Rhizome imperfectly known, but slender, branching, brown in colour with white flesh. Stem smooth. Leaves cordate-sagittate with rather elongated auricles that are distally rounded, 9 cm long by 8 cm across the auricles and 4 cm above them; primary nerves 5, the two outer forking and curving in the auricles; upper surface shining; lower dull; petiole about as long as the blade. Male flowers in small cymes disposed on solitary, probably horizontal, rather stiff axes which sometimes carry small branches at the base; the cymes up to 2 cm apart; axis angled, to 30 cm long; pedicels to 1 cm long. Tube of the flower extremely short; tepals ovate, spreading in anthesis so much as to make the flower almost patelliform. Outer tepals a little broader than the inner ones, to 1.5 mm in length. Stamens 6, on very short filaments which raise the anthers so that they touch at the centre of the flower. Female plant unknown.
