The Arecaceae is a monocot order of perennial flowering plants in the Arecaceae family. Palms come in a variety of forms, including climbers, shrubs, tree-like plants, and stemless plants. Palm trees are those that have a tree-like shape. There are now 181 genera and 2,600 species, the majority of which are confined to tropical and subtropical regions. The enormous, complex, evergreen leaves known as fronds, placed at the summit of an unbranched stem, identify most palms. Palms, on the other hand, have a wide range of morphological features and may be found in virtually every sort of environment, from rainforests to deserts.

Palms are one of the most well-known and widely cultivated plant families. They have played an essential role in human history for a long time. Palms are used to making a variety of goods and meals. Palms are one of the most commercially significant plants nowadays since they are frequently utilized in landscaping. Palms were emblems for such ideals as a triumph, peace, and fertility in many historical societies due to their value as food. Palm trees have come to signify the tropics and holidays for those living in colder regions.

The name Arecaceae comes from the suffix “-aceae” added to the word areca. Areca comes from Portuguese (aaykka) through Malayalam (aaykka), which comes from Proto-Dravidian *a-ay-key (“areca nut”). The feminine plural of the Latin suffix -ceus is -aceae (“resembling”).

Palms can develop in two ways: solitary or clustered, whether as shrubs, trees, or vines. A single branch with a crown of leaves is the most typical depiction. Prostrate, trunkless, and trunk-forming members can all display this monopodial trait. Washingtonia and Roystonea are two common palms that are confined to solitary growth. Palms can also be found in scattered yet dense groups. At a leaf node, generally towards the base, the trunk forms an axillary bud from which a new shoot arises. The new shoot then develops an axillary bud, resulting in a clustering habit. Many rattan genera, as well as Guihaia and Rhapis, are exclusively sympodial. Solitary and clustered palms are found in several taxa. Palms that are normally solitary can form clusters and vice versa. These anomalies imply that the behavior is controlled by a single gene.

Palms feature enormous, evergreen leaves that are complex and spirally oriented at the top of the stem, either palmately (‘fan-leaved’) or pinnately (‘feather left). At the base of the leaves is a tubular sheath that breaks apart on one side when mature. The inflorescence consists of a spadix or spike surrounded by one or more bracts or spathes that mature into the wood. The blooms are usually tiny and white, radially symmetric, and unisexual or bisexual in nature. The sepals and petals are generally three in number and maybe separate or united at the base. The stamens are usually six in number, with filaments that are either independent, connected to each other, or joined to the base of the pistil. The fruit is generally a single-seeded drupe (occasionally berry-like), although other genera (such as Salacca) have two or more seeds per fruit.
