" Most dictionaries define tree as a large, perennial, single-trunked, woody plant. This is misleading, for a palm tree contains no wood. Botanists themselves do not bother to distinguish trees from nontrees. Instead, they divide plants into more precise categories, such as angiosperms (flowering plants) and gymnosperms (nonflowering). Angiosperms comprise two diagnostic types, monocots and dicots. Monocots, including palms, are less complex than dicots. They develop from a single embryonic leaf, have basic flowers and no secondary growth (wood). The rootstock is adventitious, meaning that the underground shoots develop independently; the tree has no radicle, or primary root. The simplicity of monocots enhances their agricultural tility. As crops, they supply us with essential carbohydrates—think bananas, yuccas, and edible grasses (rice, wheat, maize, cane). From a botanist’s point of view, a palm is not so different from a giant stalk of grass. "
