Dicotyledons, or "dicots", is a name for a group of
flowering plants whose
seed typically contains two embryonic leaves or
cotyledons. There are around 199,350
species within this group
[1]. Flowering plants that are not dicotyledons are
monocotyledons, typically having one embryonic leaf.The dicotyledons no longer are regarded as a "good" group, and the names "dicotyledons" and "dicots" are no longer to be used at least in a taxonomic sense. The vast majority of the former dicots, however, form a
monophyletic group called the
eudicots or tricolpates. These may be distinguished from all other flowering plants by the structure of their
pollen. Other dicotyledons and monocotyledons have monosulcate pollen, or forms derived from it, whereas eudicots have tricolpate pollen, or derived forms, the pollen having three or more pores set in furrows called colpi.
