Drift seed

Drift seeds, also known as sea-beans in the United States, are a type of seed that is dispersed by water. These seeds are typically hardy and able to survive long periods of time in water, allowing them to travel great distances before finding suitable conditions for germination.

Overview

Drift seeds are produced by a variety of plant species, including those found in tropical rainforests and coastal regions. The seeds are often large and buoyant, with a hard outer shell that protects the seed during its journey. Some drift seeds are also able to float on the ocean's surface, carried by currents and tides to new locations.

Dispersal

The primary method of dispersal for drift seeds is through water. This can occur in a number of ways, including via rivers, floods, and ocean currents. Some seeds are also dispersed by animals, either through ingestion and excretion or by attaching to the animal's fur or feathers.

Ecological Importance

Drift seeds play a crucial role in the ecology of many ecosystems. They contribute to the diversity of plant life in an area by introducing new species and genetic material. This can lead to increased biodiversity, which is important for the health and resilience of ecosystems.

Examples of Drift Seeds

There are many examples of plants that produce drift seeds. These include the sea heart (Entada gigas), the monkey ladder (Entada phaseoloides), and the sea purse (Dioclea reflexa).
