| Apiaceae | Eryngium hookeri | Hooker's Eryngo | Ditches, other wet areas. | W. MS and AR west to OK and TX, perhaps recently adventive in the eastward portions of that distribution, not credited as occurring east of TX in Matthias & Constance (1945). |  |
| Apiaceae | Eryngium integrifolium | Savanna Eryngo | Pine savannas, pine flatwoods, seepages, swamps, wet meadows, other moist, nutrient-poor places. | Se. VA (Greensville County) (Belden et al. 2004) and e. NC south to ne. FL and Panhandle FL, west to OK and TX, inland in c. TN. |  |

| Apiaceae | Eryngium prostratum | Creeping Eryngo, Spreading Eryngo | Floodplain forests, bogs, pond margins, moist ditches and lawns, other moist, open habitats; definitely native southward, perhaps only rather recently spread to the northern parts of our area. | Se. VA south to FL, west to OK and TX. |  |
| Apiaceae | Eryngium ravenelii | Ravenel's Eryngo | Wet pine savannas, mostly or entirely over calcareous substrate. | Se. SC (Berkeley and Charleston counties) south to sw. GA and s. FL. Reports for se. NC are based on inland populations of E. aquaticum. |  |
| Apiaceae | Eryngium species 1 | Moccasin-master | Along small streams through longleaf pine savannas. | So far as is known, endemic to e. LA (Florida parishes), s. MS, and s. AL. | |
| Apiaceae | Eryngium yuccifolium var. synchaetum | Southern Rattlesnake-master | Wet savannas, especially those over calcareous clay soils. | A Southeastern Coastal Plain endemic: se. NC to s. FL and west across the Gulf Coastal Plain, the exact range limits obscure. |  |
| Apiaceae | Eryngium yuccifolium var. yuccifolium | Northern Rattlesnake-master | Diabase barrens and glades, olivine barrens, pine savannas, pine flatwoods over loamy or clay soils, wet to dry prairies, other open sites with at least periodic moisture, generally in sites showing some prairie affinities. | Widespread in southeastern and midwestern North America, the exact range limits of the typic variety and var. synchaetum somewhat obscure; probably distributed from NJ, OH, s. MI, WI, MN, and NE south to Panhandle FL, AL, MS, n. LA, and e. TX. |  |
