After the spiral phase, which may last from several to many nodes, the arrangement reverts to decussate by the absorption of some of the leaf-bearing faces of the stem.
Brooker & Kleinig (2001) In all except a few species, the leaves form in pairs on opposite sides of a square stem, consecutive pairs being at right angles to each other (decussate).
The leaves emerge oppositely, each pair at right angles to the previous one (called decussate) or whorled.
The phyllotaxis is usually decussate, rarely whorled (e.g. Fadogia ), or rarely alternate resulting from the suppression of one leaf at each node (e.g. Sabicea sthenula).
