Endemic to the tidal shores of the Nusaran Sandstone Caves, the umin (or seaballoon) is a resilient coastal plant adapted to the interplay of sand, salt, and stone. Known locally for the buoyant, air-filled shape of its fruit, the shrub is a vital part of the local cave-beach ecosystem.

Etymology

Unknown.

Morphology

The umin shrub grows low and laterally. From late Summer through early Winter, the plant produces orange flowers directly in the shallows, often half-submerged. The fruit are large, light green, cylindrical capsules filled with airy pulp and clusters of soft seeds. These balloon-like fruits bob lightly on waves.

Physiology

The roots stabilize the plant against waves and erosion while reaching down to mineral-rich sublayers.

Mechanisms

Fruits are buoyant to aid in dispersal. Germination is triggered by alternating cycles of wetting and drying.

Behavior

Life Cycle

Young shrubs quickly develop a deep, tenacious root system.

Ecology

The umin’s life cycle is intimately tied to the sandstone cansbiah, which feeds on both flowers and fruit and aids in pollination and seed dispersal.
