Description

The large cordate or sagittate leaves grow to a length of 20 to 90 cm on long petioles. Their araceous flowers grow at the end of a short stalk, but are not conspicuous; often hidden behind the leaf petioles. The stem (a corm) is edible, but contains raphid or raphide crystals of Calcium oxalate along with other irritants (possibly a protease) that can numb and swell the tongue and pharynx resulting in difficult breathing, and sharp throat pain. The lower parts contain more of the poison. Prolonged boiling before serving or processing may reduce the risks but acidic fruit such as tamarind may dissolve them.
