Seed fossil record of Solanaceae revisited
TAXON, Volume 75, Issue 1, Febuary 2026.Abstract The fossil record for Solanaceae has a complex taxonomic history, with many species originally described in the family being subsequently shown to belong in other plant families. In this work, we present an in‐depth analysis of the nightshade seed fossil record, which corresponds to the largest amount of fossil material for the family.

Middle to Late Pleistocene valley‐slope cambering: The interglacial basin at Wing, Rutland, England
Journal of Quaternary Science, Volume 40, Issue 7, Page 1230-1239, October 2025.ABSTRACT A depression in the Jurassic bedrock at Wing, Rutland (eastern England), is infilled by deposits spanning the Late Wolstonian (=Late Saalian) to Early Devensian (=Early Weichselian) substages, including the most complete Ipswichian Stage (=Eemian Stage; ~Marine Isotope Stage 5e) sequence known in Britain. This sequence forms an enclosed pocket,

Typification and current status of the Turkish taxa described by Hanna Czeczott
TAXON, Volume 74, Issue 5, Page 1248-1261, October 2025.Abstract Hanna Czeczott's 1925 expeditions to northern Turkey resulted in the description of 22 new taxa. Our study revisits them using Czeczott's original publications and herbarium collections. Of the 22 taxa described, we located all or parts of the original material for 21, designate 13 lectotypes (including one second‐step) and confirm 7 holotypes,
