Cyperaceae
Spikes of sedge (Carex pendula).
The Chinese water chestnut (Eleocharis dulcis) is a member of the sedge family (Cyperaceae). It is widely cultivated in Asia for its edible corms, which are the parts of the plant that are eaten. These corms are valued for their ability to remain crisp even after being cooked, making them a characteristic ingredient in many Chinese dishes. While sometimes referred to as tubers, these edible structures are botanically classified as corms.12
