|---|---|---|---|---|---|
| Magnoliaceae | Magnolia ×soulangeana | Saucer Magnolia, Tulip Magnolia | Cultivated, persistent or weakly naturalizing near plantings. | Reported for Barbour and Morgan counties, AL (D. Spaulding, pers. comm., 2013) and scattered other sites in eastern North America outside of our flora area (Kartesz 2010) | |
| Magnoliaceae | Magnolia acuminata var. acuminata | Cucumber-tree, Cucumber Magnolia | Mesic to subxeric forests, especially (but by no means strictly) over mafic or calcareous rocks, up to at least 1550m (where growing with Betula alleghaniensis, Abies fraseri, Picea rubens, and Sorbus americana), ultramafic outcrop barrens (where codominant with Pinus rigida and Quercus alba). | S. ME, MY, c. IN, s. MO, and e. OK, south to c. GA, w. Panhandle FL (Holmes and Walton counties), s. AL, s. MS, and w. LA. |  |
| Magnoliaceae | Magnolia acuminata var. subcordata | Yellow Cucumber-tree, Showy Cucumber Magnolia, Yellow-flowered Magnolia | Moist to dry slopes and bottomlands over mafic or calcareous rocks. | Var. subcordata ranges from sc. NC south to AL. |  |
| Magnoliaceae | Magnolia ashei | Ashe’s Magnolia | Moist to wet hammocks. | Endemic to FL Panhandle. |  |
| Magnoliaceae | Magnolia fraseri | Fraser Magnolia, Mountain Magnolia, Earleaf Umbrella-tree | Mesic to dry forests. | A Southern and Central Appalachian endemic: sw. PA (found in the 2010s, S. Grund, pers. comm., 2019), KY, and w. VA south through w. NC and e. TN to nw. SC, n. GA, and ne. AL. |  |
| Magnoliaceae | Magnolia grandiflora | Southern Magnolia, Bull Bay, Laurel | Maritime forests, mesic Coastal Plain bluffs and flats, bottomlands, now also widely naturalized, spreading from cultivation into wet to mesic (and even dry) forests. | The pre-Columbian range was apparently from se. NC south to c. peninsular FL, west to e. TX, largely on the Coastal Plain, now somewhat expanded northward and inland by naturalization from centuries of horticultural planting and spread by birds to nearby forests. |  |
| Magnoliaceae | Magnolia kobus | Kobus Magnolia, Kobushi Magnolia | Suburban woodlands. | Native of Japan. |  |
| Magnoliaceae | Magnolia macrophylla | Bigleaf Magnolia | Mesic forests, primarily over limestone, other calcareous sedimentary rocks (calcareous shales, sandstones, etc.), or mafic rocks (east of the Blue Ridge), mesic hammocks in the Coastal Plain. | S. OH and sw. VA south through e. TN to w. GA, west to AL, MS, n. LA, and se. AR (Sundell et al. 1999); disjunct on Crowleys Ridge in ne. AR (population now extirpated), c. and nc. SC, and e. SC (where probably not native). The range of this species is sometimes stated in such a way as to imply that it is a tree of the southern Blue Ridge, which it barely and marginally enters. Actually, it avoids the Southern Blue Ridge, reaching its greatest abundance in the sedimentary rock Appalachians west of the Blue Ridge, particularly the Cumberland Plateau, and occurs east of the Blue Ridge only as a rare disjunct. |  |
| Magnoliaceae | Magnolia pyramidata | Pyramid Magnolia | Mesic hammocks, mesic forests, especially of bluffs and ravines. | A Southeastern Coastal Plain endemic: c. SC south to Panhandle FL, west to e. TX. |  |
| Magnoliaceae | Magnolia stellata | Star Magnolia | Suburban woodlands. | Native of e. Asia. Reported for s. OH by Riley, Vincent, & Widrlechner (2020). |  |
| Magnoliaceae | Magnolia tripetala | Umbrella Magnolia, Umbrella-tree | Mesic forests, ravines. | Centered in the Southern Appalachians, but avoiding higher elevations, and therefore occurring primarily "around" the Blue Ridge; ranging from sc. and sw. PA, s. OH, s. IN south to SC, GA, Panhandle FL (Tobe 2007), AL, and MS; also disjunct in the Ouachita Mountains of c. AR and e. OK. |  |
| Magnoliaceae | Magnolia virginiana var. australis | Southern Sweet Bay | Pocosins, bay forests, and swamps in the Coastal Plain, streamhead pocosins, swamps, and sandhill seeps in the Sandhills, bogs and peaty swamps in the Piedmont and Mountains. | Se. NC south to s. FL, and west to e. TX, rarely extending into more interior provinces; disjunct in nw. Cuba. |  |
| Magnoliaceae | Magnolia virginiana var. virginiana | Northern Sweet Bay | Pocosins, bay forests, and swamps in the Coastal Plain, streamhead pocosins, swamps, and sandhill seeps in the fall-line Sandhills, bogs and peaty swamps in the Piedmont. | Se. MA south to w. NC, s. SC, and e. GA. |  |
