Pandanus, commonly known as screw pines, is a genus of monocotyledonous plants found in tropical and subtropical regions. These plants are notable for their unique spiral arrangement of leaves and their importance in cultural, economic, and ecological contexts.

Pandanus species are typically small trees or shrubs with prop roots that provide stability. Their leaves are long, narrow, and arranged spirally, often with spiny margins. The plants produce large, woody fruits composed of multiple segments.
Pandanus species are distributed across Southeast Asia, the Pacific Islands, Madagascar, and parts of Australia. They thrive in coastal areas, mangroves, and wetlands, often playing a role in stabilizing sandy soils and preventing erosion.
In many cultures, Pandanus leaves are used for weaving mats, baskets, and traditional clothing. The fragrant flowers and leaves are also used in rituals and ceremonies, symbolizing purity and prosperity.
Pandanus differs from related genera in its distinctive spiral leaf arrangement and prop roots. Unlike palms, Pandanus leaves are narrower and often spiny, and their fruits are segmented rather than single drupes.
While many Pandanus species are abundant, some are threatened due to habitat loss, coastal development, and overharvesting. Conservation efforts focus on protecting coastal ecosystems and promoting sustainable use of Pandanus resources.
