Discussion:

Aulomyrcia cuprea Berg, Mart. Fl. Bras. 14(l): 77. 1857.

Aulomyrcia chrysophylla Berg, Mart. Fl. Bras. 14(1): 125. 1857

Apparently not yet known from the Guianas, this species ranges from Amapa to Maranhao. It must be a conspicuous plant in nature because of the silky red-golden hairs that cover the young herbage and the inflorescence. It is easily recognized in the herbarium because of the characteristic pubescence and the trilocular ovary. Berg distinguished Aulomyrcia cuprea from A. chrysophylla chiefly on the basis of the supposedly bilocular ovary of the former; the other differences between the two supposed species are insignificant. Examination of several buds from the type of A. cuprea shows that the ovary is consistently trilocular, as in the type of A. chrysophylla, and in all modern specimens I have seen. Evidently Berg erred in describing it as bilocular, perhaps because the specimens are in young bud and the structure of the ovary correspondingly difficult to make out. Kiaerskou, in transferring the name Aulomyrcia cuprea to Myrcia, supposed that he had discovered (among specimens collected by Glaziou) a 3-locular form of a species with bilocular ovary!
