royal palm

The royal palm belongs to the genus Roystonea and is primarily found in the Caribbean region. A notable species is Roystonea regia, a tall, graceful palm with pinnate leaves, which is widely cultivated for ornamental purposes.1

Palm stems, including those of royal palms, differ from typical woody trees. They are composed of numerous conducting strands scattered within softer tissue, with a harder outer region of densely packed fibers. This unique construction allows palms to withstand strong winds that might break ordinary trees. Unlike woody plants, palms do not have a cambium layer for thickening their trunks; instead, any thickening occurs due to an increase in the size or number of internal cells.2
