GENUS INDEX

GENUS CODE: TAXOD
GENUS SCIENTIFIC: Taxodium
GENUS AUTHORITY: Rich.
GENUS COMMON: Bald cypress
GENUS SUMMARY: A genus of 3 species, trees, of e. North America and Mexico. There has been much debate over whether the two taxa of Taxodium in our area should be treated as species or varieties, and if as varieties, the proper nomenclature. I agree with Godfrey (1988), in his preference to recognize two species ... because it is my perception that the vast majority of trees (populations) are thus distinguishable. True intermediates appear to be non-existent, though the mimicry of the two species creates pseudo-intermediates that can cause difficulties in identification. Occasionally, the two species can be seen growing together, in hybrid habitats, as at the junction of Lake Waccamaw and the Waccamaw River (Columbus County, NC); a few recognizable intermediates can be seen. See Lickey & Walker (2002) for a contrary argument supporting varietal status. Neufeld (1986) discusses the different architecture and ecophysiology of the two species. The only other species in the genus is T. mucronatum Tenore, ranging from s. TX south to Mexico and Guatemala. West of the Mississippi River, the architecture of T. distichum comes to resemble that of T. mucronatum, suggesting the possibility of introgression. For this and other reasons, Watson in FNA (1993b) and other authors prefer to treat T. mucronatum as a third variety of T. distichum, T. distichum var. mexicanum Gordon. Taxodium is most closely related to Glyptostrobus and Cryptomeris.

FAMILY INDEX

FAMILY CODE: CUPRES
FAMILY SCIENTIFIC: Cupressaceae
FAMILY AUTHORITY: Bartlett 1830
FAMILY COMMON: Cypress Family
FAMILY SUMMARY: A family of about 29 genera and about 130 species. Recent studies indicate that the separation of the Taxodiaceae from the Cupressaceae is not warranted, and they are here combined (Gadek et al. 2000; Brunsfeld et al. 1994). The subfamilial classification used here follows Gadek et al. (2000).

SCIENTIFIC NAME: Taxodium ascendens
COMMON NAME: Pond-cypress
SYNONYMY: [= G, K, RAB, S, Va, WH3, Z; < T. distichum - F; = T. distichum var. imbricarium (Nuttall) Croom - FNA, Y; = T. distichum var. nutans (Aiton) Sweet]

HABITAT: Limesink ponds (dolines), clay-based Carolina bays, wet savannas, pocosins and other wet, peaty habitats, shores of natural blackwater lakes, swamps of blackwater streams.
COMMENTS: Se. VA south to s. FL, west to e. LA; it is surely one of the most scenic trees of eastern North America.
