Palm tree saxophones

When the sea first exposes the roots of sabal palms, a fuzz of sand-gripping tentacles wiggles in the air:

This haircut reveals a curious structure at the very bottom of the former root ball, a curved trumpet of hard wood. The horn is narrow at the side, then widens as it twists upward into the center of the root mass:

Unlike every other tree that I know of (other examples are welcome!), the palm germinates then grows down into the soil for up to half a meter. It then turns up its growing tip and sends young fronds to the surface. This burrowing infancy takes the sensitive growing tip down where it is less vulnerable to fire, drought, and herbivores. Botanists call the growth form a “saxophone”: a narrow down-pointing neck that splays as it curves back up.

The first toot of the sax:
