|---|---|---|---|---|---|
| Parnassiaceae | Parnassia asarifolia | Appalachian Parnassia, Kidney-leaved Grass-of-Parnassus, Appalachian Grass-of-Parnassus, Brook Parnassia | Bogs, sphagnous seeps, brookbanks, generally in more acidic habitats than P. grandifolia, up to elevations over 1800 m. | Virginia, e. West Virginia, sw. Arkansas south to Georgia; disjunct in the Coastal Plain of e. Texas and sc. Arkansas (in acidic seepages), but primarily in the Appalachian and Ozarkian highlands. |  (c) Stuart, Will |
| Parnassiaceae | Parnassia caroliniana | Savanna Parnassia, Carolina Grass-of-Parnassus, Eyebright | Wet longleaf pine, pond pine, or pond cypress savannas (especially but not strictly where shallowly underlain by coquina limestone), sandhill seepage bogs. | Se. and sc. North Carolina south through South Carolina; disjunct in the Panhandle of Florida, the distribution (at least now) fragmented and disjunct. In North Carolina, locally common in three small areas, centered around Maple Hill (Pender and Onslow counties), Old Dock (Columbus and Brunswick counties), and the Green Swamp (Brunswick County). |  (c) Griffith, Floyd A. |
| Parnassiaceae | Parnassia glauca | Fen Parnassia, American Grass-of-Parnassus, Fen Grass-of-Parnassus | Fens. | Newfoundland and Labrador (Newfoundland), Québec, and Saskatchewan south to New Jersey (Ocean County), s. Pennsylvania (Rhoads & Block 2007), Ohio, Indiana, Iowa, and South Dakota. |  (c) Danielson, Erik |
| Parnassiaceae | Parnassia grandifolia | Limeseep Parnassia, Bigleaf Grass-of-Parnassus | Fens, gravelly seepages, inland primarily or solely over calcareous, mafic, or ultramafic rocks; in the Coastal Plain in seepage over marl on nearly vertical river bluffs on the Cape Fear River (NC), and in acidic seepage bogs in pinelands. | Virginia, West Virginia, s. Missouri, and Oklahoma south to n. Georgia, Panhandle Florida, s. Mississippi (Sorrie & Leonard 1999), Arkansas, and e. Texas, primarily in the Appalachian and Ozarkian highlands. The discovery of populations of this species in Brunswick and Columbus counties, North Carolina, was remarkable. In the Panhandle of Florida and the West Gulf Coastal Plain of Louisiana and Texas it also occurs in wet savannas and pitcherplant bogs (MacRoberts, MacRoberts, & Jackson 2004), in Florida sometimes in close proximity to P. caroliniana; Parnassia in Coastal Plain savannas should not necessarily be assumed to be P. caroliniana. |  (c) Ware, Richard & Teresa - CC-BY-NC, permission granted to NCBG |
