This intricate black-and-white botanical engraving depicts a fern in full life cycle: mature fronds (fr), young coiled fiddleheads, rhizome with roots (A), sori-bearing leaflets (B), a single sporangium with annulus (D), and a cross-section of sorus tissue (C) showing sporangia (s), indusia (i), and paraphyses (p). The fine linework captures both morphological detail and taxonomic precision typical of 19th-century scientific illustration.
