Two specimens were cited by Glaziou (1908: 220) as Myrcia paracatuensis var. pumila: Glaziou 21131 and Glaziou 21132; the first is cited under M. pinifolia . The collections Glaziou 21133, 21134, 21136 and Glaziou s.n. were identified as Myrcia paracatuensis var. paracatuensis , and Glaziou 21162 and 21163 as M. rorida var. rorida . Some labels cite these specimens as “ Myrcia pumila ” and “ M. microphylla ”. The easiest way to recognize this species is by its glabrescent branches with relatively small, elliptic to linear leaves. Myrcia myrtillifolia is very common in high altitude campo rupestre in Goiás and Minas Gerais. This species was collected in many localities in Goiás (Serra dos Cristaes, Capelinha du S. Antonio, Serra Dourada and Pyreneos) and in two localities in the Distrito Federal.
