Fig. 1. Fac-simile of a page of Porta's work (1591) showing similarities in plants to parts of animals, hound's-tongue (Cynoglossum), bugloss (Anchusa), hart's-tongue fern (Phyllitis), and adder's-tongue (Ophioglossum). It is interesting to note that two of Porta's names are still in use in a scientific sense, a third in a popular sense, while the fourth (Elaphoglossum) was later taken up for a genus of ferns distinct from the hart's-tongue of Europe.
