    Distribution
    Thailand to Borneo.
    Habitat
    Tropical humid forest; rheophytes.
    Diagnostic
    Small to medium-sized rheophytes; petiole sheath with a long marcescent ligule; leaf blade apex with tubular mucro, fine venation parallel-pinnate; spathe blade falling or deliquescent after anthesis; flowers unisexual, perigone absent; anther thecae lacking horn- or needle-like projections. Differs from Schismatoglottis in lacking spathe constriction, long-ligulate petiole sheaths, spadix fertile almost to apex and hemiorthotropous to orthotropous ovules.
    General Description
    HABIT : small to medium-sized evergreen herbs, stem erect or decumbent. LEAVES : several. PETIOLE : sheath short with long, marcescent ligule. BLADE : elongate-lanceolate to elliptic or oblanceolate, coriaceous, apex with tubular mucro; primary lateral veins pinnate, running into distinct marginal vein, secondary laterals and higher order venation parallel-pinnate. INFLORESCENCE : solitary, usually nodding. PEDUNCLE : subequal to or longer than petiole. SPATHE : stoutly ellipsoid, not constricted, often pink, lower part persistent and cup-like, upper part slightly gaping at anthesis, caducous or deliquescent, cuspidate to acuminate. SPADIX : sessile with ± oblique insertion, sometimes with sterile female flowers at extreme base, female zone cylindric, shorter and contiguous with male, or separated by a short zone of sterile male flowers, male zone cylindric, equal in thickness to female, obtuse, fertile to apex or with a few sterile terminal flowers. FLOWERS : unisexual, perigone absent. MALE FLOWER : 1-2-androus, stamens free, compressed, anthers truncate, connective ± flat or expanded apically or with conical beak ( P. insignis), overtopping thecae, thecae oblong-ellipsoid, dehiscing by apical pore. POLLEN : inaperturate, ellipsoid, small to medium-sized (mean 25 µm.), exine psilate. STERILE MALE FLOWERS : apparently composed of a single truncate, subclavate, prismatic staminode. FEMALE FLOWER : gynoecium free or cohering to neighbouring ones, ovary 1-locular, ovules many, hemiorthotropous to almost orthotropous and erect, funicle long, placentae 2-4, parietal or parietal and basal, stigma sessile, as broad as ovary, contiguous with adjacent ones. BERRY : obovoid, green. SEED : elongate-ellipsoid to cylindric, with long, curved micropylar appendage, testa slightly costate, embryo elongate, endosperm copious.
