de Candolle mentioned in the protologue (sub a.) a form with subopaque leaves for which he did not assign a name at that time. It was published in 1869 as a distinct variety: Peperomia fernandopoiana var. subopcifolia. Düll (1973: 106) referred erroneously to it as 'Peperomia fernandopoiana var opacifolia, de Candolle 1866'.
