Perennial herbs or subshrubs, with rather strict rush-like stems, usually glabrous or glabrescent. Leaves sessile, opposite; blades linear or filiform, rather rigid and usually erect or nearly so, acute and hard-pointed, the margins revolute; stipule sheath mostly tubular, truncate or sometimes with 2 small cusps. Flowers 4-merous, in small rather dense terminal and axillary capituliform, umbelliform or cymose inflorescences, sometimes combining to form a more ample inflorescence; bracts connate in pairs. Calyx lobes triangular; corolla mostly white, tube cylindric or somewhat funnel-shaped, throat ± densely hairy, lobes ovate or ovate-oblong, hairy in lower half inside. Stamens included in the tube in long-styled flowers, exserted in isostylous and short-styled flowers; filaments glabrous; anthers dorsifixed. Ovary 2-locular; ovules fairly numerous on peltate slightly stipitate; style glabrous; stigma lobes filiform, densely covered with long papillae. Disk cushion-shaped, farinose. Fruit capsule globose, only slightly beaked, the beak dehiscing loculicidally. Seeds dark brown, dorsiventrally compressed, oblong, smooth.
