    Habitat
    Tropical humid forest; helophytes in swamp forest, marshes, stream margins, open or shaded sites, in peat or sand.
    General Description
    HABIT : unarmed herbs, sometimes robust (to 2m), rhizome subterranean, erect, sparsely branched, sometimes bearing a few subterranean tubercles. LEAVES : several, ± erect. PETIOLE : long, smooth to roughened-verruculate, often transversely variegated, geniculate at apex, sheath less than half petiole length. BLADE : deeply sagittate to subtripartite, often with a few perforations of irregular size between primary lateral veins; basal ribs very well-developed, primary lateral veins mostly arising near petiole insertion, very long-arcuate towards apex of each division, running into margin, higher order venation reticulate. INFLORESCENCE : solitary, appearing with leaves. PEDUNCLE : shorter than petiole. SPATHE : marcescent, tube with convolute margins, longitudinally white-striped, blade strongly fornicate, usually obscuring mouth of tube, brown-purple. SPADIX : sessile to shortly stipitate, cylindric, obtuse, shorter than spathe tube, flowering sequence basipetal. FLOWERS : bisexual, perigoniate; tepals 4, fornicate, subtruncate. STAMENS : 4, strongly exserted from flower at anthesis, anthers longer than connective, connective slender, thecae ovate-elliptic, dehiscing by pore-like apical slit. POLLEN : monosulcate, ellipsoid-oblong, small (mean 23 µm.), exine subreticulate. GYNOECIUM : ovate-conoid, ovary 2-locular, ovules 1 per locule, anatropous, placenta axile, style attenuate, longer than tepals, stigma small, button-like. BERRY : obovoid, somewhat furrowed, 1-2-seeded, dark purplish-red. SEED : reniform, attenuate towards micropyle, testa strongly dentate-cristate, thick, hard, brown, embryo curved, endosperm present.
    Distribution
    E. Brazil.
    Diagnostic
    Helophytes with deep, erect, subterranean rhizome; petiole smooth to verruculate, geniculate at apex; leaf blade deeply sagittate to subtripartite; spadix hidden by spathe; flowers bisexual, perigoniate; seed reniform, strongly dentate-cristate. Differs from Urospatha in having a fornicate (arched forward and down) spathe, leaves often sparsely perforated, and endemism to Brazil (coastal Bahia and Espirito Santo).
