Peperomia pertomentella is a rather large, diffuse, terrestrial, sparsely branched herb with a rust-colored tomentulose indumentum. The alternate leaves are ovate, more or less acuminate, with a rounded to subcordulate base, measuring 4âÂÂ6 cm long and 2.5âÂÂ4 cm wide. They have obscure pinnate venation and, when dry, are brown and leathery. The petiole is 1âÂÂ2 cm long. The sympodial spikes, one or two, terminate a 1 cm long, 2-bracteate branchlet. They are 90âÂÂ100 mm long and 1 mm thick, with a peduncle 10âÂÂ15 mm long. The berries are oblong, narrowed at the apex, and bear a small shield (scutulum), with a central stigma.
