The plant's leave blades are elongated (long and thin) and leathery. They can be up to long and wide. The leaf stems are generally shorter than the blade. The leaves are set on a creeping and rooting rhizome. It is thick. The spathe is long (sometimes up to 9 cm long). It has a long peduncle. The spadix is long (sometimes up to 12 cm long). It is a little bit longer than the spathe. Therefore, the tip of the spadix sticks a little bit out of the spathe. The upper part of the spadix is covered with male flowers. Their 5-6 stamens are fused. The anthers (also called thecae) are on the sides. The lower part of the spadix is covered with female flowers. These are reduced to the ovary and stigma.
