Small perennial terrestrial herbs with creeping slender underground rhizome. Leaves several, subtended basally by small cataphylls; petiole lacking apical pulvinus; sheath inconspicuous; blade cordate-ovate; main side veins excurrent into margins, finer venation reticulate. Inflorescence appearing with leaves, longer than petiole; peduncle slender. Spathe simple, broadly ovate-elliptic to subcircular, expanded, arching backwards, persistent in fruit, mucronate to shortly acuminate, decurrent at base. Spadix shorter than spathe, basal pistillate part adnate on one side to spathe and ± contiguous (naked interstice sometimes present) with free apical staminate part. Flowers unisexual, lacking perigon. Stamens free, densely congested, sessile; anthers dehiscing by short apical elliptic pores; connective ± slender. Pistils few, narrowly flask-shaped, ± distant towards base of spadix; ovary unilocular, with single basal ovule; stigma capitate on slender attenuate style. Berries elliptic, 1-seeded. Seed with endosperm; embryo elongate.
Laticifers simple, articulated. HABIT : small evergreen herbs, stem a slender hypogeal rhizome, internodes very short. LEAVES : usually minutely hispid on petiole and abaxial surface of blade. PETIOLE : sheath very short. BLADE : cordate-ovate; primary lateral veins pinnate, running into marginal vein, higher order venation reticulate. INFLORESCENCE : 2 in each floral sympodium, appearing with the leaves. PEDUNCLE : slender, equalling or longer than petiole, sometimes exceeding entire leaf. SPATHE : broadly ovate-elliptic to subcircular, acuminate, decurrent, white, ± fully expanded and sometimes arching backwards at anthesis, persistent, closing at fruiting stage. SPADIX : shorter than spathe, female zone entirely adnate to spathe, ± laxly flowered with gynoecia ± biseriately arranged, contiguous with male zone or with short, naked axis in between, male zone equalling female, cylindric, densely flowered, fertile to apex. FLOWERS : unisexual, perigone absent. MALE FLOWER : probably 1-androus (2-3-androus according to Engler 1920a), stamens free, depressed subquadrate, anthers sessile, thecae opposite with subovoid microsporangia dehiscing by single apical pore. POLLEN : inaperturate, spherical to subspheroidal, medium-sized (mean 37 µm.), exine papillate-spinose. FEMALE FLOWER : gynoecium slender, flask-shaped, falcate, yellowish, ovary 1-locular, ovule 1, anatropous, placenta basal, style rather long-attenuate, stigma small, subhemispheric, slightly wider than style. BERRY : ellipsoid and slightly angled, style forming persistent mucro, green. SEED : ellipsoid, testa ± smooth, thin, embryo elongate, straight to slightly curved, endosperm copious.
Small rhizomatous geophyte; leaf blade with reticulate fine venation; spadix fertile to apex; flowers unisexual, perigon absent; stamens free; gynoecium slender, flask-shaped with tapering style. Differs from Nephthytis in having cordate-ovate leaves, which are minutely hispid, a pure white spathe and female zone of spadix adnate to the spathe.
