Peperomia chalhuapuquiana is a moderately small, erect, and divaricately branched herb with many branches. The stems are 2âÂÂ3 mm thick and covered in crisp pubescence. The alternate leaves are ovate to elliptic-ovate, with a bluntly subacuminate tip and a mostly rounded base. They measure 2âÂÂ4 cm long and 1.5âÂÂ2.5 cm wide, with ciliate margins.

The spikes are terminal and from the upper axils, reaching 100 mm in length and 2 mm in thickness. The flowers are inserted somewhat loosely, sometimes appearing whorled, and the spike is borne on a slender, glabrous peduncle barely 10 mm long. The berries are subglobose, mucronate, turn black when dry, and have an oblique stigma.
