  Resembling H. malacophylla. Geerinck (Taxonom. 32: 24, 2011) remarks on specimen Germain 2050 figuring in Fl. Afr. Centr., Orchid. 1: 135, 1984, from Zaire, Bas-Congo, near Kisantu. This specimen was first mixed with H. gabonensis (= H. procera) later renumbered as Germain 2050 bis. The presence of H. amoena in Bas-Congo is improbable and the error seems to be due to a mistake at the mounting of the plant onto the sheet.
