--><span class="statement" id="st-undefined" data-properties=""><b>Trees </b>deciduous or evergreen. <b>Branchlets</b> terete. <b>Lateral</b> roots commonly producing erect, irregularly conic to rounded "knees" in periodically flooded habitats. <b>Leaves</b> alternate, in 2 ranks or not. <b>Adult</b> leaves divergent to strongly appressed, linear or linear-lanceolate to deltate, generally flattened, free portion to ca. 17 mm; abaxial glands absent. <b>Pollen</b> cones with 10–20 sporophylls, each sporophyll with 2–10 pollen sacs. <b>Seed</b> cones maturing and shattering in 1 season, nearly globose; scales falling early, 5–10, valvate, ± peltate, thin and woody. <b>Seeds</b> (1–)2 per scale, irregularly 3-angled, wingless; cotyledons 4–9. <b>x</b> = 11.</span><!--

|discussion=<p>The pollen cones are usually borne at the base of alternate leaves, forming pendent axillary panicles; they occur less commonly singly or in racemes.</p><!--
--><p><i>Taxodium</i> is variously treated as one to three species but treated here as one polymorphic species with two varieties in the flora. A third taxon tentatively accorded varietal rank--- <i>Taxodium distichum</i> (Linnaeus) Richard <i></i>var.<i> mexicanum</i> Gordon (= <i>Taxodium</i> mucronatum Tenore)—and recognized by some authors as occurring within our range, appears to differ only in minor phenological characters. Whether or not populations from farther south in Mexico and Guatemala differ sufficiently for formal taxonomic recognition at any rank has yet to be determined.</p><!--
