It differs from most Rutaceae taxa by its herbaceous habit and has been treated as a member of the tribe Ruteae. Our study is the first attempt to place Psilopeganum in a phylogenetic context and our results show that the genus belongs to a clade with Boenninghausenia, Ruta and Thamnosma, which are part of Ruteae. Within this group, the position of Psilopeganum remains unclear because the Boenninghausenia-Thamnosma clade, Psilopeganum and Ruta form a trichotomy in most analyses. The ITS dataset placed Psilopeganum as sister to the Mediterranean and Canarian genus Ruta, which is corroborated by morphological similarities. Our studies support that Ruteae is paraphyletic with respect to Aurantioideae and that Dictamnus does not belong to Ruteae. The Indian, Sri Lankan, and Malagasy genus Chloroxylon is sister to the Boenninghausenia-Psilopeganum-Ruta-Thamnosma clade, despite its traditional placement in the subfamily Flindersioideae. The placement of Chloroxylon is consistent with an origin of the group of Chloroxylon, Boenninghausenia, Psilopeganum, Ruta and Thamnosma in southern Asia. The rapid uplifts of the Himalayas could account for one or two vicariance events splitting the lineages of the Boenninghausenia-Psilopeganum-Ruta-Thamnosma clade, and may explain the short branch length and low support for the relationships among Psilopeganum, Ruta, and the Boenninghausenia-Thamnosma clade."],["dc.identifier.doi","10.1111/jse.12208"],["dc.identifier.isi","000383768600007"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/39668"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.publisher","Wiley-blackwell"],["dc.relation.issn","1759-6831"],["dc.relation.issn","1674-4918"],["dc.title","Phylogenetic placement of Psilopeganum, a rare monotypic genus of Rutaceae (the citrus family) endemic to China"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.status","published"],["dspace.entity.type","Publication"]]

These collections play important roles in research and conservation and are integral to our efforts to educate society about biodiversity and conservation. Collections provide an invaluable record of the distribution of organisms throughout the world and through recent and geological time, and they are the only direct documentation of the biological, physical, and cultural diversity of the planet: past, present, and future. Recent developments in bioinformatics and cyberinfrastructure are transforming systematics by opening up new opportunities and as a result major digitization efforts have increasingly made available large amounts of biodiversity data. The collections-based systematics community needs to train the next-generation of systematists with integrative skills, address grand questions about biodiversity at different scales, develop a community-wide cyberinfrastructure, effectively disseminate systematic data to biologists and the public, and proactively educate the public and policy makers on the importance of systematics and collections in the biodiversity crisis of the Anthropocene. Specifically, we call for a new global Biodiversity CyberBank, comparable to GenBank for genetic data, to be the repository of all biodiversity data, as well as a World Organization of Systematic Biology to lead major initiatives of the field.

The phylogenetic analysis sampled about 50% of the 235 accepted species of Melicope as well as representatives of 26 related genera, most notably Acronychia and Euodia. The results based on five plastid and nuclear markers have revealed that Acronychia, Euodia and Melicope are each not monophyletic in their current circumscriptions and that several small genera mainly from Australia and New Caledonia need to be merged with one of the three genera to ensure monophyly at the generic level. The phylogenetic position of the drupaceous Acronychia in relation to Melicope, which has capsular or follicular fruits, remains unclear and Acronychia might be a separate genus or a part of Melicope. The seed coats of Melicope, Acronychia and related genera show adaptations to bird-dispersal, which might be regarded as key innovations for species radiations. Euodia and its relatives, which lack these adaptations, include only about 20 species while the Melicope-Acronychia group consists of about 340 species. The drupaceous genera Comptonella, Dutaillyea, Picrella and Sarcomelicope are nested within Melicope and need to be merged with Melicope.

We present here a detailed molecular phylogenetic analysis of the Hawaiian species of this genus and compare the results with the other genera of Hawaiian Rutaceae, Platydesma and Zanthoxylum. Four nuclear and two plastid markers were sequenced, with the goals of untangling phylogenetic relationships, inferring biogeographic events and comparing patterns of distribution among the three genera. Our results show that there were two colonization events (Melicope + Platydesma, and Zanthoxylum) to the Hawaiian Islands, that Hawaiian Rutaceae have an Asian, Australian or Pacific origin and that there were two independent colonization events of Hawaiian Melicope lineages to the Marquesas Islands. The two most widely distributed Hawaiian Melicope spp. are not monophyletic and the current subgeneric classification of Hawaiian Melicope is highly artificial. On the Hawaiian Islands, Melicope and Zanthoxylum show contrasting biogeographic patterns, suggesting different patterns of dispersal. Melicope has a high percentage of single-island endemics suggesting low dispersal ability, whereas Zanthoxylum taxa tend to occur across multiple islands.
