Palms decorate tropical and subtropical regions of the World
Palms are monocots. Angiosperms or true flowering plants are divided into two major groups—monocots and dicots, which have various differences, but are named for the number of seed leaves or cotyledons they have.
Monocots also include grasses, orchids, gingers, bananas, and bamboo. Also, most of the bulbs including onions, garlic, lilies, tulips, and more, but probably most important characteristic for our discussion on palms, there is no real wood with annual rings. The vascular tissue (the phloem and xylem) in monocots is arranged in bundles throughout the stem. In a dicot, they occur in the cambium layer just under or inside the bark around the plant stem. It is the new set of xylem and phloem cells that are produced each year which form the annual rings that produce the wood in true trees.
