Marcgrave registered 15 animal species and 12 vegetable species and Piso observed 23 vegetable species associated to several places. These results, when compared with the totality of their descriptions and observations on plants and animals, they indicate thedeliberate intention of not informing the places, probably for reasons of the governmentsfrom Dutch Brazil safety.
