Hymenocallis, bulb extension again.

Regarding earlier discussions on bulbs maintaining their optimal depth, I just uploaded a picture of Hymenocallis sp. (probably littoralis) from an actively growing dune.   The dunes can easily grow 6" or more in one year, given favorable winds.  Out of almost 100 plants rescued from the ocean after hurricane Jeanne, most had these extensions or evidence that they had snapped off.  It looks like the extension acts to keep the bulb near the surface as sand builds up on the dune.  I thought it interesting that the oldest section resembles a rhizome.  Comments are appreciated.
