Peperomia maguirei has some resemblance to P. quadrangularis but differs in having mostly obovate leaves that are slightly emarginate (with hairs in the indentation) vs. usually broadly elliptic leaves with continuous apex. The leaves in P. maguirei are in whorls of 1-4, whereas in P. quadrangularis they are strictly opposite. The fruits of the latter are sunken in the rachis, which is distinctly ridged (at least when dried), whereas the fruits of P. maguirei are not sunken and the rachis is not obviously ridged.
