2-3 inches long and is typically found in the North Atlantic, along both North American and European shores. 

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.
