title: A taxonomic revision of Neodietrichia (Araneae: Linyphiidae), a rarely encountered but widespread spider taxon

description: This dataset contains the digitized treatments in Plazi based on the original journal article Milne, Marc A., O’Neil, Caylie, Bertaux, James (2023): A taxonomic revision of Neodietrichia (Araneae: Linyphiidae), a rarely encountered but widespread spider taxon. Zootaxa 5296 (1): 31-44, DOI: 10.11646/zootaxa.5296.1.3, URL: http://dx.doi.org/10.11646/zootaxa.5296.1.3AbstractThe linyphiid spider Dietrichia hesperia was described from California in 1933 by Crosby and Bishop. The genus was renamed to Neodietrichia in 2008 by Özdikmen since Dietrichia was already occupied by a fossil bivalve. Until now, this rarely collected arboreal spider was the sole member of Neodietrichia. Herein we revise the genus by redescribing Neodietrichia hesperia (Crosby and Bishop, 1933), transferring Lophomma depressum (Emerton, 1882) to Neodietrichia as Neodietrichia depressum n. comb., and provide the first description of the female of this species.

description: This dataset contains the digitized treatments in Plazi based on the original journal article Yang, Feng, Wang, Huan-Chong (2025): Taxonomic clarification of Silene dawoensis (Caryophyllaceae): synonymization with S. batangensis and reinstatement of S. longiuscula. PhytoKeys 257: 51-64, DOI: 10.3897/phytokeys.257.153202AbstractBased on a comprehensive analysis of type materials, protologues, herbarium specimens, and field observations, this study clarifies the taxonomic status of Silene dawoensis and related species in China. Our findings reveal that S. dawoensis shares key similarities with S. batangensis, including leaf shape, inflorescence type, and calyx structure, and therefore we have placed S. dawoensis as a synonym of S. batangensis. Additionally, specimens historically misidentified as S. dawoensis are reassigned to S. markamensis, a species previously overlooked in regional floras. Concurrently, based on diagnostic differences in leaf shape, calyx length, and petal morphology, we reinstate S. longiuscula as a distinct species, previously treated as a synonym of S. dawoensis. Typification for S. batangensis and S. dawoensis is given. Descriptions, distribution maps, taxonomic notes, and morphological comparison table are provided for these three species.

title: Critical review of the nomenclature and taxonomy of Sorghastrum canescens (Poaceae: Panicoideae: Andropogoneae), an endemic Brazilian species

description: This dataset contains the digitized treatments in Plazi based on the original journal article Maciel, Jefferson Rodrigues, Proença, Carolyn Elinore Barnes, Valls, José Francisco Montenegro, Oliveira, Regina Célia De (2021): Critical review of the nomenclature and taxonomy of Sorghastrum canescens (Poaceae: Panicoideae: Andropogoneae), an endemic Brazilian species. Phytotaxa 511 (1): 37-50, DOI: 10.11646/phytotaxa.511.1.3, URL: http://dx.doi.org/10.11646/phytotaxa.511.1.3AbstractSome taxonomic groups impose the need to use continuous morphological characteristics in taxon delimitation, and the grass genus Sorghastrum is a clear case of this necessity. Sorghastrum canescens was described based on the length of its awns. However, insufficient and scattered sampling has obscured the identity of this species for at least 137 years, while it was considered synonym of S. incompletum var. incompletum. In this study we evaluate statistical differences in the original and current morphological concepts of S. canescens using analysis of variance and posterior pairwise comparison of means and medians. We also retrieved the nomenclatural history of the binomial S. canescens to clarify possible errors in the synonymization of this species. All the statistical evidence refutes the hypothesis that S. canescens is a synonym of S. incompletum var. incompletum. Historical data revealed an error in the identification of the correct basionym of S. canescens and this error has been repeated in several taxonomic revisions. We were also able to establish an approximate date for the type-collection of S. canescens. We therefore propose the reestablishment of the name Sorghastrum canescens and provide morphological descriptions and illustration of this species.
