Eugenia longipetiolata is a tree up to 15 m high from coastal Atlantic Forest of Brazil, growing in ombrophilous forests from Rio de Janeiro and São Paulo states. This species has leaves with visible, flat gland dots on both faces, black-floccose simple trichomes on abaxial faces, caudate apices, non-cartilaginous margins and a ferruginous-pubescent hypanthium.

The lectotype was chosen for Stenocalyx mutabilis because Berg did not indicate a single specimen and Mattos did not designate a ectotype when he published the nom. nov.. The specimen from M was seen and here considered the lectotype for the name.
