    Habitat
    Tropical humid forest (“terra firme”); terrestrial, creeping in leaf litter on sandy soil.
    General Description
    HABIT : evergreen herbs with creeping rhizomatous stem, cataphylls marcescent, persistent and entire, drying reddish-brown. LEAVES : erect, several. PETIOLE : shortly-sheathed, pilose, weakly geniculate at apex and base. BLADE : ovate, base rounded, apex acute; primary lateral veins pinnate, ca. 12 per side, glabrous adaxially, minutely pilose abaxially especially along veins, running into marginal vein, secondary laterals arcuate and ± parallel to primaries, finer veins reticulate. INFLORESCENCE : solitary, erect. PEDUNCLE : shorter than petiole, subtended by 3 cataphylls. SPATHE : erect, broadly ovoid, convolute in lower two-thirds, not constricted, apiculate, persistent. SPADIX : subequal to spathe, fertile to apex or most apical flowers sterile, female zone laxly flowered and entirely adnate to spathe, separated from male zone by very sparsely flowered sterile zone, male zone densely flowered. FLOWERS : unisexual, perigone absent. MALE FLOWER : 3-4-androus, stamens connate into a synandrium, synandria truncate, irregularly rhombic, somewhat domed, usually with central slit, common connective very thick, thecae ellipsoid-oblong, lateral, dehiscing apically by very broad slit. POLLEN : inaperturate, broadly ellipsoid, large (50-60 µm.), exine scabrate to nearly smooth (psilate). STERILE MALE FLOWERS : each usually consisting of 4 staminodes, those of lower flowers ± free and roundish, upper ones nearly completely connate and irregularly formed, sometimes all 4 connate with a central slit. FEMALE FLOWER : gynoecia arranged in somewhat distant spirals, ovary depressed globose, 1-locular, ovule 1, anatropous, funicle short, placenta basal, stigma sessile, discoid, broad. BERRY : unknown. SEED : unknown.
    Diagnostic
    Evergreen herb with creeping rhizomatous stem; petiole weakly geniculate; leaf blade simple, entire, ovate; female zone of spadix entirely adnate to spathe, with flowers laxly arranged; male flower forming a truncate synandrium. Differs from Dieffenbachia in lacking aerial stem, reticulate higher order leaf venation, female flowers without staminodes.
    Distribution
    N. Brazil.
