Arecaceae The palm family Characters, Distribution and Types

The Arecaceae angiospermic plants family, commonly known as the palm family, is a diverse group of flowering plants characterized by distinguishing features/characters. Here are some general characters of the Arecaceae angiospermic family:

Diagnostic characteristics of Family Arecaceae:

1. Leaves:
Palm leaves, generally known as fronds, are usually large and compound, consisting of multiple leaflets (small leaf) connected to a central stalk (rachis). The positioning of leaflets can be pinnate (feather-like) or palmate (fan-like).

2. Stems:
Palms have a characteristic unbranched stem commonly known as a trunk. The trunk maybe slender / robust, and it is mostly covered/surrounded with leaf bases that persist or fall away, leaving distinctive patterns/symmetry.

3. Inflorescence:
The inflorescence of palms is generally a large in size, complex structure/formation called a spadix or spike (thorny structure). It is composed of numerous/unlimited tiny flowers arranged in clusters.

4. Flowers:
Palm flowers are often tiny / small and inconspicuous. They are usually unisexual (having separate sexes flowers), with male and female flowers existing on the same or different plants (dioecious / monoecious). The flowers of this family are mostly surrounded by a protective and supportive structure called a spathe.

5. Fruit:
The fruit of Arecaceae angiospermic plants family (palms) is diverse and can be a: i- drupe, ii- berry, iii- or nut. Palms are known for producing a huge variety of edible fruits, including: i- coconuts, ii- dates, iii- and oil palms.

6. Roots:
Arecaceae angiospermic plants family (Palms) often have fibrous or adventitious roots that generates from the base of the stem or from the trunk. These roots assist provide strength and support in the often sandy or watery soils where palms thrive.

7. Economic importance:
Many Arecaceae angiospermic plants family (palms) have vital economic importance. They are cultivated by farmers for their fruits, nuts, oils, and ornamental value (having scented smell). Examples include the: i- coconut palm botanically known as cocos nucifera, ii- date palm botanically known as (Phoenix dactylifera), iii- and oil palm botcanically known as (Elaeis guineensis).

8. Habitat:
Palms are found in a wide range of zones, from rainforests and deserts to grasslands and coastal zones of the globe. They are often associated with tropical and subtropical regions but can also be found in temperate climates (where temprate is high).

These general characters help distinguish palms within the Arecaceae angiospermic plants family, a group that comprises a large number of members/species with various sizes, forms, and ecological adaptations.
