We reveal the enigmatic origin of one of the earliest surviving botanical collections. The 16 th -century Italian En Tibi herbarium is a large, luxurious book with c . 500 dried plants, made in the Renaissance scholarly circles that developed botany as a distinct discipline. Its Latin inscription, translated as “Here for you a smiling garden of everlasting flowers”, suggests that this herbarium was a gift for a patron of the emerging botanical science. We follow an integrative approach that includes a botanical similarity estimation of the En Tibi with contemporary herbaria (Aldrovandi, Cesalpino, “Cibo”, Merini, Estense) and analysis of the book’s watermark, paper, binding, handwriting, Latin inscription and the morphology and DNA of hairs mounted under specimens. Rejecting the previous origin hypothesis (Ferrara, 1542–1544), we show that the En Tibi was made in Bologna around 1558. We attribute the En Tibi herbarium to Francesco Petrollini, a neglected 16 th -century botanist, to whom also belongs, as clarified herein, the controversial “Erbario Cibo” kept in Rome. The En Tibi was probably a work on commission for Petrollini, who provided the plant material for the book. Other people were apparently involved in the compilation and offering of this precious gift to a yet unknown person, possibly the Habsburg Emperor Ferdinand I. The En Tibi herbarium is a Renaissance masterpiece of art and science, representing the quest for truth in herbal medicine and botany. Our multidisciplinary approach can serve as a guideline for deciphering other anonymous herbaria, kept safely “hidden” in treasure rooms of universities, libraries and museums.

The National Herbarium of the Netherlands houses a 17th century, bound herbarium containing 51 dried specimens from Suriname, which was composed by the well‐known botanist Paul Hermann (1646–1695). This is considered as the oldest documented herbarium collection not only for Suriname but for the Guianas region. Most specimens are accompanied by (pre‐Linnaean) Latin or vernacular names and sometimes by Latin descriptions of the plants and their uses. To assess the importance of this collection for the present‐day flora and ethnobotany of Suriname, we identified all specimens (one by using ancient DNA analysis), translated the Latin texts, traced back the origin of the herbarium in national archives, 17th century and modern literature and compared plant names and uses with present‐day ethnobotanical data. We digitized the entire herbarium and made it available online (http://www.hermann‐herbarium.nl). The specimens were probably collected around 1687 by a certain Hendrik Meyer, who had a keen interest in botany and indigenous plant use. The 48 species in the herbarium are almost all useful plants: cultivated crops, wild edible fruits, medicinal plants, timber trees, fish poison, colorants and roof thatch material. Most species are used similarly today, and more than half of the vernacular names still exist in the region. The presence of Abelmoschus esculentus and Sesamum indicum in the herbarium prove the early establishment of African food plants in the emerging plantation economy of Suriname. Unlike Hermann's collections from Ceylon and the Cape, this herbarium was never seen by Linnaeus and therefore does not contain any type specimens.

We present a synopsis of the major trends of Siebold's life, his youth in the Rhineland and his lengthy employment as a physician and natural scientist in the colonial government of the Dutch East Indies. We follow his career on the cramped Japanese island of Dejima where he was based for 6 years. We reveal how, during two visits to Japan, Siebold became a renowned ethnographer, natural historian, author and entrepreneur and an unsuccessful diplomat. In this paper we attempt to provide an insight into Siebold's varied life in Bavaria, The Netherlands and Japan.
