The plant is a rosette herb consisting of several leaves with a sagittate (arrowhead shaped) lamina or blade up to long by wide, borne on very stout petioles or stalks up to in length. More recently, Anthony Lamb of the Sabah Agricultural Department found and measured one individual with a lamina in length. The inflorescence is the spathe and spadix typical of the Arum family, with the spathe being a very dark blackish-purple color. This species was unknown to science prior to 1967. The plant is usually trunkless. References robusta
