The arecáceas (family Arecaceae) are a family of monocotyledonous plants, the only family of the order Arecales. They are usually known as palms or palms. Individuals in this important family are easy to recognize visually, although there may be confusion with species in the Cycadaceae and Zamiaceae families due to morphological similarities. They are woody plants (but without secondary trunk growth, only primary). Despite being monocotyledonous, many of them are arborescent, with large crown leaves at the end of the stem, generally pinnate (pinnatisectas) or palmate (palmatisectas). Its flowers have 3 sepals and 3 petals, and are arranged in inflorescences with one or more spathe. The fruit is fleshy: a berry or a drupe. They are widely distributed in tropical to temperate regions, but mainly in warm regions.
