rush

Any of several flowering plants distinguished by cylindrical stalks or hollow, stemlike leaves. They are found in temperate regions, particularly in moist or shady locations. The rush family (Juncaceae) includes the genera Juncus, the common rushes, and Luzula, the wood rushes. In many parts of the world, common rushes are woven into chair bottoms, mats, and basketwork, while rush pith serves as wicks in open oil lamps and tallow candles (rushlights). Other rushes include the bulrush (family Typhaceae), the horsetail (or scouring rush), the flowering rush (Butomus umbellatus, family Butomaceae), and the sweet rush, or sweet flag (Acorus calamus, family Acoraceae).
