Are cypress knees unique to cypress trees, or do other trees have similar adaptations?

Question

ForwardPlant Team · Accepted Answer

While cypress knees are famously associated with cypress trees, they are not entirely unique in their adaptive function.  Some other wetland trees, like mangroves and certain cypress relatives such as baldcypress, develop similar pneumatophores or "breathing roots." These structures help facilitate gas exchange in waterlogged, anoxic soils, allowing the trees to thrive in challenging environments where oxygen is scarce.
