2. Psidium

Psidium Linnaeus (1753: 406) is the fifth largest genus of Myrtaceae in Brazil with 61 species ( Sobral et al. 2016). It is recognized from other genera of Myrtaceae by the flowers, that are solitary or arranged in short axillary racemes, dichasia or botryoids, pentamerous with a morphologically variable calyx, ranging from cupuliform to distinctly 5- sepaled to closed and calyptrate, rarely appendiculate, and an ovary with 2–5 locules and few to many ovules per locule on a peltate to lamellate intrusive placenta, as well as few to many-seeded fruits, in which the seeds have a bony testa and a C-shaped to cochlear embryo with minute apical cotyledons ( Landrum & Kawasaki 1997, Sobral 2003, Lucas et al. 2011).
