= Myrcia daphnoides De Candolle var. nervosa Kiaerskou ex Glaziou, Mém. Soc. Bot. France 3: 218 (1908), nom. nud. Specimens examined:— BRAZIL. Goiás: Glaziou 21169 (G!, K000342778 !, P00547346!, P00547345!).

Specimens examined:— BRAZIL. Goiás: Glaziou 21144 (BR!, P00545103!, P00545104!); Glaziou 21169 (BR!), Glaziou 21170 (BR!, K000344854!, K000344853!, P00553656!, P00553657!), Glaziou 21189 (K000344782!, K000342635!, P00545106!, P00545105!)

The specimens cited here as Myrcia guianensis are locally well-known morphotypes of this species complex, with glabrous (or almost) branches, obconic buds and a trilocular ovary. Some were erroneously identified as Myrcia bombycina (O. Berg 1857 –1859: 66) Niedenzu (1893: 75) (Glaziou 21144 and 21189) and M. daphnoides De Candolle (1828: 246) (Glaziou 21169). The strangest morphotype he collected is Glaziou 21170, incorrectly identified as M. virgata Cambessèdes 1832: 320 ). This morphotype was previously known as M. decrescens (O. Berg 1857 –1859: 135) Mattos (2008: 126), but is now a M. guianensis synonym and unusual to those not used to the Goiás flora. Myrcia virgata is a very different species that only occurs in the Serra Dourada. Myrcia guianensis was collected four times in the Distrito Federal (Lagoa Mestre D’Armas, Guariroba, Chapadinha and Rio Gama) and once in Goiás (Rio Areias).
