摘要
The history of classification of the tribe Bignonieae and its genera are reviewed as context for a comprehensive new genus-level classification of the tribe Bignonieae (Bignoniaceae, Lamiales). This new classification is based on a well-supported phylogeny based on multiple molecular markers from both chloroplast and nuclear DNA, a morphological survey, and a broad sampling of taxa. Genera are circumscribed here as clades that are well supported as monophyletic by molecular data and also recognizable by one or more morphological synapomorphies. Perianthomega Bureau ex Baill, is here transferred from Bignoniaceae tribe Tecomeae into Bignonieae, and 21 genera and a total of 393 species are recognized in Bignonieae: Adenocalymma Mart. ex Meisn. (82 species), Amphdophium Kunth (47), Anemopaegma Mart. ex Meisn. (45), Bignonia L. (28), Callichlamys Miq. (1), Cuspidaria DC. (19), Dolichartdra Cham. (8), Fridericia Mart. (67), Lundia DC. (13), Manaosella J. C. Gomes (1), Mansoa DC. (12), Martine Ila Bail. (2), Neojobertia Bail. (2), Pachyptera DC. ex Meisn. (4), Perianthomega (1), Pleonotoma Miers (17), Pyrostegia C. Pres]. (2), Stizophyllum Miers (3), Tanaedium Sw. (17), Tynanthus Miers (15), and Xylophragma Sprague (7). Several genera are here circumscribed differently from previous classifications, in particular Memora Miers and Sampaiella J. C. Gomes are synonymized with Adenocalymma; Distictella Kuntze, Distictis Mart. ex Meisn., Glaziova Bureau, Pithecoctenium Mart. ex DC., and Urbanolophium Melch. are synonymized with Amphdophium; Cydista Miers, Clytostoma Miers ex Bureau, Macranthisiphon Bureau ex K. Schum., Mussatia Bureau ex Bail, Phryganocydia Mart. ex Bureau, Potamoganos Sandwith, Roentgenia Urb., and Switaea Dugand are synonymized with Bignonia; Macfadyena A. DC., Melloa Bureau, and Parabignonia Bureau ex K. Schum. are synonymized with Dolichandra; Arrabidaea DC. is synonymized with Fridericia; Gardnerodoxa Sandwith is syrionymized with Neojobertia; Leucocalantha Barb. Rodr. is synonymized with Pachyptera; and Ceratophytum Pittier, Periarrabidaea A. Samp., Paragonia Bureau, Pseudocatalpa A. H. Gentry, and Spathicalyx J. C. Gomes are synonymized with Tanaecium. The genera Adenocalymma, Amphilophium, Fridericia, Dolichandra, and Tanaecium are formally emended here as to diagnosis and circumscription. A natural key, complete morphological descriptions, and illustrations characterize the accepted genera, and full generic synonymy and a catalogue of their component species summarize their basic nomenclature and geographic range. Three new names are published: B. neouliginosa L. G. Lohmann replaces Phryganocydia uliginosa Dugand; B. neoheterophylla L. G. Lohmann replaces Cydista heterophylla Seibert; and Tanaecium neobrasdiense L. G. Lohmann replaces Sanhdaria brasdiensis Bail. Thirty-two generic names are newly synonymized, and 144 new nomenclatural combinations are made. A lectotype is designated for one genus, Perian-abidaea A. Samp., and 78 species names. One species name is neotypified, Memora campicola Pi lg. Adenocalymma campicola (Pi lg.) L. G. Lohmann).
