Plant very small, acaule, entirely glabrous, developing from a subglobular tubercle about 1 cm in diameter. Leaves most often solitary, sometimes 2-3; petiole 1-4 mm long; limb equilateral, orbicular or suborbicular, long and 1-3 cm wide, sometimes a little decurrent on petiole palmatinerve; very thin veins.

Stamens 3-5 with lightly welded threads at their base, free on 1.5 mm; oblong antheres, obtuse, 1 mm long. FEMALE flower with pedicel 1-2 mm long; 4 tepals oblong, subequal, 1-2 mm long.
