The "Codex" features some plants that are not indigenous to Canada, for example the passion flower, named the by Nicolas. The caption for this particular illustration in the document reads 'qui produit les instruments de la passion'. Nicolas' representation of the passion flower shows the religious interpretation of the flower's anatomy, with parts of the flower representing various aspects of the passion of Christ. This flower is indigenous to South America, and is likely in the "Codex" as a curiosity, as it was popular among 16th- and 17th-century illustrators. The explicitly religious symbols incorporated into the drawing of the passion flower is another example of the various fictional creatures and marvels present in the "Codex".
