C.V.Morton, Contr. U.S. Natl. Herb. 38: 41. 1967. Range: —Amazonian Peru , Brazil , and Bolivia (BE). Ecology: —Rare, known from a single Bolivian collection: Weigelt 90373 (LPB, TUR, UC, Z); terrestrial in humid forests, collected on steep seepage slope near stream; 250 m , to 900 m elsewhere. Notes: —Preliminary, unpublished molecular data suggest that this species may not, in fact, be a Diplazium , but rather belongs to the Aspleniaceae (H. Schneider, pers. comm; W. Testo, pers. comm.), which, with the addition of Desmophlebium and Hemidictyum , already includes two distinct, phylogenetically basal genera with areolate veins ( Kessler & Smith 2017 b).
