Sci. 2 C: 410. 1907 . Range: — Nicaragua to Panama , Colombia to Bolivia (CO, LP) and western Brazil . Ecology: —Rare; terrestrial in humid forests; 550–17000 m . Notes: —This genus and species are mired in a taxonomic and nomenclatural conundrum. The type of Aspidium draconopterum (and hence the type of Draconopteris ), from Colombia , is in fact a Hypoderris , a fact not realized when Draconopteris was described. The two specimens sequenced by Zhang et al . (2016) , and the basis for naming the genus Draconopteris as separate from both Hypoderris and Tectaria , are now believed to be referable to the species heretofore called Tectaria myriosora (Christ) C.Chr. , usually treated as a synonym of Tectaria draconoptera (D.C.Eaton) Copel. by recent authorities (e.g., Moran 1995 ). The upshot of this is that Draconopteris is a later synonym of Hypoderris , and “ Draconopteris ”, sensu Zhang et al. (2016) has no name. The species epithet “ draconoptera ” no longer applies to the intended taxon, which would take (under some new generic name) the epithet “ myriosorum ” , based on Aspidium myriosorum Christ , a heterotypic synonym of “ Draconopteris draconoptera .” Aspidium draconopterum D.C.Eaton (1860) has priority over Polypodium nicotianifolium Baker (1868) , so Hypoderris nicotianifolia would become H. draconoptera (D.C.Eaton) comb. ined. To remedy this nomenclatural “musical chairs” and avoid ensuing taxonomic confusion, Draconopteris must be conserved with a different type , a solution currently being investigated by C. Rothfels et al. (2018).
