Six new Eugenia (Myrtaceae) from Amazonas, Brazil

Eugenia breviacuminata, E. campina, E. longa, E. marieensis, E. rhytidocalyx and E. tovomita, all from the northern Brazilian state of Amazonas, are here described and illustrated; E. campina also occurs in the Brazilian state of Para and E. tovomita in Para and Venezuela. Eugenia breviacuminata is morphologically related to E. brownsbergii, but differs by its blades with more lateral veins, calyx lobes in two unequal pairs and more ovules per locule; E. campina is morphologically close to E. tepuiensis, but has shorter petioles, blades shining with the midvein adaxially raised and glabrous pedicels; E. longa is related to E. ramiflora, being distinguished by its markedly narrower blades with thr midvein adaxially impressed and glabrous fruits; E. marieensis resembles E. esteliensis, but differs by its glabrous and narrower blades and larger flowers; E. rhytidocalyx resembles E. quadriovulata, but differs by its smaller blades, pedicellate and pilose flowers; and E. tovomita is possibly related to E. wentii, but differs by its smaller leaves and glabrous yellowish flowers with shorter calyx lobes. Additionally, conservation status are discussed for the species.
