(Band 2,1): Fünftes Heft. oder des zweitenTheils erstes Heft
This 1802 German fifth part of a seaweed volume by Eugen Johann Christoph Esper, held by Heidelberg University Library, consists of hand-coloured plates of marine algae for naturalists and botanical students. The plates show red and brown seaweeds drawn as separate specimens with fine branching fronds, cushion-like crusts and forked stalks, labelled with figure numbers, offering a designer clear botanical silhouettes and organic branching forms for pattern and linework.
