As the palpon clusters grew, more bracts were added in the anterior direction. In older parts of the colony new secondary gastrozooids formed in between primary gastrozooids (

Thus, by the time the colony was examined, few mature bracts remained attached directly to the siphosomal stem. Developing gastrozooid and palpon lateral bracts were very similar, though they became more distinct as they matured. Mature gastrozooid bracts were very elongate and straight without an obvious keel (

A). Mature palpon bracts tended to be more ovoid in shape and more curved, and they tapered to form a more rounded proximal end on the upper surface. In this case the mesoglea was generally thicker and, on the lower surface, it bulged out slightly to form a small, but distinct, keel. The bracteal canal arose from the proximal end of the bract. Nematocyst patches were scattered over the distal two-thirds of the upper side of the bracts (
