Order LXXXIII. JUNCACEÆ.
Perennial, rarely annual herbs. Rootstock short, stout, scaly. Stems usually simple, slender, stiff, erect, cylindrical or compressed, sometimes septate within. Leaves usually all radical, often rigid and terete like the stems, sometimes flat and grassy, occasionally absent or reduced to sheaths. Flowers small, green or brown, regular, hermaphrodite or more rarely unisexual, in axillary or terminal cymes or clusters, rarely solitary. Perianth inferior, coriaceous or scarious, persistent; segments 6 in 2 series, imbricate. Stamens usually 6, inserted on the bases of the perianth-segments, the 3 interior sometimes wanting; filaments free, flattened or filiform; anthers 2-celled, introrse. Ovary superior, 1-celled or 3-celled; style short or long; stigmas 3, filiform; ovules few or many, anatropous. Fruit a 1- or 3-celled capsule, loculicidally 3-valved. Seeds few or many, erect; testa membranous, often lax at each end; albumen copious, fleshy; embryo minute.
An order of moderate size, comprising 14 genera and about 250 species. The two typical genera (Juncus and Luzula) are widely dispersed, especially in temperate or extratropical regions; the remainder of the order is mainly Australian. The species have no important properties and cannot be said to possess any economic value.
