The
type specimen were collected near
Mito, Peru at an altitude of 2700 meters.
Peperomia cerea is a moderately tall, succulent, completely
glabrous herb that hangs from rocks. Its stout
stem is 5 mm thick near the base, becoming more slender upward. The
leaves are opposite, or in whorls of 3–5 on the upper stem. They are rounded-elliptic with rounded ends, about 15 mm long and 10 mm wide, though upper leaves can be more oblong and smaller (barely 10 x 7 mm). The thin margin is more or less revolute. When dry, the leaves have a distinctive waxy-translucent appearance and are
1-nerved. The short
petiole is 1–3 mm long. The
terminal spikes are over 100 mm long and 3–4 mm thick, and are described as being dark red. The
flowers are somewhat loosely inserted on the thick, 15 mm
peduncle. The
ovaries are immersed in the
rachis, acuminate, and have a subapical
stigma. ==Taxonomy and naming==
