Similar to Metasequoia, Taxodium has two types of branches; persistent woody branches and deciduous branchlets. The persistent woody branches with the alternate/spiral leaf arrangement is a useful identification feature and helps to separate this species from dawn redwood which is opposite.
Note: The long drooping structures in this image are male pollen cones, not stem structure.
