The
type specimen were collected near
San Roque, Peru, at an altitude of .
Peperomia elegantifolia is a medium-sized,
glabrous, forest-dwelling herb. The alternate
leaves are lanceolate to typically lanceolate-obovate, somewhat acute, with a cuneate base, measuring long and wide. They are
pinnately nerved from the lower half. The
petiole is barely 1 cm long. The spikes are borne in pairs in the axils on slender peduncles. The branching structure is complex: a main
peduncle about 3 cm long may bear the spikes, or a longer peduncle may terminate in a reduced leaf and then the
spikes. The ultimate peduncles bearing the spikes are 5–10 mm long. ==Taxonomy and naming==
