Peperomia aceramarcana is a delicate creeping herb with stout erect branches and a slender stem 1 mm thick, covered with fine short hairs. The leaves are arranged 2–6 at a node, subelliptic and somewhat obtuse at both ends, small at 2 × 7–10 mm, hairless but finely fringed with hairs along the margin, glandular-granular beneath, and very obscurely subpinnately veined. The petiole is scarcely 1 mm long and nearly hairless. The terminal spikes are scarcely 1 mm thick by 25 mm long, grooved, with flowers arranged in loose zones; the peduncle is thread-like, about 10 mm long and covered with fine short hairs. The bracts are round-peltate. The ovary is ovoid, impressed, with a small sharp point (mucronulate), and subapical stigma.^[4]

It was described in 1928 by William Trelease in Bulletin of the Torrey Botanical Club 55, from specimens collected by George Henry Hamilton Tate.^[5] It got its name from the location where the type specimen was collected. ^[4]
