Dictyosiphon foeniculacea [= Dictyosiphon foeniculaceus] c. 1843 - 1853

Anna Atkins, a pioneer of photography, created this cyanotype print of *Dictyosiphon foeniculacea* c. 1843-1853. The image captures the delicate, feathery structure of the seaweed, showcasing Atkins’ interest in documenting the natural world. This cyanotype, with its characteristic blue background and white details, is a prime example of Atkins’ innovative use of the photographic process to create botanical illustrations. This work was part of her groundbreaking *Photographs of British Algae: Cyanotype Impressions*, which she published between 1843 and 1853.
