An overview of lardizabalaceae.
This overview provides a taxonomic revision of the family Lardizabalaceae. Seven genera are accepted here (Akebia, Boquila, Decaisnea, Lardizabala, Sargentodoxa, Sinofranchetia and Stauntonia); as a result of molecular and morphological data Archakebia is included in Akebia and Holboellia and Parvatia are united with Stauntonia. The number of species in the family is increased to 40, resulting from elevation of some varietal and subspecific names to species level, although it should be noted that the differences between species of Stauntonia are often minute, both morphologically and genetically, and may not warrant recognition. To facilitate identification, keys to the genera and species are provided and taxonomic discussions are given. Horticultural information and illustrations are provided for every genus.
