Peperomia pubescentinervis is a rather large but delicate, branching herb with a stem 1âÂÂ2 mm thick above, bearing a transient, sparse, soft pubescence. The leaves are typically in whorls of 3. They are lanceolate-ovate, acutely acuminate, with a generally acute base, measuring 4âÂÂ7 cm long and 2âÂÂ3 cm wide, and are 5-nerved with the nerves confluent for about 5 mm at the base. When dry, they are thin, green, and shiny, with pubescence along the nerves above, and are paler and more or less punctate beneath. The terminal and axillary spikes are filiform, 60 mm long, with somewhat loosely arranged flowers, and are borne on a very delicate peduncle 15âÂÂ20 mm long.
It was described in 1936 by William Trelease in ', from specimens collected by Frank Lincoln Stevens.
The epithet combines the Latin pubescens and nervis, referring to the pubescence present along the leaf veins.
It is native to Peru. It grows as a terrestrial or epiphytic herb. It grows on wet tropical biomes.
This species is assessed as Threatened, in a preliminary report.
