|---|---|---|---|---|---|
| Boraginaceae | Lithospermum canescens | Hoary Puccoon, Indian-paint | Dry woodlands and glades over calcareous rocks (such as limestone, dolostone) or mafic rocks (such as diabase). | ON west to SK, south to c. NC, nw. GA, AL, LA (Caldwell Parish) and TX. |  (c) Sorrie, Bruce A. - CC-BY |
| Boraginaceae | Lithospermum caroliniense | Coastal Plain Puccoon | Longleaf pine sandhills, other dry sandy soils. | A Southeastern Coastal Plain endemic: se. SC south to Panhandle FL, and west to AR and TX; disjunct in se. VA. The disjunction from SC to se. VA, skipping over large amounts of apparently suitable sandhill habitat in NC, is surprising. | |
| Boraginaceae | Lithospermum croceum | Hairy Puccoon | Sandy prairies. | ON west to MT, south to nw. PA, n. OH, AR, OK, and CO. |  (c) Faulkner, Erin - CC-BY-NC, permission granted to NCBG |
| Boraginaceae | Lithospermum decipiens | Deceptive Marbleseed | Dolomitic Ketona glades. | Endemic to c. AL (Bibb County) (Allison & Stevens 2001). |  (c) Sorrie, Bruce A. - CC-BY |
| Boraginaceae | Lithospermum helleri | Heller's Marbleseed | Juniper-oak woodlands over limestone. | Edwards Plateau of TX and Lampasas Cut Plain. |  (c) Wong, Michelle - CC-BY |
| Boraginaceae | Lithospermum incisum | Narrowleaf Gromwell, Yellow Puccoon, Fringed Puccoon | Prairies, woodlands, disturbed areas. | S. ON west to BC, south to IN, LA, TX, CA, and Mexico; disjunct in FL, from FL Panhandle south to c. peninsular FL. |  (c) Sorrie, Bruce A. - CC-BY |
| Boraginaceae | Lithospermum latifolium | American Gromwell, Broadleaf Gromwell, Broadleaf Puccoon | Dry to moist woodlands over calcareous rocks. | NY west to MN, south to nw. GA, s. TN and AR. |  (c) Ware, Richard & Teresa - CC-BY-NC, permission granted to NCBG |
| Boraginaceae | Lithospermum matamorense | Rough Gromwell | Thickets, woodlands, floodplains. | Se. TX, c. TX, w. TX, south through s. TX to n. Mexico (COA, NLE, SLP, TAM). |  (c) Faulkner, Erin - CC-BY-NC, permission granted to NCBG |
| Boraginaceae | Lithospermum mirabile | San Antonio Stoneseed | Brushlands. | Se. TX, s. TX, c. TX, w. TX, and s. NM south to n. Mexico (COA, NLE). |  (c) Wong, Michelle - CC-BY |
| Boraginaceae | Lithospermum molle | Tennessee Marbleseed | Limestone barrens. | C. KY, c. TN (Chester, Wofford, & Kral 1997), nw. AL, and disjunct in the Ozarkian Highlands of MO. O. molle has been attributed to Durham County, NC (RAB); Baskin et al. (1983) determined that this report was based on a misidentification of a specimen of O. virginianum. |  (c) Smith, Jake - CC-BY-NC, permission granted to NCBG |
| Boraginaceae | Lithospermum occidentale | Western Marbleseed | Open woodlands over limestone. | WI west to MT, south to nw. AR, TX, NM, and UT. |  (c) Roberts, Jo - CC-BY |
| Boraginaceae | Lithospermum officinale | European Gromwell | Disturbed areas, roadsides, pastures. | Native of Europe and occurring at scattered localities in ne. North America, south to PA and NJ (Kartesz 1999). |  (c) Sorrie, Bruce A. - CC-BY |
| Boraginaceae | Lithospermum onosmodium | Southwestern Marbleseed | Rocky barrens and woodlands, glades. | Wc. and sw. AR and e. OK south to c. and se. TX and sw. LA; disjunct eastwards in TN. |  (c) Ware, Richard & Teresa - CC-BY-NC, permission granted to NCBG |
| Boraginaceae | Lithospermum parviflorum | Eastern Prairie Marbleseed, Shaggy Marbleseed | Calcareous woodlands, barrens, and glades, and nearby in disturbed areas, such as older pasture edges. | W. NY and ON west to MN, south to sc. PA (Rhoads & Klein 1993), w. VA, e. TN (Chester, Wofford, & Kral 1997), LA, and TX. This species was attributed to NC by F and S; the documentation of these reports is not known. |  (c) Fleming, Gary P. |
| Boraginaceae | Lithospermum subsetosum | Ozark Marbleseed | Calcareous glades and woodlands. | MO south to AR and OK; disjunct in c. TN (Chester, Wofford, & Kral 1997) and ne. AL (Cumberland Plateau escarpment) (Datillo & Nestor 2011; D. Estes, pers. comm., 2011). |  (c) Aaron, Nathan - CC-BY |
| Boraginaceae | Lithospermum tuberosum | Southern Stoneseed | Nutrient-rich forests, especially over calcareous rocks. | Sw. VA, s. WV, KY, and TN, south to n. peninsular FL, FL Panhandle, and LA. |  (c) Ward, Scott G |
| Boraginaceae | Lithospermum virginianum | Pineland Marbleseed, Virginia Marbleseed | Longleaf pine sandhills, shell middens in the outer Coastal Plain, woodlands and barrens over diabase and other mafic rocks in the Piedmont and low Mountains, barrens, glades, or woodlands over calcareous rocks in the Mountains (the unifying ecological factor determining its distribution may be an open, woodland condition maintained by fire). | LA to FL, north to NY and MA, primarily on the Coastal Plain; the species has become very rare north of NC. |  (c) Sorrie, Bruce A. - CC-BY |
