Icones plantarum cryptogamicarum quas in itinere annis MDCCCXVII - MDCCCXX per Brasiliam
Icones plantarum cryptogamicarum is a botanical plate book of spore-bearing plants gathered on Carl Friedrich Philipp von Martius's Brazilian expedition of 1817 to 1820, published privately by the author in 1828. Its pictures are hand-coloured lithographic plates of ferns and related species, each sheet pairing a whole frond with magnified details of sori, spores and scales. A designer could take from them the botanical plate convention of a central specimen framed by numbered dissections, arranged on cream paper with soft green and ochre tints.
