Family Juncaginaceae

Synonyms: Lilaeaceae APNI*

Description: Annual or perennial glabrous herbs, tufted or rhizomatous, often with tubers, rarely bulbous, emergent when aquatic.

Leaves basal, ± linear to terete, often spongy, erect to floating; leaf sheath open, apically tapered, ligulate or auriculate.

Inflorescence a raceme or spike, usually bractless, terminal on an axillary scape, rarely also with 2 sessile female flowers at scape base. Flowers mostly bisexual, sometimes unisexual. Perianth often of 3 free tepals or of 6 in 2 similar alternate whorls, less commonly tepals 0 or 1–5, deciduous. Stamens 1–6, each inserted on base of tepal and falling with it; anthers sessile or subsessile, 2-locular, longitudinally dehiscent, extrorse, each shorter than its tepal and usually enveloped by it. Gynoecium superior; carpels usually 1 or 3–6, sometimes 2, 7 or 8, free or united ventrally, often 3 of the carpels sterile and forming a central axis; ovule 1 per carpel, basal or apical; style mostly short and thick, rarely thread-like; stigma papillose or hairy.

Fertile fruiting carpels hard or follicle-like or an achene, indehiscent or opening ventrally, mostly separating and falling at maturity; 3 fertile carpels alternating with the 3 sterile ones of the central axis when this is present. Seed solitary, non-endospermic; embryo straight.

Distribution and occurrence: World: 3 genera, 35 species, subcosmopolitan, mostly temperate, but cente of specific diveristy in Australia. Australia: 2 genera, c. 20 species, all States.
