Geophytic herb. Stem hypogeous, tuberous, globose to subglobose. Leaf solitary, erect; petiole with very short sheath, leaf blade pinnatipartite, venation reticulate. Inflorescences solitary or in pairs, appearing before the leaf, erect at anthesis; peduncle longer or a little shorter than the petiole; spathe erect, weakly differentiated into tube and lamina, lower part convolute; spadix adnate to the spathe in the basal portion of the female zone; female flowers densely arranged, male zone with no sterile flowers in basal portion. Flowers diclinous, naked; male flowers (synandria) 2-3-androus, anthers subsessile, only fused at base, thecae subglobose, dehiscing by an apical longitudinal slit; pollen inaperturate, gemmate, ± globose to ellipsoid; female flowers surrounded by 4-6 obpyramidal free staminodes strongly papillate at apex, overy ovoid, 4-5-locular, each locule with a single orthotropous ovule, placentation basal. Infructescence partially covered by the remaining spathe, berries densely arranged, fleshy, seeds with smooth testa, endosperm copious.
Geophytic; flowers unisexual, perigone absent; spadix fertile to apex; ovules orthotropous. Differs from Asterostigma, in leaf blade always pinnatipartite, synandrium incompletely fused (usually only at base) with connectives of each stamen free, thecae elliptic and seedling leaves exclusively cordate. Differs from Gorgonidium by staminodes with conspicuously papillate connectives, short synandrium filaments and very slender habit.
