These aberrations suggest the habit operates on a single gene. Palms which are usually solitary may grow in clusters and vice versa. Several palm genera have both solitary and clustering members. Exclusively sympodial genera include many of the rattans, Guihaia, and Rhapis. The new shoot, in turn, produces an axillary bud and a clustering habit results. The trunk develops an axillary bud at a leaf node, usually near the base, from which a new shoot emerges. Palms may instead grow in sparse though dense clusters. Some common palms restricted to solitary growth include Washingtonia and Roystonea. This monopodial character may be exhibited by prostrate, trunkless, and trunk-forming members. The common representation is that of a solitary shoot ending in a crown of leaves. Whether as shrubs, tree-like, or vines, palms have two methods of growth: solitary or clustered. The suffix -aceae is the feminine plural of the Latin -āceus ("resembling"). Areca is derived from Portuguese, via Malayalam അടയ്ക്ക ( aṭaykka), which is from Proto-Dravidian *aṭ-ay-kkāy (“areca nut”). The word Arecaceae is derived from the word areca with the suffix "-aceae". For inhabitants of cooler climates today, palms symbolize the tropics and vacations. In many historical cultures, because of their importance as food, palms were symbols for such ideas as victory, peace, and fertility. In contemporary times, palms are also widely used in landscaping. Many common products and foods are derived from palms. They have been important to humans throughout much of history. Palms are among the best known and most extensively cultivated plant families. However, palms exhibit an enormous diversity in physical characteristics and inhabit nearly every type of habitat within their range, from rainforests to deserts. ![]() Most palms are distinguished by their large, compound, evergreen leaves, known as fronds, arranged at the top of an unbranched stem. Currently, 181 genera with around 2,600 species are known, most of which are restricted to tropical and subtropical climates. Those having a tree-like form are called palm trees. Their growth form can be climbers, shrubs, tree-like and stemless plants, all commonly known as palms. The Arecaceae is a family of perennial flowering plants in the monocot order Arecales. Well over 2600 species in some 202 genera
