This is a cyanotype botanical illustration of the algae *Rhodomeria bifida*. The image is a deep teal-blue, characteristic of cyanotypes. Three specimens of the algae are arranged vertically on the page. The largest specimen is at the top and bottom, and a smaller one is centered between them. The algae has a complex, branching structure, resembling a delicate, feathery network. The branches are thin and intricate, creating a lace-like pattern. The cyanotype process has resulted in a slightly faded, ethereal quality, with the details of the algae rendered in varying shades of blue. At the bottom of the image, there's a small, rectangular label with the name 'Rhodomeria bifida' written in white lettering. The background is a uniform teal-blue, providing a stark contrast to the white-blue of the algae specimens.
