Allenanthus
''Allenanthus'' was a genus of flowering plants in the Rubiaceae family but is no longer recognized. It has been sunk into synonymy with ''Machaonia''. ==Taxonomy== ''Allenanthus'' was named by Paul Standley in 1940 in Annals of the Missouri Botanical Garden.〔Standley PC. 1940. ''Allenanthus'' pages 344-346. In: Woodson RE, Schery RW. "Contributions toward a flora of Panama". ''Annals of the Missouri Botanical Garden'' 27(3):265-364.〕 It was named in honor of Paul Hamilton Allen (1911-1963). Until 2004, two species had been recognized, but fieldwork has shown that there is a continuum of variation between them. Comparisons of morphological characters and DNA sequences have shown that ''Allenanthus'' is embedded in ''Machaonia''. This was confirmed by a molecular phylogenetic study of the subfamily Cinchonoideae in 2010.〔 Because of these results, ''Allenanthus'' is no longer maintained as a separate genus.
