“…The phylogeny of the Menispermaceae is congruent with recent work on the family (e.g. Jacques et al 2011;Wefferling et al 2013), recognizing two subfamilies (Tinosporoideae and Menispermoideae), with the position of Menispermum unresolved. As in past work (e.g.…”

To explore the taxonomic status, phylogenetic patterns, and character evolution of various groups within Papaveraceae s. l. (Pteridophylloideae, Papaveroideae, Hypecoideae, and Fumarioideae), two data sets were created and analyzed using Bayesian inference, maximum likelihood, and parsimony methods: 1) a Ranunculales data set for 82 genera representing all of the major families within the order using three chloroplast DNA regions (atpB, rbcL, and matK) and nuclear 26S ribosomal DNA, and 2) a Papaveraceae s. l. data set for an expanded sampling of the family (27 genera, 40 species) consisting of chloroplast sequences only. Branch support values on the resulting trees derived from the combined data for both the Ranunculales and Papaveraceae s. l. data sets were comparable among the various ranunculalean families and supported subfamilial recognition of Pteridophylloideae, Papaveroideae, Hypecoideae, and Fumarioideae. Within Papaveraceae s. l., most analyses of both data sets resolved the position of Pteridophyllum as sister to all remaining subfamilies and Hypecoum as sister to Fumarioideae; branch support for these relationships varied from excellent to weak. Within Papaveroideae and Fumarioideae, most taxonomic groups previously proposed were recovered, including a well-supported clade of South African species. Optimization of sixteen key morphological characters on the Bayesian inference tree indicated that some characters (e.g. presence of laticifers and nectaries, floral symmetry, spurred petals, and type of androecium) are highly congruent with the molecular phylogeny. Intrafamilial phylogenetic relationships and character evolution of the various taxa within Papaveraceae s. l. are further discussed.

Stephania Loureiro is a large genus within Menispermaceae, with approximately 60 extant species naturally distributed in tropical to subtropical areas in Asia and Africa, and a few in Oceania. This genus possesses highly characteristic endocarps that facilitate identification of extant and fossil specimens. Here, we report some well‐preserved fossil fruits of Stephania from North America and East Asia. The specimens indicate the endocarps were bony or woody with an obovate to obovate‐rotund outline and a horseshoe‐shaped locule. The endocarp length varies from 4.7 to 8.3 mm, and width from 3.7 to 7.0 mm. The endocarp has a clear foramen in the central area and is surrounded by a keel with ribs running along the dorsal surface. Only one lateral crest develops on each side of the endocarp. Two new species are recognized: Stephania wilfii Han & Manchester sp. nov. from the Paleocene to Eocene of Wyoming (USA), and Stephania jacquesii Han & Manchester sp. nov. disjunct between the late Eocene of Oregon (USA) and the late Oligocene of Guangxi Province (China). In addition, on the basis of more detailed morphological comparative analyses, we transfer the fossils formerly treated as Diploclisia auriformis (Hollick) Manchester from the early Eocene of London Clay, and the middle Eocene of Alaska and Oregon to Stephania auriformis (Hollick) Han & Manchester comb. nov. These fossil materials indicate a broader biogeographic distribution for the ancestors of extant Stephania lineages. This finding enhances our knowledge of the taxonomic and morphological diversity of Stephania and provides new evidence concerning its phytogeographic history.

Menispermaceae and the diversification of tropical rainforests near the Cretaceous–Paleogene boundary

Summary Modern tropical rainforests have the highest biodiversity of terrestrial biomes and are restricted to three low‐latitude areas. However, the actual timeframe during which tropical rainforests began to appear on a global scale has been intensely disputed. Here, we used the moonseed family (Menispermaceae), an important physiognomic and structural component of tropical rainforests on a worldwide basis, to obtain new insights into the diversification of this biome. We integrated phylogenetic, biogeographic and molecular dating methods to analyse temporal and spatial patterns of global diversification in Menispermaceae. Importantly, a burst of moonseed diversification occurred in a narrow window of time, which coincides with the Cretaceous–Paleogene (K–Pg) boundary. Our data also suggest multiple independent migrations from a putative ancestral area of Indo‐Malay into other tropical regions. Our data for Menispermaceae suggest that modern tropical rainforests may have appeared almost synchronously throughout the three major tropical land areas close to, or immediately following, the K–Pg mass extinction.
