Pond cypress

''Taxodium ascendens'', also known as pond cypress, is a deciduous conifer of the genus ''Taxodium'', native to North America. Many botanists treat it as a variety of bald cypress, ''Taxodium distichum'' rather than as a distinct species, but it differs in ecology, occurring mainly in still blackwater rivers, ponds and swamps without silt-rich flood deposits. It predominates in cypress dome habitats.
