Revision of Tinospora (Menispermaceae - Chasmantheroideae - Burasaieae) in Singapore.
The lianescent genus Tinospora Miers in Singapore is revised. Four species are recognised, two of which are newly described. Tinospora krispura I.M.Turner sp. nov. is known from Christmas Island and Singapore. Tinospora singapura I.M.Turner sp. nov. is known only from Singapore. Two new lectotypifications are included, one at the second...Turner, I. M.

Online tree expansion could help solve the problem of scalability in Bayesian phylogenetics.
Bayesian phylogenetics is now facing a critical point. Over the last 20 years, Bayesian methods have reshaped phylogenetic inference and gained widespread popularity due to their high accuracy, the ability to quantify the uncertainty of inferences and the possibility of accommodating multiple aspects of evolutionary processes in the models that...Truszkowski, Jakub ; Perrigo, Allison ; Broman, David ; Ronquist, Fredrik ; Antonelli, Alexandre

Widespread Support for a Global Species List with a Formal Governance System.
Taxonomic data are a scientific common. Unlike nomenclature, which has strong governance institutions, there are currently no generally accepted governance institutions for the compilation of taxonomic data into an accepted global list. This gap results in challenges for conservation, ecological research, policymaking, international trade, and other areas of scientific and...Lien, Aaron M. ; Banki, Olaf ; Barik, Saroj K. ; Buckeridge, John S. ; Christidis, Les …

Evolution of pollen grain morphology in Amorimia and allies evidences the importance of palynological apomorphies and homoplasies in Malpighiaceae systematics.
– Pollen grain morphology is an important morphological character for aiding the systematics of flowering plants. For Malpighiaceae, only a single unpublished palynological study has comprehensively sampled ca 60 of this family’s 75 currently accepted genera. To test the systematic relevance of pollen morphology in and allies, we characterised the... -

Domestication of the Amazonian fruit tree cupuaçu may have stretched over the past 8000 years.
Amazonia, one of the largest and most biodiverse ecosystems on Earth, is a significant yet less-known arena for ancient plant domestication. Here, we traced the origins of ( ), an Amazonian tree crop closely related to cacao ( ), cherished for its flavorful seed-pulp, by employing an extensive genomic analysis... -

Myrcianthes (Myrtaceae) revisited: a new species, a new synonym, a lectotypification and an overview of its wood anatomy.
Myrcianthes is a New World genus of Myrtaceae (Tribe Myrteae) with 38 currently accepted species that was monographed in 1992. This paper proposes a new species, Myrcianthes cruciata from Northeastern Brazil (Bahia, Ceará and Sergipe), the synonymization of M. cavalcantei under M. fragrans and the lectotypification of the former name.... -

Ardisia krauensis, a new species of Primulaceae (Myrsinoideae) from Peninsular Malaysia.
Ardisia krauensis, a new species of Primulaceae from Peninsular Malaysia, is described and illustrated. The new species is assignable into subgenus (§) on account of specialised lateral reproductive branches bearing a terminal inflorescence subtended by foliose bracts. Morphologically, the new species mostly resembles in having elliptic leaves. However, the new... -

Molecular phylogenetics of Maranta (Marantaceae: Zingiberales): non-monophyly and support for a wider circumscription.
Neotropical Maranta has repeatedly emerged as non-monophyletic in molecular phylogenetic studies, but no taxonomic changes have been proposed due to previous weak support for the main clades and overall sparse taxonomic sampling. Our study includes a phylogenetic hypothesis strictly based on molecular evidence, using nuclear ribosomal (nrITS) and plastid (rps16,... -

Do Ectomycorrhizal Trees Select Ectomycorrhizal Fungi That Enhance Phosphorus Uptake under Nitrogen Enrichment?
Globally, forests are impacted by atmospheric nitrogen (N) deposition, affecting their structure and functioning above and below ground. All trees form mutualistic root symbioses with mycorrhizal fungi. Of the two kinds of mycorrhizal symbioses of trees, the ectomycorrhizal (EcM) symbiosis is much more sensitive to N enrichment than the arbuscular...Kuyper, Thomas W. ; Suz, Laura M.

Morphological Continua Make Poor Species: Genus-Wide Morphometric Survey of the European Bee Orchids (Ophrys L.).

The lower figure of nine macrospecies is based primarily on seeking small but reliable discontinuities in DNA ‘barcode’ regions, an approach... -

Intra-Specific Variation in Desiccation Tolerance of Citrus sinensis ‘bingtangcheng’ (L.) Seeds under Different Environmental Conditions in China.
Intra-specific variation in seed storage behaviour observed in several species has been related to different maternal environments.

We chose Citrus sinensis ‘bingtangcheng’ for the present study due to its known variability in desiccation... -
