Cypress Knee


Can you spot the cypress knees?


Here's a closer shot!

Knees are woody projections sent above the normal water level, roughly horizontally from the roots, with a near-right-angle bend taking them roughly vertically downward into soil, usually passing through water first. One early assumption of their function was that they provided oxygen to the roots that grow in the low dissolved oxygen (DO) waters typical of a swamp (see also mangroves, which have similar adaptations), acting as pneumatophores. ~ SOURCE

  5. I saw them and I love them! We have swamps near where we spend winters now -- in Florida. The first ones I ever saw were when we spent a winter in Louisiana a few years ago. I will never forget those Bayous and was fascinated by the cypress knees.
