by Alessandro Oliveira Souza, Marcos José da Silva, Gwilym Peter Lewis, Mariana Pires Campos Telles, Chamaecrista is a monophyletic genus, but most of its infrageneric categories have been shown to be paraphyletic, including series Rigidulae which currently comprises 30 species, all endemic to Brazil and most occurring in the cerrado vegetation of the central highlands of the country. This molecular phylogenetic study tests the monophyly of Chamaecrista series Rigidulae based

Litvinskaya, Eleonora Gabrielian, Thomas Borsch, Eckhard von Raab-Straube Jurinea (Asteraceae, Cardueae) is a large Eurasian genus of about 180 species with centers of diversity in Central and Southwest Asia and the eastern Mediterranean. The genus includes many species with adaptations to xero- and chasmophytic habitats and comprises numerous endemics, especially in
by Dmitry Sokoloff, Isabel Marques, Terry Macfarlane, Margarita Remizowa, Vivienne Lam, Jaume Pellicer, Oriane Hidalgo, Paula Rudall, Sean Graham The flora of the southwestern Australian biodiversity hotspot is rich in endemic species, many of which remain to be discovered or properly described; estimates of species diversity and levels of endemism should take into account the possible occurrence of cryptic species. Here we explore taxonomic diversity in a Western Australian
by Jose Maria Gabriel Y. Galan, Sonia Molino, Emily B. Sessa, Pawel Wasowicz The family Blechnaceae is a moderately sized leptosporangiate fern lineage, with 24 genera and around 250 species. Struthiopteris accommodates small to medium sized, dimorphic, pinnate species. It is composed of six northern species: S. spicant is distributed in western parts of Europe and North America; S. fallax is endemic to Iceland; S. niponica, S. amabilis and S. castanea are endemic to Japan, a
by Hang Sun, Zhuo Zhou, Jin-Jin Hu, Jun Wen Pyrularia is a small parasitic genus of the Santalales with two to five species exhibiting a well-known classical intercontinental disjunct distribution between eastern Asia (EA) and eastern North America (ENA). Pyrularia and another santalaceous genus Buckleya represent the only two parasitic plant lineages with the EA–ENA disjunction. The present study was carried out to assess the species number, and molecular and morphological d
by Gabriel Damasco, Douglas Charles de Burgh Daly, Alberto Vicentini, Paul Van Antwerp Fine Species delimitation remains a challenge worldwide, but especially in biodiversity hotspots such as the Amazon. Here, we use an integrative taxonomic approach that combines data from morphology, phylogenomics, and leaf spectroscopy to clarify the species limits within the Protium heptaphyllum species complex, which includes subsp. cordatum, subsp. heptaphyllum, and subsp. ulei. A molec
by Sylvain Razafimandimbison, Catarina Rydin Circumscriptions of the Australasian tribes Ophiorrhizeae and Pomazoteae (Rubiaceae) as well as their generic relationships and limits have long remained unsettled. These tribes were originally delimited by Bremekamp based on the lack of raphides and testa cell patterns (thick- versus thin-walled testa cells, respectively). Some authors have synonymized the two or treated Pomazoteae as a synonym of other tribes despite the fact tha
by Pablo Ferrer Gallego The lectotypification of four Linnaean names in the genus Juncus: J. articulatus, J. inflexus, J. pilosus (≡ Luzula pilosa) and J. stygius is discussed. The designation of the nomenclatural types is based on the consultation of Linnaeus’s original material and the literature cited in the respective protologues. The names are lectotypified using specimens from LINN and UPS (Burser’s collection) herbaria, and a Morison’s illustration (1699) for the name
by Duilio Iamonico, Romeo Di Pietro The typification of the names Valeriana celtica, V. saxatilis and V. sibirica is discussed. Specimens from the UPS, and an illustration by Amman are designated as the lectotypes.
