Mother Nature Network states that there are over 2,500 species of palm trees worldwide. These fall into the family Arecaceae, and they are found in warm climates ranging from the desert to the rain forest. Not all palms are definitive trees; some grow as shrubs and vine-like plants. A characteristic of all palm trees is that they have two kinds of leaves. The pinate leaves are like feathers, and they grow out of the side of the trunk or stem. The palmate leaves are longer and larger, and they grow out of the end of the trunk in a large bunch.
