The
type specimen were collected at
Sangabán, Peru.
Peperomia pleiomorpha is a small,
stoloniferous-ascending, epiphytic herb with a
stem 1 mm thick, loosely and minutely pilose. The
leaves on the stolons are round-obovate and minute, while those on the flowering branches are gradually larger and elliptic-ovate to lanceolate, measuring 10–15 mm long and 3–10 mm wide. They are obtuse with a somewhat acute base, minutely appressed-
pubescent, and obscurely
3–5-nerved. The loosely pubescent
petiole is 3–5 mm long. The
spikes are 30 mm long and 1 mm thick, with rather densely inserted flowers, and are borne on a filiform, more or less pubescent
peduncle 5–10 mm long. ==Taxonomy and naming==
