The leaf blades can be up to 30 cm (1 ft.) wide and 1 meter (~3 ft.) long and are attached at an angle to the petiole. This is the 'bent' in the common name and the species name, as geniculata means 'with a knee-like bend'. The tips of the leaves often reach from two to three meters (~ 6 to 9 ft.) high.
