All vessel elements in the parasitic dicot Ombrophytum subterraneum (Balanophoraceae) have irregular, knobby ingrowths on their secondary walls. The ingrowths have a mean spacing of about 4 μ m and can be longer than 6.4 μ m, thus causing considerable occlusion of all but the widest vessel elements. The adaptive value is unknown.
