Palm, or Palms, or Arecaceae [2] (lat. Arecáceae, Pálmae, Palmáceae) is a family of monocotyledonous plants.

It is represented mainly by woody plants with unbranched (except for the doom palm) trunks, in which primary thickening occurs (that is, thickening due to the activity of the protoderm and the main meristem). There are also a number of species that are characterized by thin creeping or climbing shoots (for example, representatives of the genus Calamus) [3]. The family includes 185 genera and about 3400 species.
