Abstract
Herbs, rhizome repent, much branched, lacunose, with aromatic oil cells; leaves distichous, unifacial, ensiform, not differentiated into petiole and blade, venation strictly parallel; intravaginal squamules present in leaf axils; inflorescence solitary, terminal, borne laterally on leaflike axis; spathe longer than spadix, erect, persistent, appearing merely as extension of leaflike peduncle; spadix conic-digitiform or slender and tail-like, densely flowered throughout; flowers bisexual, bractless, 3-merous, perigoniate; tepals in 2 whorls of 3, thin, fornicate; stamens in 2 whorls of 3; filaments linear-elongate; anthers introrse; thecae rounded-elliptic, subopposite, opening by longitudinal slit; gynoecium obconic-oblong, equalling the tepals, 2–3-locular; placenta apical; ovules several per locule, pendent, atropous; both integuments bearing trichomes, inner integument longer than outer and forming the micropyle; stigma minute, sessile; berry oblongobovoid with thin, leathery pericarp, whitish with brownish stigma remnant when fresh, soon drying to straw-brown, enclosed by tepals, 1–5(-9)-seeded; seeds oblong to ellipsoid, with perisperm and abundant endosperm, testa light brown, foveolate or smooth; embryo axile, cylindric.
