Earlier studies indicated that the genus Nectandra, currently the second-largest genus of the Neotropical Lauraceae, might be diphyletic in its traditional circumscription, but the evidence was not quite conclusive. Our phylogenetic analyses based on nuclear (ITS) and chloroplast (psbA-trnH) sequences of 45 Nectandra species as well as 42 representatives of 18 genera of the core Lauraceae (Ocotea complex, Laureae, Aiouea, Asian Cinnamomum and Persea groups) confirm the suspicion that Nectandra is diphyletic. The two groups, Nectandra s.str. and the N. coriacea group, are each well supported in the maximum parsimony and Bayesian analyses, but they are not sister to each other. Nectandra s.str. is sister to Pleurothyrium, and the clade including Nectandra s.str. and Pleurothyrium is very likely closer to the dioecious taxa of the Ocotea complex. The N. coriacea group, on the other hand, appears to be closer to bisexual taxa known as the Ocotea helicterifolia group. In addition, Nectandra s.str. is characterized by a large deletion in the psbA-trnH spacer compared to all other core Lauraceae, including its sister group Pleurothyrium. Considering these facts, Nectandra cannot be maintained in the traditional sense. We therefore transfer the species of the N. coriacea group to the oldest generic name applied to this group, Damburneya . On the basis of fossil records from the American subcontinents and in accordance with previous phylogenetic and molecular clock studies we suggest a scenario of a climate-driven migration from North to South America, with a subsequent rapid radiation of Nectandra s.str. in South America.

Abstract. This study refers to specimens of Lauraceae collected in Brazil by Carl Friedrich Philipp von Martius between 1817 and 1820. He collected 57 currently accepted species of Lauraceae, which belong to nine genera: Aniba, Cassytha, Cinnamomum, Cryptocarya, Dicypellium, Licaria, Nectandra, Ocotea, and Persea, for which Martius is known to have made about 99 different collections. The vast majority of them are nomenclatural types and, taking into account the synonyms involved, encompassing 26 holotypes, 23 lectotypes, and 30 syntypes. Besides Martius himself, early descriptions and citations of these materials were made by Nees von Esenbeck, Meissner, and Mez, the first monographers of the family. Martius’s collections were the basis for the Flora Brasiliensis, where the taxonomic treatment of Lauraceae was made by the Swiss botanist Carl Daniel Friedrich Meissner in 1866, being of particular interest for indicating all the collections examined and available at that time. Here, we provide an annotated and updated list of 60 entries with information on the status of the names and their types, currently accepted names, collections found in different herbaria, accompanied by an Index to Scientific names and an Index to Collections. Although there are no cases of specimens of Lauraceae collected by Martius from his “Martii Herbarium Florae Brasiliensis,” they are also listed here since they have been attributed to him in literature. Lectotypes for two names, Cryptocarya speciosa, and Nectandra nitidula var. maior, are designated, and a new synonymy is proposed.
