Schoenoplectiella juncoides is a sedge (a member of the Cyperaceae family), native to east Asia and Oceania.

S. juncoides is a species that is native to Hawaii and is usually found on high elevations near wetlands.

Although this plant usually grows on high elevations, 180–1,300 m (590–4,270 ft), it thrives in wet or moist conditions.

The root system and structure of this species may prevent erosion by anchoring the soil in place which leads to the improvement of the water quality.

However, farmers are also able to reduce the amount of vegetative sprouts that grow by flooding the field with water, which is also known as wet puddling.

S. juncoides are used as a food source in some countries by using the seeds from the fruiting body to make bread or porridge.
