Very rare in collections, Alocasia alba variegata, which is a variegated variety of Alocasia alba Schott, presents a surprise with its every new leaf . This plant's colouration varies from dark green to lime green to yellow and appears in beautiful splashes on the quilted leaf blades, whose texture is very apparent because of the very prominent secondary venation, which 'divides' the leaves into segments. The rounded, triangular leaf blades grow stout and can achieve very large sizes.
According to Hay (1998), this species can be recognized by some combination of characters including the not-peltate leaves, prominent secondary veins on the abaxial side of leaves, well defined interprimary collective veins, glabrous lower leaf surfaces to petioles, green lower spathe and spathe constriction levelled to sterile interstice. From the other Sumatran species presented in Govaerts et al. (2018), this species can be recognized by its non-peltate leaves and presence of well defined interprimary collective veins (Hay 1998).

The specific epithet is likely due to a mistranslation of one of the original synonyms, Alocasia pallida. In Latin, pallida refers to a yellow-green tint, while in English, pale has come to mean whitish in appearance. This must have been translated into Latin again as alba, white.
