Discussion:

Myrcia laevis Berg, Linnaea 31: 252. 1862, non M. laevis G. Don, 1832

Berg compared this (which he knew only in the fruiting condition), with such species as Myrcia complicata and M . acuminata, i.e., those of the fallax group. Actually the plant he had {Spruce 3502) is an Aulomyrcia in the sense of Berg, closely similar to and hardly distinguishable from Myrcia inaequiloba. It differs from that species in having somewhat more distinctly reddish pubescence (i.e., nearly wanting the gray hairs among the red), in having shorter petioles (1.5-3 or occasionally 5 m m long, as against usuahy 4-6 m m ) , and shorter peduncles (the lowest panicle branches usually 5-10 m m above the base, as against 10-15 or even 20 m m ) . The leaves are lustrous in M . lucida (the lateral veins inconspicuous or even invisible on the upper surface of dried leaves), and the surface is often quite without any raised or impressed lateral veins; the base of the blade is subcordate and broad, and the margins are very shortly if at all decurrent on the petiole; in M . inaequiloba a raised network of lateral veins and connecting veinlets is usually conspicuous, the base of the blade is usuahy narrowed and the margins distinctly decurrent.
