Two subspecies of Pereskia grandifolia are recognized. Subspecies grandifolia has receptacular bracts that are green and rarely recurved, sepal-like perianth parts that are green to pink, pink petal-like perianth parts that are 1.5-3.3 cm

Subspecies violacea differs in having receptacular bracts that are purplish pink to dark purple and recurved, sepal-like perianth parts that are purplish pink to dark purple, pink petallike perianth parts that are 1-1.8 cm (0.4-0.7 in) long, and pale yellow anthers; it occurs in the transition zone of forest and savanna at elevations of 600-1400 m (2000-4600 ft) in Espirito Santo and Minas Gerais.
