Metric Options: Counts1 Year3 YearSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
Schisandraceae are traditionally subdivided in two genera, Schisandra and Kadsura, based on differences in the organisation of the floral receptacle, the carpels, and the presence or absence of a "pseudostigma". Recently, phylogenetic analyses utilizing ITS sequence data and morphological data resulted in incongruent tree topologies, with the morphological trees suggesting monophyly of the two genera, whereas ITS trees did not resolve Schisandra and Kadsura as monophyletic clades. In the present paper we study seed morphology and leaf epidermal features of 22 species of Schisandraceae in order to provide additional data for a morphological data matrix. Seed morphological characters are highly homoplastic and do not yield further evidence for monophyly of the two genera. Instead, a number of characters appear to support sister group relationships between taxa within the genera, such as, for instance, for K. coccinea and K. scandens, both of which have large seeds along with a multi-layered mesotesta. Considering leaf epidermal characteristics, species of Kadsura were found to be consistently amphistomatic, whereas species of Schisandra are always hypostomatic. Phylogenetic analysis using the extended data matrix resulted in weakly supported Kadsura and Schisandra clades with five and four synapomorphies indicating monophyly of Kadsura and Schisandra, respectively. Fossils ascribed to Schisandraceae date back to the Late Cretaceous. These are tri-and hexacolpate pollen types displaying a combination of features found in modern Schisandraceae and partly also in Illiciaceae. Leaf remains from this period are poorly preserved and difficult to ascribe to Schisandraceae because of the lack of synapomorphies for the family. In the Early Cainozoic, leaf and seed remains from North America and Europe unambiguously belong to the family. Seeds from the Eocene of North America show some similarities to the modern Schisandra glabra from North America, while fossils from Europe show more similarities to modern Asian species. © Springer-Verlag 2005.
