Peperomia arborigaudens is a creeping, pendent epiphyte with slender, elongated stems covered in short, soft hairs. The leaves are alternate, ovate, and acuminate, with a very short and obscure peltate attachment. The leaf base is rounded to nearly truncate, and each blade measures 4 to 5.5 cm in length and 3 to 4 cm in width, with five to seven nerves. Young leaves are tomentulose on the underside, becoming sparsely pilose and glandular-granulose with age. When dried, the leaves are thin and take on a more or less rosy hue. The petioles are 3 to 5 mm long and loosely villous. The flower spikes are terminal and slender, reaching 90 mm in length, borne on a filiform, somewhat villous peduncle 2 cm long. The floral bracts are minute, rounded, and peltate.
