Taxodium distichum is a deciduous conifer in the family Cupressaceae. It is native to the southeastern United States. Hardy and tough, this tree adapts to a wide range of soil types, whether wet, salty, dry, or swampy. It is noted for the russet-red fall color of its lacy needles.

Taxodium mucronatum, commonly known as Montezuma bald cypress, Montezuma cypress, or ahuehuete, is a species of Taxodium that is primarily native to Mexico and Guatemala, with a few populations in the southwestern United States. Ahuehuete is derived from the Nahuatl name for the tree, āhuēhuētl, which means "upright drum in water" or "old man of the water."
