Etlingera maingayi, the Malay rose, is a species of herbaceous, perennial, flowering plant in the ginger family, Zingiberaceae.

[2][3][4] This species occurs in southern Thailand, where its flowers are eaten as vegetables, and Malaysia.

[6] Its leaves are variable, with undulating fringes, and emit a sour scent when crushed.

[5] Leaves of E. maingayi displayed ferrous ion chelating ability and lipid peroxidation inhibition activity that were much higher than young leaves of Camellia sinensis.

The unpleasant sour scent of leaves when crushed may be due to these two acids.
