| Cupressaceae | Chamaecyparis | White Cedar |  (c) Ward, Scott G | ||
| Cupressaceae | Chamaecyparis lawsoniana | ||||
| Cupressaceae | Chamaecyparis pisifera | Sawara Cypress | Native of Japan. Reported for New Jersey (Bergen County) and New York (Orange County) by Kartesz (2022). | ||
| Cupressaceae | Chamaecyparis thyoides var. henryae | Panhandle White Cedar | Blackwater stream swamps, depression ponds and borrow pits with pond cypress, wet pine flatwood ecotones, ditches, borders of tidal wetlands. | Var. henryae is sometimes interpreted as endemic of the w. Panhandle of Florida and s. Alabama east of Mobile Bay, notably in the drainages of the Yellow River, Blackwater River, Escambia River, and Perdido River, with populations further west (in s. Mississippi) as being part of Chamaecyparis thyoides var. thyoides, or arguably in a third, unnamed, clade. | |
| Cupressaceae | Chamaecyparis thyoides var. thyoides | Atlantic White Cedar, Juniper | Peat dome and streamhead pocosins, blackwater stream swamps, hillside seepages, in highly acidic, peaty or sandy soils. | S. Maine south to n. Florida and west to s. Mississippi. The westernmost populations of Chamaecyparis thyoides have conflicting evidence as to identification as var. henryae or var. thyoides; they are here included in var. henryae, but may be better considered as part of var. thyoides or as a separate taxon. From New Jersey south it is strictly a tree of the Coastal Plain; northward it is often found in kettle-hole bogs. In South Carolina and Georgia, C. thyoides is absent in the outer Coastal Plain, occurring primarily in the fall-line Sandhills. | (c) Ward, Scott G |

| Cupressaceae | Juniperus | Red Cedar, Juniper, Savin |  (c) Bradley, Keith | ||
| Cupressaceae | Juniperus ashei | Ashe Juniper, Rock Cedar, Ozark White-cedar | Exposed calcareous bluffs and glades, usually on very steep slopes atop cliffs or on flat glades with much exposed bedrock. | S. Missouri, Arkansas, and Oklahoma south to Texas (especially the Edwards Plateau) and adjacent Mexico (Coahuila, Nuevo León). |  (c) Hill, Sonnia |

| Cupressaceae | Juniperus communis var. communis | European Common Juniper | Forests, fens, pastures, disturbed areas. | Native of Eurasia. |  (c) Fleming, Gary P. |
| Cupressaceae | Juniperus communis var. depressa | Ground Juniper, Mountain Juniper, Common Juniper | In thin soil around rock outcrops on mountain summits and Piedmont monadnocks and rocky bluffs (in GA and NC), high elevation old fields (in VA), xeric Coastal Plain sandhills (in SC and VA). | Juniperus communis is circumpolar, widespread in n. North America, n. Europe, and n. Asia. Adams (2008a, 2008b, 2008c, 2018) recognizes five varieties in North America, all native eastern North American plants belonging to var. depressa. In North America J. communis s.l. is primarily northern and montane, occurring nearly throughout Canada and Alaska, south in the Appalachians to South Carolina, Georgia, and Alabama, south in the Rocky Mountains to New Mexico, Arizona, and California. It is sometimes planted as a landscaping plant. In e. North America, it is rare and scattered south of Pennsylvania, Michigan, and Wisconsin, ranging south to a few disjunct sites in Virginia, North Carolina, South Carolina, Georgia, and s. Indiana, in our area notably known from Mount Satulah (Macon County, North Carolina), King's Pinnacle (Gaston County, North Carolina), and in sandy soils at Hitchcock Woods (Aiken County, South Carolina). |  (c) Cressler, Alan M. |
| Cupressaceae | Juniperus conferta | Japanese Shore Juniper | Roadsides. | Native of Japan. Reported as naturalizing in Alabama (Barger, et al. 2012). Also reported for Massachusetts. |  (c) Atha, Daniel - CC0 |
| Cupressaceae | Juniperus horizontalis | Creeping Juniper | Sand dunes. | Newfoundland and Labrador west to Alaska, south to New York, n. Ohio, nw. Indiana, Illinois, Iowa, Nebraska, Wyoming, Montana, and British Columbia. A record from Long Island appears to be a false report. |  (c) Steven, Daniel - C, permission granted to NCBG |
| Cupressaceae | Juniperus ovata | Adams Juniper, West Texan Ashe Juniper | Limestone outcrops and calcareous gravels. | Primarily in w. Texas and Coahuila, but also apparently isolated near New Braunfels (Adams 2008d). |  (c) McGreevy, Elizabeth |
| Cupressaceae | Juniperus pinchotii | Redberry Juniper | Gravelly and sandy outcrops. | C. and w. Oklahoma south to c. Texas, s. Texas (Duval County), s. New Mexico to Mexico (Chihuahua, Coahuila, Durango, Nuevo León). |  (c) Hill, Sonnia |
| Cupressaceae | Juniperus silicicola | Southern Red Cedar, Coastal Red Cedar | Maritime forests and maritime scrub, hammocks, coastal shell middens and natural shell deposits, brackish marshes, pine rocklands in s. FL, and other sandy or peaty, circumneutral situations. | Se. Virginia (?) south to s. Florida, west to e. Louisiana (Florida Parishes); reports from further west (e.g. Texas) are misidentifications. Virginia records are ambiguous (see Virginia Botanical Associates 2023). |  (c) Cressler, Alan M. |
| Cupressaceae | Juniperus virginiana | Eastern Red Cedar, Cyprès rouge (frc), Cèdre rouge (frc) | Bluffs, glades, upland forests and woodlands, pastures, old fields, roadsides, and fencerows, primarily upland, occurring most abundantly on (but by no means restricted to) circumneutral soils (including shrink-swell clays) derived from mafic or calcareous rocks. | S. Maine west to e. North Dakota, south to n. Florida, s. Alabama, s. Mississippi, s. Louisiana, and c. Texas; disjunct in Coahuila, Mexico (Adams 2011). Though native, this evergreen is aggressive in a variety of historically open habitats. Its spread is due largely to widespread fire suppression over the past century or so and widespread, open grazing of cattle, which avoid cedar while eating its competition. While it thrives in calcareous soils, it is not restricted to them. |  (c) Fleming, Gary P. |

| Cupressaceae | Platycladus orientalis | Oriental Arborvitae, Tree-of-life | Commonly planted, especially in graveyards, and rarely persisting and spreading to pastures, fields, and roadsides. | Native of Asia. | (c) Campos, Aidan |

| Cupressaceae | Sequoiadendron giganteum | ||||
| Cupressaceae | Taxodium | Bald-cypress |  (c) Bradley, Keith | ||
| Cupressaceae | Taxodium ascendens | Pond-cypress | Limesink ponds (dolines), clay-based Carolina bays, wet savannas, pocosins and other wet, peaty habitats, shores of natural blackwater lakes, swamps of blackwater streams, forming "domes" and "stringers" in Florida in very flat, fire landscapes, also as "hatrack" stands of widely spaced and stunted trees on oolite in south Florida. | Se. Virginia south to s. Florida, west to e. Louisiana. |  (c) mfeaver - CC-BY |
| Cupressaceae | Taxodium distichum | Bald-cypress, Cypre (frc), Cipre (frc) | Brownwater and blackwater swamps, usually in riverine situations, depressions in bottomland forests, lake margins, river banks, rarely in wooded seeps. | Delaware and e. Maryland south to s. Florida and west to e. Texas and se. Oklahoma, north along the Mississippi River and its tributaries to s. Indiana and s. Illinois. This species is sometimes planted as an ornamental in upland and wetland sites within and beyond its natural range, and these planted trees are very long persistent and may be encountered. | (c) Bradley, Keith |
| Cupressaceae | Taxodium mucronatum | Montezuma Bald-cypress, Mexican Bald-cypress, Ahuehuete, Sabino | Riverbanks of the Rio Grande River, streams, and resacas. | S. Texas (perhaps as far north as San Antonio) south to s. Mexico. |  (c) Hardin, J.W. |
| Cupressaceae | Thuja | Arborvitae | (c) Bradley, Keith | ||
| Cupressaceae | Thuja occidentalis | American Arborvitae, Northern White Cedar, Flat Cedar | Dry limestone, dolostone, and calcareous sandstone cliffs, talus, and boulderfields, also planted and persisting around old homesites and cemeteries (mainly in the Mountains). Rarely (in our area) in calcareous swamps; this is more characteristic in the broader Great Lakes region where this species can be found abundantly within rich swampy hummocks of alkaline fens as well as in drier, thinner soils of Great Lakes alvars. | Nova Scotia, Hudson Bay, and Manitoba south to Pennsylvania (where considered strictly introduced by Rhoads & Block 2007), Ohio, n. Indiana, n. Illinois, and in the mountains to West Virginia, w. Virginia, and e. Tennessee. This species has been alleged by various authors to have occurred as a native species in nw. North Carolina on limestone bluffs in Alleghany, Ashe, and/or Burke counties, but it has not been relocated in this century, and little apparently suitable habitat occurs in North Carolina. | (c) Bradley, Keith |
