Notes.

It is one of the most distinctive species, either in the field or herbarium sheet. This dainty plant has a long creeping rhizome and well spaced leafy shoots, prominently stiff lateral veins raised on its adaxial lamina, both on living plants and dried specimens.

Scaphochlamys depressa Mas Izzaty, Ampeng & Meekiong is unmistakably the same as Scaphochlamys argentea with its prominent raised lateral veins, broadly elliptic lamina and well spaced leafy shoots. Meekiong (2015) explained that the inflorescence of Scaphochlamys depressa which exerted from the petiole is different from Scaphochlamys argentea where the inflorescence emerges from the base of the petiole. This observation is incorrect as all gingers have terminal inflorescences.
