The rhizome shoots are air-bearing. From the rhizome nodes — and partly from the primary vertical shoots as well — secondary shoots grow upward into the light and ensure the propagation of the vegetative stand. The vertical rhizomes penetrate the compaction zone with great dynamism, to branch out again horizontally on a deeper water-bearing stratum. Even from depths of three to four metres they send their black-brown rhizome shoots upward from there (Figure 34, p. 449).
