Eugenia earhartii resembles E. cordata (Sw.) DC. and E. sessiliflora Vahl, however, it differs in a number of significant char- acteristics listed below. Differences between E. earhartii and E. cordata include leaf texture and margins, inflorescence, floral mor- phology, and shape of fruit. The leaves of E. earhartii are rigid-coriaceous, with strongly revolute margins, while those of E. cordata are mostly coriaceous, with plane or revolute margins. The inflorescences in E. earhartii are cauliflorous while those of E. cordata are axillary. In E. earhartii, the flowers are long-pedicellate (4.5-9 mm) and have a hypanthium 5-6 mm wide, while those of E. cordata are sessile and have a hypanthium ca. 1.5 mm wide. Fruits of E. earhartii are globose to oblate, purple, 2-3 cm wide, while those ofE. cordata are ovoid, bright red, 8-10 mm wide.
Eugenia earhartii differs from E. sessili- flora in leaf shape, inflorescence, floral morphology, and color of fruit. It resembles E. sessiliflora in its rigid-coriaceous leaves. Leaves of E. earhartii, however, are ovate to widely elliptic with inconspicuous secondary veins and a cordate base, while those of E. sessiliflora are elliptic with prominent secondary veins and a rounded base. Inflorescences of E. earhartii are strictly cauliflorous while those of E. sessiliflora are axillary as well. The flowers of E. earhartii are pedicellate while those of E. sessiliflora are sessile. Fruits of E. earhartii are purple while those of E. sessiliflora are orange-red
Eugenia earhartii is known only from the southeastern side of the island of Saint John. There is a large population of E. earhartli in deciduous forest to scrubby areas, along the uphill portion of the trail from Europa Bay to White Cliffs. A few more individuals are known to occur along the eastern side of Minna Hill.
