Ocotea guyanensis Aublet, PI. Guiane 4: pl. 310. 1775.
Type. French Guiana, Aublet (possible isotype ? fr. GH).
Meissner recognized three varieties of this widespread species, argentea, sericea, aurea, but I agree with Mez that these should be considered as one species for the distinction in each variety is a minor one. The strict, ascending habit of the leaves, with brightly colored, sericeous under surfaces, sets the species apart without question. Except for these last-mentioned striking leaf-characteristics, O. guianensis is similar to O. glomerata with which complex it is probably most closely associated.
