    • Plant Morphology :
      Growth Form: It is a herb, up to 150 cm tall with a thickened lower stem (corm) up to 60 cm long.
      Foliage: Its alternate, stalked leaves have leaf blades that are arrow head-shaped, dark green above, light green or purple on the underside, and 25-85 by 7-40 cm, with or without whitish veins. Its chocolate brown leaf stalk is usually mottled.
      Flowers: Its flowers grow in a 6-13 cm long shoot enclosed by a greenish to white colour modified leaf (spathe) that is 9-10 cm long.
      Fruits: Its fruits are round, orange, 4-7 mm long, and contain one large seed.
      Habitat :

      Associated Fauna :
      The flowers are pollinated by flies. The fruits are probably eaten by small mammals and birds.
      Cultivation :
      It can be propagated by seed, or division of the buds off the corm.
