Looking into the flora of Dutch Brazil: botanical identifications of seventeenth century plant illustrations in the Libri Picturati.

The Libri Picturati includes a collection of plant illustrations from seventeenth century Dutch Brazil that is kept in the Jagiellonian library in Krakow since World War II. While many studies focused on the artistic details and history of these images, we identified the flora depicted. We used contemporary textual sources (e.g., Historia Naturalis Brasiliae), monographs and taxonomist' assessments. We checked origin, life form, domestication and conservation status and the plant parts that are represented. We identified 198 taxa, consisting mostly of wild, native rainforest trees and 35 introduced species. Fertile branches are the most represented, although some loose dry fruits and sterile material were also painted, which sheds light into the collection methods by naturalists in Dutch Brazil. Several species are no longer abundant or have become invasive due to anthropogenic influences since colonialism. Through this botanical iconography, we traced the first records of the sunflower and the Ethiopian pepper in Brazil, as well as the dispersion and assimilation of the flora encountered in the colony by Indigenous, African and European peoples. We emphasized the relevance of combining visual and textual sources when studying natural history collections and we highlighted how digitalization makes these artistic and scientific collections more accessible.

What's in a name? Revisiting medicinal and religious plants at an Amazonian market.

BACKGROUND: In spite of an increasing number of ethnobotanical market surveys in the past decades, few studies compare changes in plant species trade over time. The open-air market Ver-o-Peso (VOP) in Belém, located near the mouth of the Amazon River in the state of Pará, Brazil, is known for its wide variety of medicinal plants. A survey of VOP was published in 1984, but it remains unknown to what extent its botanical composition changed over 34 years. Furthermore, in northern Brazil, little attention has been given to the origins of the vernacular names of these plants. Our aim is to give an up-to-date overview of the VOP medicinal plant market, concentrating on changes in species composition and vernacular names over time. METHODS: We collected medicinal plants and vernacular names at VOP in August 2018. We identified most plants at the Museo Paraense Emilio Goeldi Herbarium, where we also deposited vouchers and specimen labels. We compared our species composition data to the 1984 inventory by Van den Berg. Furthermore, we investigated the etymologies of the vernacular plant names. RESULTS: We recorded 155 plant specimens and 165 corresponding vernacular names, and collected 146 specimens from the medicinal and ritual stalls of VOP reporting 86 species formerly not recorded at this market. Vernacular names had mostly Portuguese roots, followed by Tupi and African ones. We found 30 species also documented in 1984, and vernacular names that overlapped between both surveys were used for the same botanical species or genus, indicating that vernacular names have changed little in the past decades. Lastly, we found 26 more introduced species sold at VOP compared to 1984. CONCLUSIONS: Forest degradation and deforestation, prevalence of diseases, and methodological factors may play a role in the differences we found in our survey compared to 1984. Of the plants that did overlap between the two surveys, vernacular names of these plants were hardly different. Lastly, the lingual origins of the vernacular names in our survey and the origins of the plant species reflect the history of the intricate syncretism of medicinal plant practices of indigenous, Afro-Brazilian and European origins in Belém.

Marcgrave and Piso's plants for sale: The presence of plant species and names from the Historia Naturalis Brasiliae (1648) in contemporary Brazilian markets.

ETHNOPHARMACOLOGICAL RELEVANCE: Parallelisms between current and historical medicinal practices as described in the seventeenth century treatise Historia Naturalis Brasiliae (HNB) provide us with an overview of traditional plant knowledge transformations. Local markets reflect the actual plant use in urban and rural surroundings, allowing us to trace cross-century similarities of ethnobotanical knowledge. AIMS OF THE STUDY: We aim to verify in how far the HNB, created in seventeenth-century northeastern Brazil, correlates with contemporary plant use in the country by comparing the plant knowledge therein with recent plant market surveys at national level. MATERIALS AND METHODS: We conducted a literature review on ethnobotanical market surveys in Brazil. We used the retrieved data on plant composition and vernacular names, together with our own fieldwork from the Ver-o-Peso market in Belém, to compare each market repertoire with the useful species in the HNB. We analyzed similarities among markets and the HNB with a Detrended Correspondence Analysis and by creating Venn diagrams. We analyzed the methods of the different markets to check whether they influenced our results. RESULTS: Out of the 24 markets reviewed, the greatest similarities with the HNB are seen in northern Brazilian markets, both in plant composition and vernacular names, followed by the northeast. The least overlap is found with markets in the central west and Rio de Janeiro. Most of the shared vernacular names with the HNB belonged to languages of the Tupi linguistic family. CONCLUSION: The similarity patterns in floristic composition among Brazilian markets and the HNB indicate the current wider distribution and trade of the species that Marcgrave and Piso described in 1648 in the northeast. Migration of indigenous groups, environmental changes, globalized and homogenous plant trade, and different market survey methods played a role in these results. The HNB is a reference point in time that captures a moment of colonial cultural transformations.
