This study analyses the pollination systems and biogeography of three allopatric species of Schisandra (Section Euschisandra) consisting of S. glabra (North America), S. bicolor (China), and S. repanda (Japan); the clade is delimited in a phylogeneti

The fi rst three branches of the angiosperm phylogenetic tree consist of eight families with ~201 species of plants (the ANITA grade). The oldest fl ower fossil for the group is dated to the Early Cretaceous (115 - 125 Mya) and identifi ed to the Nym

The plants of Kadsura longipedunculata (Schisandraceae) are monoecious and possess either red or yellow male flowers (the androecium), with yellow tepals, and yellow female flowers. All flower types simultaneously produce heat and floral odours (domi

† Background and Aims The mutualistic interaction between insects and flowers is considered to be a major factor in the early evolution of flowering plants. The Schisandraceae were, until now, the only family in the ANITA group lacking information

Sequences of nuclear ribosomal DNA ITS and chloroplast trnL‐F regions were used to construct a phylogeny of Schisandraceae. The results show that there are two major clades in Schisandraceae. One is composed entirely of Schisandra species; the othe

Ipomoea pescaprae (L.) Roth (railroad vine, Convolvulaceae) is a pantropical, perennial beach plant that forms large patches just above the high tide line on coastal beaches and dunes throughout tropical and subtropical areas of the world. In spite o

Illicium floridanum, a species belonging to the basal extant angiosperm taxon Illiciaceae, reportedly exhibits self-incompatibility (SI). To date, the site and timing of SI within the carpel of this species remains unidentified. Thus, the objective o

The boreotropical flora concept suggests that relictual tropical disjunctions between Asia and the Americas are a result of the expansion of the circumboreal tropical flora from the middle to the close of the Eocene. Subsequently, temperate species d

Coleoptera and Diptera are the primary pollinators of extant basal angiosperms (wind pollination is rare); lineages of these insects were established by the Late Jurassic. Contemporary examples of insect pollination of nonangiosperm plants are presen

The role and chemical composition of soral scent in pollination systems of angiosperms has been largely ignored because of the difÞculty in characterizing scent components. Magnoliaceae is one of the few plant families in which the soral scents of a
