Roodhoorntjeswier before 1892

"Roodhoorntjeswier" (Red Horned Algae) is an illustration of a *Ceramium rubrum* (red algae), a species commonly found in coastal waters. Created by an anonymous artist before 1892, this delicate drawing uses fine lines and a subtle palette of browns and reds to depict the intricate branching structure of the algae. Its meticulous detail and scientific accuracy suggest it was intended for a botanical or scientific publication, providing a valuable record of the species for researchers and naturalists.
