The type specimen were collected at Pampalca, Peru at an altitude of 3200 meters above sea level. Peperomia pampalcana is a tall, forked or divaricately branched, succulent herb with a stem 3–5 mm thick, sparsely covered in stiff villous hairs. The leaves are opposite or rarely in whorls of 3. They are elliptic to round-ovate, bluntly short-acuminate, with a rounded to somewhat acute base, measuring about 4 cm long and 3.5 cm wide. Upper leaves are smaller (1.5 cm long, 1 cm wide), and on the ultimate flowering branchlets, they are reduced to 8 mm long and 5 mm wide. The leaves are 3-nerved (or 5-nerved on longer ones), firm when dry, brown above, yellowish beneath, and loosely villous. The petiole is about 1 cm long, much shorter on reduced leaves. The spikes are solitary in the axils of reduced leaves and also terminal on short branchlets, appearing somewhat paniculate. They are 40–60 mm long and 3 mm thick, with a sparsely pilose peduncle 10–15 mm long. The berries are ovoid, pointed, and bear a pseudocupula, with an apical stigma.
