A species of tree having several varieties, of which the familiar "itching palm" (_Palma hominis_) is most widely distributed and sedulously cultivated. This noble vegetable exudes a kind of invisible gum, which may be detected by applying to the bark a piece of gold or silver. The metal will adhere with remarkable tenacity. The fruit of the itching palm is so bitter and unsatisfying that a considerable percentage of it is sometimes given away in what are known as "benefactions."

Any endogenous tree of the order Palmæ or Palmaceæ; a palm tree.

a monocot plant has scattered vascular bundles that carry both the water-conducting cells and the food-conducting cells up to the crown and down to the roots

an evergreen tree and a monocot

This effect might remind you of looking at a palm tree.

The word Palm should be used as opposed to the commonly used phrase 'Palm Tree' as Palms are not trees by definition as they do not form wood as a tree does, nor do they form bark. Palms have a hard stem that contains bundles of conductive vessels scattered throughout softer tissue. Secondary thickening of the stem is absent, or slight, and even then it is not cambial but from divisions in the ground parenchyma. This type of structure not only provides the Palm trunk with strength but also stability. Palm root systems are also not woody like a tree and they invariably do not 'branch'. Therefore the phrase 'Palm Tree' is a contradiction in terms and we should more correctly just say 'Palm'.
