Another difference can be seen in the placement of petiole. When the petiole of Alocasia is attached to the notch, the petiole in colocasia is attached a bit down the notch.
Another significant difference can be seen in the female flowers of the two plants. The placenta is Alocasia plant is basal. The stem and the ovaries are attached to this placenta along the interior base. On the other hand, the placenta in colocasia is seen next to the inner side. The stem and the ovaries are connected with the placenta through the interior sides of ovary.
