Abstract
In a study exploring humus-collecting leaves in drynaroid ferns (Janssen & Schneider 2005), a phylogenetic analysis of this clade was produced, providing evidence that Drynaria (Bory; 1825: 463) Smith (1842: 60) is paraphyletic with regard to Aglaomorpha Schott (1836: pl. 19). Janssen & Schneider (2005) thus proposed to merge Drynaria with Aglaomorpha (the older name) because there are few morphological characters that separate the genera, resulting infrequent confusion. Further studies of the clade found that Christiopteris Copeland (1917: 331) is also included (Schneider et al. 2008), and even though the two species lack nectaries and humus-collecting leaves, they should also be included, which makse the genus more difficult to define morphologically. However, merging these genera is far preferable to disintegration of a well-established genus like Drynaria (Christenhusz & Schneider 2012).
