The Chinese plants named Alpinia chinensis (Retzius) Roscoe in FRPS are referable to A. oblongifolia. They were treated as A. suishaensis by Smith (Edinburgh J. Bot. 47: 63. 1990), who noted that the correct application of the name A. chinensis is uncertain. Moo (in Li et al., Fl. Taiwan 5: 836. 1978) treated A. suishaensis as a synonym of A. oblongifolia.
