This work analyses and describes seed and embryo morphology of eight Poecilanthe species. Poecilanthe species can be divided in four groups based on seed and embryo characters: (1) P. amazonica-type has overgrown seeds, bears cataphylls on the epicotyl and has an inflexed hypocotyls-root axis; (2) P. effusa-type has two types of trichomes on the epicotyl, which is longer than the hypocotyls-root axis; (3) P. parvilora-type has a visible lens and the raphe runs around three-quarters of the seed circumference; and P. grandiflora-type bears a one-lipped rim aril. Poecilanthe presents a remarkable diversity both in seed and embryo, which reinforces the belief that the genus is not monophyletic. Moreover, our results support the three major clades recognized by a preliminary phylogeny.
