The pollen grain exine ofCentrolepis aristata(R.Br.) Boem. & Schultz. is like a quilt with top and bottom layers tied together at intervals with ring shaped fasteners, each having an open center (“scrobiculii”, Potonié 1934). Thus the top (tectum) extends down at intervals in the form of ring-shaped extensions providing continuity with the footlayer. In effect there are no columellae (bacules). The ectexine system is alveolate and much like the cap region of pollen ofPinus.
