The
type specimen were collected near
Chanchamayo Valley, Peru at an altitude of 1200 meters.
Peperomia cuprea is a medium-sized, creeping herb with a
stem about 2 mm thick that bears an obscure, evanescent, more or less crisp pubescence. The alternate
leaves are ovate, somewhat acuminate, with a rounded base, and are peltate (attached 3–5 mm above the base). They measure 3.5–4.5 cm long and 2–3.5 cm wide, and are opaque, leathery, with obscure multiple pinnate
nerves and a narrowly revolute margin. The underside is a distinctive copper color and has silky-ciliate hairs. The
petiole is 1–2.5 cm long with a soft, evanescent
pubescence. The
axillary spikes are 55 mm long and 3 mm thick, with tightly arranged
flowers in zones, and are borne on a 2 cm,
glabrous peduncle. The small, round-peltate
bracts are arranged in pseudowhorls of about 20. ==Taxonomy and naming==
