The 1 to 5 central spines range from yellowish to pink to brownish and are 1 to 25 mm (0.039 to 0.984 in) long. The funnel-shaped flowers are 5 to 15 cm (2.0 to 5.9 in) in diameter, deep pink, and appear on the side of the trunk. The flower tube has white tomentose thorns on the outside. The round to elliptical purple fruits are fleshy and thorny.^[2]
