Peperomia plicatifolia is a somewhat small, glabrous,
stoloniferous-ascending herb with a slender
stem. The alternate
leaves are lanceolate to lanceolate-oblong, somewhat acute at both ends, measuring 15 mm long and 4–5 mm wide. They are
pinnately nerved from the lower part, typically plicate, leathery, and yellowish. The
petiole is very short. The terminal
spikes are 30 mm long and 1 mm thick, with a
peduncle 10 mm long. The
berries are pear-shaped, curved, and stalked, with a subapical
stigma. ==Taxonomy and naming==
