Myrciaria una is a species of plant in the family Myrtaceae. First described in 2019, it is a tree or treelet with blackish fruit, and was previously misidentified as Myrciaria ferruginea.

Etymology
From una, the Tupi word for black, referring to the colour of the fruit.

Description
Myrciaria una is a tree that reaches between 4 and 7m tall. Its leaves are opposite, between 3.5 and 11.5cm long and between 1.3 and 5.1cm wide. The plant produces purplish to blackish fruit up to 20mm in diameter, with up to two seeds.

Distribution
Myrciaria una is endemic to the subcanopy of the atlantic coastal forest in the states of Ceará, Pernambuco, Alagoas and Bahia in north-eastern Brazil.

Conservation status
It has been proposed that Myrciaria una is endangered, due to farming, urban expansion, and the historical fragmentation of the atlantic coastal rainforest in north-eastern Brazil.
