PETIOLE : long, aculeate, spines either patent or pointing downwards, geniculate apically, sheath short. BLADE : unarmed, sagittate to hastate or almost tripartite, coriaceous, posterior divisions ± equalling anterior, sometimes longer; basal ribs well-developed, primary lateral veins mostly arising near petiole insertion, long-arcuate towards division apex and running into margin, higher order venation reticulate. INFLORESCENCE : solitary. PEDUNCLE : subequal to petiole and similar in appearance. SPATHE : ovate-lanceolate, fully expanded, persistent, red brown. SPADIX : shorter or equalling spathe, cylindric, stipitate, stipe basally adnate to spathe, flowering sequence basipetal. FLOWERS : bisexual, perigoniate; tepals 4-6, fornicate. STAMENS : 4-6, filaments free, oblong, flattened, connective slender, thecae ellipsoid, dehiscing by longitudinal slit. POLLEN : monosulcate, ellipsoid-oblong, small (mean 18 µm.), exine scabrate or verruculate, minutely foveolate between verruculae. GYNOECIUM : cylindric to obovoid, ovary 1-locular, ovule 1, anatropous, placenta parietal to subbasal, stigma discoid- hemispheric.
